1) An astronaut awakes in her closed capsule, which actually sits on the Moon. Can she tell whether her weight is the result of gravitation or of accelerated motion? Explain. (10 points)
No, the Astronaut cannot tell whether h
er weight is because of accelerated motion of the gravitation because in case capsule didn’t land on moon and is not stationary with respect to moon even then she feels the same weight proportion and would be unable to tell whether the weight is because of accelerated motion or gravity. In general theory of relativity, the accelerated motion and gravitational force cannot be distinguished. Also by the equivalence principle, any effect produced by gravity can be easily replicated by accelerated motion and vice versa. Hence, it is not possible for her to tell the science behind her weight in her closed capsule. It is the fact that person inside closed container cannot conclude whether acceleration is due to exhibition of container are different gravitational prisons or doodles as such.
For her to realize the force of accelerated motion or gravity, capsule needs to be of constant acceleration so as to move without being noticed. However, in case the capsule slows down, there would be reduction in speed and chances of seeing gravitational effects are there. Also, there is another way that is for capsule to spin constantly and have accelerated motion of outwards direction to make her feel the weight as capsule would have been of small size creating a strong gravity feel.
2) Do you age faster at the top of a mountain or at the mountain’s base? Explain. (10 points)
Yes, this is true that one age faster at top of mountain and age slowly at bottom. Einstein stayed off relativity and the relation between the time and gravitational acceleration is well known. This can help to simplify the gravitational acceleration. It is well known that gravitational field off is because of GM by our square where M stands for mass of earth and R is really support so at the bottom of mountain, the radius of earth from the center of earth to point where one’s feet are is measured that is on the surface which do have smaller value as compared to top of mountain. The value is larger if calculated from the top of mountain. Thus, force...
