A spring has an unstretched length of 10 cm . It exerts a restoring force F when stretched to a length of 11 cm .
Answers
L = 10 cm, original length
Because the stretched length is 11 cm, the extension is
d = 11 - 10 = 1 cm
Let the spring constant be k N/cm
Then the restoring force is
F = (k N/cm)*(1 cm)
= k N
Answer:
The restoring force is equal to the spring constant, measured in Newtons per centimeter.
(a). The restoring force in the spring will be [tex]3F[/tex] if it is stretched to a length of [tex]\boxed{13\,{\text{cm}}}[/tex] .
(b). The restoring force in the spring will be [tex]2F[/tex] if it is compressed to a length of [tex]\boxed{8\,{\text{cm}}}[/tex] .
Further Explanation:
When we compress or stretch a spring from its natural length, there is a restoring force developed in the spring due to the compression and stretching of the spring.
The restoring force experienced by the spring due to stretching is expressed as:
[tex]F=k\cdot\Delta x[/tex] …… (1)
Here, [tex]F[/tex] is the restoring force developed in the spring, [tex]k[/tex] is the spring constant of the spring and [tex]\Delta x[/tex] is the length through which the spring is stretched.
The spring experiences a restoring force of [tex]F[/tex] when it is stretched to a length of [tex]11\,{\text{cm}}[/tex] from its natural length [tex]10\,{\text{cm}}[/tex] .
[tex]\begin{aligned}\Delta x&={x_f} - {x_i}\\&=0.10 - 0.11\\&=0.01\,{\text{m}}\\\end{aligned}[/tex]
Substitute the values of force and change in length in equation (1).
[tex]\begin{aligned}F&=k\cdot0.01\hfill\\k&=\frac{F}{{0.01}}\hfill\\\end{aligned}[/tex]
Part (a):
When the spring experiences a restoring force of [tex]3F[/tex] , then the stretched length of the spring should be:
[tex]3F=k.\Delta x[/tex]
Substitute [tex]\frac{F}{{0.01}}[/tex] for [tex]k[/tex] in above expression.
[tex]\begin{aligned}3F&=\frac{F}{{0.01}}\cdot\Delta x' \\\Delta x'&=3\times0.01\,{\text{m}}\\&=3\,{\text{cm}}\\\end{aligned}[/tex]
So, the stretched length of the spring becomes:
[tex]\begin{aligned}L&={x_o}+\Delta x' \\&=10\,{\text{cm}}+3\,{\text{cm}}\\&=13\,{\text{cm}}\\\end{aligned}[/tex]
Thus, the restoring force in the spring will be [tex]3F[/tex] if it is stretched to a length of [tex]\boxed{13\,{\text{cm}}}[/tex] .
Part (b):
The restoring force of magnitude [tex]2F[/tex] is experienced by the spring on compression. The change in length due to compression will be:
[tex]2F=k\cdot\Delta x''[/tex]
Substitute [tex]\frac{F}{{0.01}}[/tex] for [tex]k[/tex] in above expression.
[tex]\begin{aligned}2F&=\frac{F}{{0.01}}\cdot\Delta x''\\\Delta x''&=2\times0.01\,{\text{m}}\\&=2\,{\text{cm}}\\\end{aligned}[/tex]
So, the compressed length of the spring becomes:
[tex]\begin{aligned}L'&={x_o}-\Delta x''\\&=10\,{\text{cm}}-{\text{2}}\,{\text{cm}}\\&=8\,{\text{cm}}\\\end{aligned}[/tex]
Thus, the restoring force in the spring will be [tex]2F[/tex] if it is compressed to a length of [tex]\boxed{8\,{\text{cm}}}[/tex] .

Work of 2 joules is done in stretching a spring from its natural length to 11 cm beyond its natural length. what is the force (in newtons) that holds the spring stretched at the same distance (11 cm)
Answers
If you want to find work done by a spring, this can be solved by using differential equations. However, derived equations are already ready for use. The equation is
W = k[{x₂-x₁)² - (x₁-xn)²],
where
xn is the natural length
x₁ is the stretched length
x₂ is also the stretched length when stretched even further than x₁
In this case xn =x₁. So, that means that (x₁-xn) = 0 and (x₂-x₁) = 11 cm or 0.11 m.
