Answer:
Radius in mm will be 4.425 mm
Explanation:
We have given given escape speed of earth is equal to speed of the light as
Gravitational constant
Mass of the earth
We have to find the radius of the earth
We know that escape speed is
So
Squaring both side
So radius in mm will be 4.425 mm

Answer:
i. Geodynamo
ii. Gravitational energy conversion
Explanation:
The outer core of the Earth is believed to be in molten form, consisting of mainly iron and nickel. The reaction (mixture) between these components or elements generates conventional currents which is maintained by the gravitational energy produced in the process. Thus, magnetic fields are generated continuously due to the continuous flow of electric current during the processes.
The building is in solid phase. Its molecules are arranged in a ver compact manner that is why it takes a definite shape and volume. When it is heated, the kinetic energy of the molecules increases. This is characterized by more frequent collisions. The rise in temperature causes the molecules to move rapidly by vibrating. When it reaches an amount of energy that causes the solid to change phase, this is called the latent energy. The molecules break their form and move farther away from each other until it resembles that of a liquid melting. This phase change is known as melting. The energy that must be reached to achieve melting is the latent heat of fusion.
