Let r1 be the distance from the Earth to the point where

the gravitational accelerations are the same and let r2 be the distance

from the Moon to that point.

Then, r1+ r2 = r12 = 383,000 km.

Let Re be the radius of earth

and let Rm be the radius of moon

Let, ge be the gravity of earth

and let gm be the gravity of moon

The fact that the gravitational attractions by the Earth and the Moon

at this point are equal leads to the equation

gE(Re/r1)=gM(Rm/r2)

9.8(6380/r1)=1.62(1738/r12-r1)              

(here, Re=6380, gE=9.8m/s^2,  gM=1.62m/s^2 and r12=383,000 km

9.8*6380/(1.62*1738)=r1/(383000-r1)

therefore,

r1=344,770 km

Explanation:

By width, we commonly mean the diameter of the pipe. Before, giving some logical examples we will look at the scientific proof of this fact. There was a physicist named Jean Leonard who experimented on fluid flow during the start of 19th century,  He deduced the results as  the flow rate is proportional to the fourth power of pipe radius,

His results can mathematically be expressed as :

Volume flow rate = π X pressure difference X pipe radius 4 X liquid viscosity / 8 X viscosity X pipe length.

Now let us take an example which shows how pipe diameter or radius (half of diameter) affect the flow of water.

Lets suppose we have a pipe that has radius of 2 inches and length of 6 and we want to calculate that what will be the the flow rate if we increase the length of pipe from 2 to 4 inches. When the length is constant, the radius has also got changed by 2 inches.

So, if we assume that temperature, pressure and length is constant and no external factor is affecting the water flow, then according to above equation  the flow rate will change by a factor of 24, or 16.

This shows that the width or radius influence flow rate of water.

                                                                                 = 65000 J

  efficiency (η) = work done by the machine ÷ work supplied to the machine

               0.65 =  65000 ÷ Input work

The potential energy of a 1,300 kg car at the edge of a cliff 1,500 m high would be approximately 19,094,500 Joules or 19.1 MJ. This calculation utilizes the formula for potential energy, PE = m*g*h.

The calculation of Potential Energy is based on the formula PE = m*g*h. In this formula, 'm' represents the mass of the object, 'g' stands for the gravitational force (approximately 9.81 m/s² on Earth), and 'h' indicates the height above the ground. For a car with a mass of 1,300 kg at the edge of a cliff 1,500 m above the ground, the calculation would look like this.

PE = 1,300 kg * 9.81 m/s² * 1,500 m

This results in a potential energy of approximately 19,094,500 Joules, or 19.1 MJ. This amount of energy would be converted to kinetic energy if the car were to fall from the cliff, assuming no other energies are involved (like air resistance or friction).

The potential energy of a 1,300 kg car at the edge of a cliff 1,500 m above the ground is approximately 19,108,500 Joules. The calculation uses the formula PE = mgh. Substituting the given values into the formula provides this result.

Potential energy due to gravity is given by the formula:

PE = mgh

where:

m = mass of the object (1,300 kg)

g = acceleration due to gravity (9.81 m/s²)

h = height above the ground (1,500 m)

Now, substituting these values into the formula:

PE = 1300 kg x 9.81 m/s² x 1500 m

PE ≈ 19,108,500 Joules

Hence, the potential energy of the car is approximately 19,108,500 Joules.

a)

Y₀ = initial position of the stone at the time of launch = 0 m

Y = final position of stone = 20.0 meters

a = acceleration = - 9.8 m/s²

v₀ = initial speed of stone at the time of launch = 30.0 m/s

v = final speed = ?

Using the equation

v² = v₀² + 2 a (Y - Y₀)

inserting the values

v² = 30² + 2 (- 9.8) (20 - 0)

v = 22.5 m/s

b)

Y₀ = initial position of the stone at the time of launch = 0 m

Y = maximum height gained

a = acceleration = - 9.8 m/s²

v₀ = initial speed of stone at the time of launch = 30.0 m/s

v = final speed = 0 m/s

Using the equation

v² = v₀² + 2 a (Y - Y₀)

inserting the values

0² = 30² + 2 (- 9.8) (Y - 0)

Y = 46 m

(a)The speed of the stone when it reaches [tex]20.0 m[/tex] is approximately [tex]22.5 m/s[/tex]

(b)The maximum height it reaches is approximately [tex]45.9 m[/tex].

Let's analyze the motion of the stone in two parts: finding its speed at a height of 20.0 meters and its maximum height.

(a) Speed at [tex]20.0 m[/tex]

We can use the following kinematic equation:

[tex]v^2 = u^2 + 2as[/tex]

Initial speed [tex]u = 30.0 \, \text{m/s}[/tex]

Acceleration [tex]a = -9.8 \, \text{m/s}^2[/tex] (since gravity acts downwards)

Displacement [tex]s = 20.0 \, \text{meters}[/tex] (upward positive)

Substituting in the given values:

[tex]v^2 = 30.0^2 + 2(-9.8)(20.0)\\\\v^2 = 900 - 392\\\\v^2 = 508[/tex]

Hence:

[tex]v = \sqrt{508} \approx 22.5 \, \text{m/s}[/tex]

(b) Maximum Height

At maximum height, the speed ([tex]v[/tex]) will be 0. Using the same kinematic equation:

[tex]0 = 30.0^2 + 2(-9.8)s0 = 900 - 19.6s[/tex]

Solving for [tex]s[/tex]:

[tex]s = \frac{900}{19.6} \approx 45.9 \, \text{meters}[/tex]

Thus, the highest point the stone may reach is roughly [tex]45.9 m[/tex].