Then, substituting the values,
2 J = k (0.11² -0²)
k = 165.29 N/m
Finally, we use the value of k to the Hooke's Law to determine the Force.
F = kΔx = (165.29 N/m)(0.11 m)
F = 18.18 Newtons
Final answer:
To find the force holding a spring stretched at 11 cm, the spring constant is first calculated using the work done to stretch the spring. The spring constant is found to be approximately 330.58 N/m. The force is then calculated as 36.36 N.
Explanation:
The question relates to calculating the force that holds a spring stretched at a particular distance, given the work done to stretch the spring. The work to stretch (or compress) a Hooke's law spring by a displacement x is 0.5kx², where k is the spring constant, and x is the displacement. We know that 2 joules of work is done to stretch the spring 11 cm; we can use this information to calculate the spring constant and then find the force.
First, we convert 11 cm to meters by dividing by 100 to get 0.11 meters. Then, rearrange the spring work formula to solve for k:
W = 1/2 k x^2
2 = 1/2 k (0.11)^2
k = (2 * 2) / (0.11)^2
k = 4 / 0.0121
k = approximately 330.58 N/m
Once we have the spring constant, we can calculate the force that the spring exerts when stretched 11 cm:
F = k x
F = 330.58 N/m * 0.11 m
F = 36.36 N
Therefore, the force that holds the spring stretched at 11 cm is 36.36 N.
If a catcher catches a 0.5 kg baseball moving at 17.1 m/s in his glove, what is the average force in newtons on the glove during the catch if it takes 0.1 seconds to stop the ball?
Answers
The average force on the glove during the catch of a baseball with an initial velocity of 17.1 m/s and a mass of 0.5 kg, brought to rest in 0.1 seconds, can be calculated using the impulse-momentum theorem, resulting in an average force of 85.5 newtons.
The question involves the concept of impulse and the physics of motion. In physics, impulse is equal to the change in momentum of an object when a force is applied over a duration of time. The formula to calculate the impulse J is J = Ft, where F is the average force and t is the time period the force is applied. The change in momentum can also be written as m[tex](v_f - v_i)[/tex], where m is the mass, [tex]v_f[/tex] is the final velocity, and [tex]v_i[/tex]is the initial velocity. In this scenario, the baseball's initial velocity is 17.1 m/s, the mass of the baseball is 0.5 kg, and it is brought to rest (final velocity 0 m/s) in 0.1 seconds, resulting in a change in velocity of -17.1 m/s.
Using the impulse-momentum theorem, we can calculate the average force on the glove during the catch by rearranging the impulse formula to solve for the average force F. The calculation would thus be:
F = m * ([tex]v_f - v_i[/tex]) / t
F = 0.5 kg * (-17.1 m/s - 0 m/s) / 0.1 s
F = -85.5 N (The negative sign indicates that the force is in the opposite direction of the ball's initial motion, i.e., it is a decelerating force.)
Therefore, the average force on the glove is 85.5 newtons.
Why can a bridge surface freeze before adjoining road surfaces do?
Answers
The bridge surface can freeze before adjoining road surfaces do because of the difference in heat transfer. The bridge loses heat faster due to exposure to the cold air from above and below, while the roads are insulated by the ground.
Explanation:The reason why a bridge surface can freeze before adjoining road surfaces do is due to the difference in heat transfer.
When it is cold outside, the bridge surface is exposed to the cold air from above and below, causing it to lose heat rapidly. On the other hand, the adjoining road surfaces are in contact with the ground, which acts as an insulator and slows down the heat loss.
As a result, the bridge surface reaches the freezing temperature faster than the adjoining road surfaces, leading to the formation of ice on the bridge while the roads remain clear.
What is the magnitude of the resultant force, in newtons, acting on an object that has two forces acting in the same direction having magnitudes of 15 newtons and 25 newtons and a third force acting perpendicular to the first two having a magnitude of 30 newtons?
Answers
Imagining that the forces form a right triangle (since the 3rd force is acting perpendicularly) then the resultant force can simply be calculated using the hypotenuse formula:
c^2 = a^2 + b^2
Where a and b is equivalent to:
a = 15 N + 25 N = 40 N
b = 30 N
Therefore the resultant force is then calculated:
c^2 = (40 N)^2 + (30 N)^2
c^2 = 1,600 + 900
c^2 = 2,500
c = 50 N
Answer:
To find the magnitude of the resultant force, we can use the Pythagorean theorem and the trigonometric ratios.
