Momentum Monster does 600,000 joules of work in 10 seconds. How much power is that in watts?

I think it's 60,000, but I need someone who knows for sure whether this is correct or not.

Answer:

c. gravitational potential energy

Explanation:

Gravitational potential energy is the form of energy possessed by an object which is located at a certain height above the ground. This energy is given by:

[tex]U=mgh[/tex]

where:

m is the mass of the object

g is the gravitational acceleration (g=9.8 m/s^2)

h is the height of the object with respect to the ground

We have to note that gravitational potential energy is always measured with respect to a reference altitude (generally, the ground), because the value of h depends on the point chosen as reference.

Final answer:

To find the friction force given mass and acceleration, you can use Newton's second law of motion, F = m * a.

Explanation:

To find the friction force given mass and acceleration, you can use Newton's second law of motion. The formula is F = m * a, where F is the force, m is the mass, and a is the acceleration. The force of friction can be calculated using this formula, as long as the acceleration is due to friction.

For example, if you have a mass of 10 kg and an acceleration of 2 m/s² due to friction, the friction force can be found as follows: F = 10 kg * 2 m/s² = 20 N.

Remember to consider the direction of the force and acceleration when interpreting the results.

The binding energy of the Boron nucleus, 11 5B, is computed from its mass defect and converted from joules per nucleus to MeV per nucleon using provided conversion factors. The final binding energy is approximately 0.000494 MeV (or 494 KeV) to four significant figures.

In Physics, the binding energy of a nucleus refers to the amount of energy needed to separate it into individual protons and neutrons. We can calculate this using the mass-energy equivalence equation as it relates to the mass defect. For example, the binding energy of the Boron nucleus, 11 5B, can be determined from its mass defect.

Based on the provided values, the binding energy in joule per nucleus is 7.913 × 10-¹1 J. Switching this to the units of MeV (Mega electron volts) per nucleon, we can use the conversion factor of 1 MeV equals 1.602 × 10-¹³ J. This yields approximately 494 MeV.

To express this in terms of millions of electron volts to four significant figures as requested, divide by 1,000,000. This gives the final binding energy as 0.000494 MeV, or 494 KeV (Kilo electron Volts) to four significant figures.

The Black Hills of South Dakota is an example of an eroded "batholith".

Magma does not generally achieve the surface. In the event that gas weights are not sufficiently extraordinary to constrain the magma to the surface, or if overlying rocks can't be infiltrated by it, the magma may gradually cool and frame an extensive pool of stone. Stone is effortlessly unmistakable by its extensive gem structure and blend of minerals, including light-hued quartzes and darker feldspars and micas. An expansive district of intru-sive molten shake, found profound inside the outside, is known as a batholith. Batholiths can frame the center of a mountain run. This batholith, once framed profound inside Earth's outside layer, is presently uncovered at an elevation surpassing 3300 meters (10,000 ft) above ocean level. The Black Hills of South Dakota are another exemplary case of this sort of geologic development.

To calculate the emitted power per square meter for an object at 2600 K, we use the Stefan-Boltzmann law with a value of 5.67 × 10^-8 W/m^2/K^4 for the Stefan-Boltzmann constant. The result for the given object is approximately 1.53 × 10^7 W/m^2.

Explanation:

Finding the Emitted Power Per Square Meter for a Blackbody

To find the emitted power per square meter (intensity) of peak intensity for an object with a temperature of 2600 K, we will use the Stefan-Boltzmann law, which expresses the power radiated per unit area from a blackbody in terms of the Stefan-Boltzmann constant (σ) and the absolute temperature (T) to the fourth power. The Stefan-Boltzmann law can be written as:

dP/dA = σ T^4,

where σ (Stefan-Boltzmann constant) is approximately 5.67 × 10^-8 W/m^2/K^4. We can calculate the power per square meter by plugging the given temperature into this equation:

dP/dA = (5.67 × 10^-8 W/m^2/K^4) × (2600 K)^4,

After calculating, we find that the power emitted per square meter at peak intensity is:

dP/dA = about 1.53 × 10^7 W/m^2.

Therefore, an object at 2600 K emits approximately 1.53 × 10^7 watts per square meter.