We know that, Power is defined as rate of doing work

Power = Work ÷ time  Watts,

Given ; Force = 200 N

            Distance = 25 m , and time (t) = 10 s.

            First determine the work, Work = Force × distance

                                                                 = 200 ×  25

                                                             W = 5000 J

            Now, Power =  5000 ÷ 10

                                 = 500 W

Given data

mass (m) = 13 kg

             F₁ = 13 × 9.8 = 127.4 N

air resistance (F₂ ) = 9 N, acts in opposite direction

            Net force is defined as sum of all forces

              Fnet = F₁ - F₂

                       = 127.4 - 9

                       = 118.4 N

Net force acting on the object is 118.4 N

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Answer:

Discovered by Sir Isaac Newton, this law states that every object in the universe that has mass attracts every other object in the universe that has mass. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between their centers. When applying this to a situation with two objects, the object with the smaller mass will do most of the moving because the other object has too much inertia to move any noticeable amount.

D. The mass number

Explanation:

Isotopes are defined for same atoms

If an atom has same number of protons and same number of electrons but different number of neutrons in it then such pair of atoms is known as isotopes

so we have

same atomic number in all isotopes

since atomic number is same so we can say that total charge of the two atoms must be same

So we will say that since number of neutrons is different in isotopes to sum of neutrons and protons which is known as mass number is different in such pair of atoms

So correct answer is

D. The mass number

The property of the isotopes must be different in "The mass number." The correct answer is D.

Isotopes are atoms of the same element that have the same atomic number (A) and number of protons in their nucleus, but they have different mass numbers (Z). The mass number represents the total number of protons and neutrons in an atom's nucleus. Isotopes of an element have the same number of protons but different numbers of neutrons, which results in different mass numbers.

Let's examine why the other options are not true:

A. The atomic number: The atomic number represents the number of protons in an atom's nucleus. Isotopes of the same element have the same atomic number because they have the same number of protons. So, the atomic number remains constant for isotopes.

B. The electric charge: Electric charge refers to the imbalance of electrons and protons in an atom, which determines its overall charge. Isotopes of the same element have the same number of protons and electrons, thus maintaining the same electric charge.

C. The element name: The element name represents a specific type of atom characterized by a unique number of protons in its nucleus. Isotopes of the same element have the same number of protons, so they share the same element name. The element name does not change for isotopes.

Therefore, the property that must be different for isotopes is the mass number (D).

Lithium fluoride is created due to the increased stability in the completion of fluorine's outer shell. By moving one electron from lithium, its outer shell is now full (with two). Additionally, by adding this electron to fluorine, it gains a full, stable octet.

The formation of lithium fluoride (seen here) is due to the increased stability in the completion of fluorine's outer shell, therefore the correct answer is option B.

The octet rule is the rule that explains that an atom should have filled with eight electrons in its valence shell for the most stable state.

For example, an Oxygen atom that has six electrons in the outermost shell needs two more electrons in its valence shell to form a stable atom.

In the formation of the lithium fluoride the lithium atom which has an extra electron in its outermost shell transfer it to the fluorine atom which has one less electron in its outermost shell so that it can compete with its octet.

The bond formed between the lithium and the fluorine atoms in the lithium fluoride is of an ionic nature where one electropositive and one electronegative atom are involved and the bond is formed by the transfer of the electron.

thus, The formation of lithium fluoride is because of the increased stability in the completion of fluorine's outer shell, therefore the correct answer is option B.

Hurricanes gain strength by using warm ocean waters as their primary energy source. The warm water evaporates and condenses, releasing latent heat, fueling the storm's intensification and driving its powerful winds.

Warm ocean waters and favourable atmospheric conditions strengthen hurricanes. Latent heat from warm, moist ocean air rising and condensing into clouds and rain powers them. Latent heat release fuels the storm. Warm, wet air rises, lowering surface pressure. Air fills this low-pressure area, rotating and organising the storm. The Coriolis effect, induced by Earth's rotation, spins the storm, strengthening it.

Hurricanes need low vertical wind shear, which limits wind speed and direction with height. Low wind shear lets the storm intensify vertically. Hurricanes receive energy from warm ocean waters, latent heat release, minimal wind shear, and the Coriolis effect.

Answer:

Option (2)

Explanation:

The earth is comprised of denser materials such as iron and nickel and other siderophile elements in the core and silicate materials in the mantle. The temperature at the core of the earth is extremely high that generates a force, that allows the molten materials (magma) to rise up from the bottom of the mantle towards the crust, in the form of convection currents. This upward movement of magma forces the lithospheric plates to move.

Thus, magma rises from the bottom of the mantle towards the crust.

Hence, the correct answer is option (2).

The fastest in speed of sound is steel. The slowest in speed of sound is oxygen. Hope this helped! I don't really know how to answer this but by looking at the table it looks like this can be one of the conclusions.

The measurements in the table allow for the following conclusion: Stiff and dense materials like steel and granite allow sound to propagate extremely fast (5-6 km/s) while lower density ones, like the fluids, reduce this speed to about 1.5km/s, with the lowest-density media (gases) allowing for only order of hundreds of m/s.

The measurements are consistent with a model of energy propagation consisting of spheres (modeling the molecules) and springs connecting them (modeling the molecular bonds). It can be shown that the mass of the spheres and the stiffness of the springs are factors in speed of energy propagation.