First, we need to find the horizontal and vertical components of the two forces acting in the same direction:
Horizontal component = 15 N + 25 N = 40 N
Vertical component = 0 N (since the forces are in the same direction)
Next, we need to find the horizontal and vertical components of the third force acting perpendicular to the first two:
Horizontal component = 0 N (since the force is perpendicular to the other forces)
Vertical component = 30 N
Now, we can find the horizontal and vertical components of the resultant force:
Horizontal component = 40 N + 0 N = 40 N
Vertical component = 0 N + 30 N = 30 N
Using the Pythagorean theorem, we can find the magnitude of the resultant force:
Resultant force = sqrt((40 N)^2 + (30 N)^2)
Resultant force = sqrt(1600 N^2 + 900 N^2)
Resultant force = sqrt(2500 N^2)
Resultant force = 50 N
Therefore, the magnitude of the resultant force is 50 newtons.

Answers
Answer:
B.An electromagnetic field interacts with charged particles.
Explanation:
As we know that electromagnetic field is the combination of electric field and magnetic field both.
If the electric field or magnetic will interact with charge particle then due to interaction of charge particles with the field there is force on the charge particle which is given as
for electric field
[tex]F = qE[/tex]
for magnetic field
[tex]F = q(v \times B)[/tex]
so in both cases the charge particle will have interaction with magnetic field or electric field
so correct answer would be
B.An electromagnetic field interacts with charged particles.
Electromagnetic force occurs when an electromagnetic field interacts with charged particles. The correct option is (B).
When charged particles interact with an electromagnetic field, electromagnetic force results. Along with gravity, the weak nuclear force, and the strong nuclear force, this force is one of the four fundamental forces of nature.
Electric charges or electric currents cause an electromagnetic field to form. When charged particles, such as electrons or protons, are near an electromagnetic field, the interaction between their charge and the field causes them to feel a force.
The electromagnetic force is given by:
F = q(E + v×B)
Many commonplace phenomena and technology applications are fundamentally influenced by electromagnetic force. It is in charge of numerous electromagnetic phenomena, including interactions between charged particles, electrical circuit behavior, the creation of magnetic fields, and many more.
Hence, electromagnetic force occurs when an electromagnetic field interacts with charged particles. The correct option is (B).

C) The physical properties of the substance change, and all three properties must be re-measured. D) The mass and volume are both divided by two, but the density remains the same.
Answers
Final answer:
When an object is cut in half, its mass and volume are divided by two, but its density remains constant because both mass and volume change proportionately.
Explanation:
When Connelly cuts a solid object in half, both the mass and volume are divided by two. However, density, which is defined as the mass of an object divided by its volume, remains unchanged. This is because both the mass and volume change proportionately, which means the ratio of mass to volume (density) does not alter.
Therefore, the correct answer to what happens to the mass, volume, and density of the object that Connelly cuts is: D) The mass and volume are both divided by two, but the density remains the same.

2. A 14.8-kg child sits in a 1.30-kg swing. You pull the swing back, lifting it 52.1 cm vertically, and then let go. Determine the speed of the child and swing as the swing moves past its lowest point.
Answers
To answer this problem, we have to define the two energies, Potential and Kinetic Energy.
Initially when the child is at rest at 52.1 cm, the potential energy PE is at its highest.
PE = m g h
Where,
m = total mass = 14.8 kg + 1.30 kg = 16.10 kg
g = gravitational acceleration = 9.8 m /s^2
h = height = 52.1 cm = 0.521 m
Computing for PE:
PE = 16.10 * 9.8 * 0.521
PE = 82.29 N
As the swing moves past its lowest point h = 0, then all PE is converted to Kinetic Energy KE. Therefore, at lowest point
KE = 82.29
KE = 0.5 m v^2
0.5 (16.10) v^2 = 82.29
v = 3.20 m/s
A car slows down at -5.00 m/s^2 until it comes to a stop after travelling 15.0 m. How much time did it take to stop?