When energy is added to an electron, it gets excited and jumps to a higher energy level. The electron, while in the excited state, is unstable and usually returns to its lower energy level, emitting energy as light. Line spectra observed in elements are based on this phenomenon.

When energy is added to an electron, what happens is termed as excitation. This means that the electron absorbs the energy and jumps from its initial energy level (or orbital) to a higher energy level. The electron, in the excited state, is unstable and usually falls back to its lower energy level or ground state, by emitting energy in the form of light.

The more energy supplied, the farther the electron is likely to jump. This phenomenon is the basis of the line spectra observed in elements. Each element has a unique number of electrons and energy levels resulting in a unique line spectrum.

The change in mechanical energy of the bullet is 3750 J. The magnitude of the average force from the wall stopping it is 1250 N.

(a) The change in mechanical energy of the bullet can be calculated by finding the initial mechanical energy and subtracting the final mechanical energy. Mechanical energy is the sum of kinetic energy and potential energy. Since the bullet comes to a stop, its final kinetic energy is zero. Therefore, the change in mechanical energy is equal to the initial kinetic energy of the bullet. The initial kinetic energy can be calculated using the formula KE = 1/2mv^2, where m is the mass of the bullet (30 g = 0.03 kg) and v is the velocity of the bullet (500 m/s). Plugging in the values:

KE = 1/2(0.03 kg)(500 m/s)^2

KE = 1/2(0.03 kg)(250000 m^2/s^2)

KE = 3750 J

Therefore, the change in mechanical energy of the bullet is 3750 J.

(b) The magnitude of the average force exerted by the wall on the bullet can be calculated using the formula for impulse. Impulse is equal to the change in momentum, and momentum is equal to the product of mass and velocity. Therefore, the equation is:

Impulse = Change in momentum = Force * Time

Since the bullet comes to a stop, its initial momentum is equal to its final momentum, which is zero. Therefore, the impulse is equal to the initial momentum. The initial momentum can be calculated using the formula momentum = mv:

Momentum = (0.03 kg)(500 m/s) = 15 kg*m/s

Now, we can calculate the average force using the equation Impulse = Force * Time:

15 kg*m/s = Force * (12 cm / 100 m)

Force = (15 kg*m/s) / (12 cm / 100 m) = 1250 N

Therefore, the magnitude of the average force from the wall stopping the bullet is 1250 N.

When the angle of the kick is changed, the range or distance the football travels will also change. To determine the new range when the angle is changed to 35.0°, calculate the horizontal component of the velocity and find the time it takes for the football to reach the ground. Multiply the time by the horizontal velocity to get the new range.

When the football is kicked at a different angle, the range or distance it travels will change. In this case, the original angle of 25.0° resulted in a range of 15.1 m. If the angle is changed to 35.0°, the range will be different. To find the new range, you can use the same initial velocity of 13.9 m/s and apply the new angle of 35.0°. Calculate the horizontal component of the velocity by multiplying the initial velocity by the cosine of the angle. Then use this new horizontal velocity and the initial vertical velocity to calculate the time it takes for the football to reach the ground. Finally, multiply the time by the horizontal velocity to find the new range.

Final answer:

To find how far the camel is from oasis B after walking 24 km at 19° south of east and then 4 km due north, we use vector components and the Pythagorean theorem.

Explanation:

The problem you're working on is a classic example of vector addition and applying principles of trigonometry to solve for the resultant displacement. The camel starts at oasis A, walks 24 km at a 19° angle south of east, and then walks 4.0 km due north. We're looking to find the distance the camel is from oasis B.

First, we break down the camel's walk into components. The eastward component of the first walk is 24 km × cos(19°), and the southward component is 24 km × sin(19°). After the camel walks 4 km due north, the total southward displacement would be reduced by 4 km. Given that oasis B is due east of oasis A, the eastward component is compared to the 25 km distance between the oases.

To find out how far the camel is from oasis B, we calculate the straight-line distance using the Pythagorean theorem: √((25 km - eastward component)² + (southward component - 4 km)²). Let's calculate these components and solve for the distance.

The eastward component is 24 km × cos(19°) and the reduced southward component is 24 km × sin(19°) - 4 km. Finally, calculate the distance from oasis B using the Pythagorean theorem with the adjusted components.

