What would happen if earth shrunk to half its size?
If earth shrinks to half, then it can increase gravity on surface of earth. Hence, the weight of every person on earth will increase. Hence, its clear from this expression that gravity will increase and our weight too.
What happens if earth shrinks?
If the radius of earth shrinks by 1.5\% (mass remaining same), then the value of gravitational acceleration changes by. A. The earth becomes more compact that indicates that the gravitational force on the test mass will increase, and hence the acceleration due to gravity will also change.
What will happen to the duration of the day if earth contracts to half of its radius?
Time period of rotation of Earth is what we call a day. So, for an Earth that is contracted to half its present size with mass constant, the duration of a day will be just 6hrs.
Why is a black hole invisible?
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. Because no light can get out, people can’t see black holes. They are invisible.
How was the earth created NASA?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
When the earth suddenly shrinks to half of its present radius?
If the earth suddenly shrinks (without changing mass) to half of its present radius, then acceleration due to gravity will be. g=GMR2, If radius shrinks to half of its present value, then g will become four times.
What would be the length of the day if the earth were to shrink?
L=Iω=I2πT remains constant. As I decreases, T must decrease. Hence the length of the day will decrease.
When the earth shrinks without reducing its mass What changes will be there in the duration of a day?
Length of the day would become 6 hours. As size of earth changes its moment of inertia changes.
Is gravity a weight?
The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume.
What will be the value of G at the Centre of the earth?
The value of g at the centre of the earth is zero.