Answers
x = v₁t + 1/2 at²
a = (v₂-v₁)/t
where
x is the distance travelled
v₁ is the initial velocity
v₂ is the final velocity
a is the acceleration
t is the time
Now, we solve first the second equation. Since it mentions that the car comes eventually to a stop, v₂ = 0. Then,
-5 = (0-v₁)/t
-5t = -v₁
v₁ = 5t
We use this new equation to substitute to the first one:
x = v₁t + 1/2 at²
15 = 5t(t) + 1/2(-5)t²
15 = 5t² - 5/2 t²
15 = 5/2 t²
5t² = 30
t² = 30/5 = 6
t = √6 = 2.45
Therefore, the time it took to travel 15 m at a deceleration of -5 m/s² is 2.45 seconds.
The time it took for the car to stop, given an acceleration of -5.00 m/s^2 and a distance of 15.0 m, is approximately 2.45 seconds.
Explanation:The subject of this question is physics, more specifically the concept of acceleration. Given the car's acceleration is -5.00 m/s^2 (negative because it is slowing down) and it traveled a distance of 15.0 m, we can use the equation of motion to find the time it took for the car to stop. The equation that suits this situation best is d = ut + 0.5at^2. In this case, the initial velocity (u) is what we need to find first.
Assuming that the acceleration was constant, we can apply the third equation of motion:
v^2 = u^2 + 2as
We have v (final velocity) = 0 m/s (since the car stops), a = -5.00 m/s^2, and s = 15.0 m. Solving this equation for u (initial velocity) gives u = sqrt(v^2 - 2as) = sqrt(0 - 2 * -5 * 15) = sqrt(150) = ~12.25 m/s. Using this initial velocity value, we can now find the time it took for the car to stop using the first equation of motion (v = u + at). We know v = 0, u = ~12.25 m/s, and a = -5.00 m/s^2. Solving this for time (t), we have t = (v - u) / a = (0 - 12.25) / -5 = ~2.45 seconds.

Which are descriptions of gravity on Earth? Check all that apply.
an attractive force
a repulsive force
a noncontact force
a contact force
a horizontal force
a vertical force
Answers
The gravity is described by an attractive force, non-contact force and vertical force. Thus, options (a), (c) and (f) are correct.
The gravity is an attractive force that acts between the objects or particles kept on the of Earth and the Earth itself. The force is proportional to the product of masses of particles/objects and Earth. Since, the earth carry more mass, therefore, all objects are attracted towards the centre of Earth.
Gravity is an attractive force, where all the matters of Earth are attracted towards the Earth.Gravity cannot be repulsive on Earth, because earth is very heavy comparing to objects in the Earth. Thus, the repulsive force does not describe the gravity.Gravity do need the exact contact between the Earth surface and object. For example: A ball thrown in air is pulled towards the Earth due to gravity. Thus, gravitational force or gravity is a non-contact force.As discussed above, the gravitational force is non-contact force, therefore it cannot be contact force.Gravitational force or gravity always has its influence towards the downward direction rather than horizontal direction. Therefore, the horizontal force does not describe the gravity.As per above discussion, the gravity has downward influence. Therefore, it is a vertical force.Thus, we can conclude that gravity is described by an attractive force, non-contact force and vertical force.

What is the magnitude of the relativistic momentum of a proton with a relativistic total energy of 2.7 3 10210 j?
Answers
The equation that is applicable to this problem is expressed as
p = γmu
where p is the relativistic momentum, m is equal to the proton mass and u is the speed of proton. γ is equal to 1/√(1 - u²/c²) where c is the speed of light.
Another equation to determine p fully is to use this relativistic equation:
E = γmc²
where E is the total kinetic energy including the gamma energy.
We are given with E = 2.7 × 10^(-10) J and from a proton’s data, mc^2 = 938.27201 MeV. Using the conversion from MeV to J which is 1 eV = 1.60218 * 10^(-19) J, we compute for γ
γ=E/mc^2 =2.7 × 10^(-10) J / 938.27201x10^6 eV *(1.60218 * 10^(-19) J/eV) = 1.80
we use this number to determine u from the second equation γ = 1/√(1 - u²/c²)
we square both sides and cross multiply, resulting to
γ² (1 - u²/c²) = 1
u²/c² = (γ² -1)/γ²
u = c/y sq rt of (γ² -1)
u = 0.83
Substituting eventually to the first equation, we get
p = γmu
p = 1.80 * 1.67262 * 10^(-27) kg * 0.83 * 2.99792 * 10^8 m/s
p = 7.481 * 10^(-19) kg.m/s