Final answer:

The roller coaster with an initial speed of 15 meters per second and decelerating uniformly at 7.0 meters per second² travels approximately 16.07 meters before it comes to a full stop.

Explanation:

To find out how far the roller coaster travels during its deceleration, we can use the formula derived from the equations of motion for uniformly accelerated motion (or deceleration in this case):

d = v2 / (2 * a)

Here, d is the distance traveled, v is the initial speed, and a is the deceleration.

Given that the initial speed (v) of the roller coaster is 15 meters per second and the deceleration (a) is 7.0 meters per second2, we can plug these values into the formula:

d = (15 m/s)2 / (2 * 7.0 m/s2)

d = 225 m2/s2 / 14 m/s2

d = 16.07 meters

Therefore, the roller coaster travels approximately 16.07 meters during its deceleration to a full stop.

This problem is a Pythagorean theorem problem. Pam's journey takes her 25 miles east and 45 miles north from her starting point, creating a right angle triangle with the point Paris. The shortest distance from Paris can thus be calculated with the Pythagorean theorem, yielding the result of approximately 45.276 miles.

To solve this, you need to recognize that this is a pythagorean theorem problem where you are looking for the shortest distance from Paris to the train as it travels from Rome to Florence. Initially, Rome is 30 miles west of Paris. When Pam travels to Florence, she goes 25 miles east (towards Paris) and 45 miles north.

Considering these overall movements, Pam has effectively moved 5 miles east and 45 miles north from Paris. You can imagine this as a right-angled triangle, where the base is 5 miles (east), the height is 45 miles (north), and the distance from Paris to the train is the hypotenuse.

We then apply Pythagoras' theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides to find the hypotenuse.

Using Pythagoras’ theorem: c² = a² + b², where 'a' and 'b' are the two shorter sides and 'c' is the hypotenuse (the distance we’re looking to find), we can calculate the shortest distance a² = 5² = 25 and b² = 45² = 2025. Thus, c² = 25 + 2025 = 2050, so c ≈ √2050 = 45.276. Hence, the closest distance that Pam gets to Paris is approximately 45.276 miles.

The force of tension acting on the elevator is calculated using Newton's second law of motion, considering the elevator's weight and its downward acceleration. After computations, the tension force is found to be approximately 15,150 N.

To determine the tension force (Ft) acting on the elevator, we can use Newton's second law of motion, which states that the force is equal to mass times acceleration (F = ma). First, we need to find the mass (m) of the elevator by using the weight (W) of the elevator and the acceleration due to gravity (g), which is approximately 9.81 m/s²:

m = W / g

Therefore, m = 14,700 N / 9.81 m/s² ≈ 1500 kg.

The net force acting on the elevator (Fnet) involves both its weight and the force of tension in the supporting cable, while considering the elevator's downward acceleration:

Fnet = Ft - W = ma

where 'a' is the acceleration of the elevator. Substituting the given values:

Fnet = Ft - 14,700 N = 1500 kg × (-0.30 m/s²)

Ft = 14,700 N + (1500 kg × 0.30 m/s²)

Calculating the terms:

Ft = 14,700 N + 450 N

Ft ≈ 15,150 N.

Therefore, to the nearest whole number, the force of tension acting on the elevator is 15,150 N.

Oxygen is more reactive than nitrogen. Because triple bond between two atoms of nitrogen and there is double bond between two atoms of oxygen.Therefore, this statement is true.

Reactivity is a substance's capacity to chemically react with other compounds. Iron, for instance, reacts vigorously with oxygen. Rust is a reddish powder that is created when it reacts with oxygen.

Because nitrogen has a higher dissociation energy than oxygen, its reactivity is lower than that of oxygen at the molecular level. Due to the triple bond that exists between the nitrogen atoms, the bond length of nitrogen is also shorter than that of oxygen.

Due to the strong triple bond between the atoms, the fact that all the valence electrons are in bonding orbitals, and the fact that more energy is required to excite them, Nitrogen is less reactive than Oxygen in the majority of gaseous processes.

Thus, Oxygen is more reactive than nitrogen.
