Answer: Gravity causes a change in the mass of objects on earth and the moon.
Explanation:
Because of gravity, the weight of objects lessen, and decrease because of gravity. If you were to drop an object from earth from space, the object would have more mass. Hope that helps.
Answer: 12 m/s
Explanation:
If we ignore air resistance, gravity alone will reduce the upward velocity to zero at the top of the flight. As gravity is a conservative force, it will return exactly the same amount of energy to the tennis ball when it returns to the original elevation.
Answer:

Explanation:
Given that,
Magnetic field, 
Acceleration of the electron, 
Speed of electron, 
The force due to this acceleration is balanced by the magnetic force as :




So, the angle between the electron's velocity and the magnetic field is 10.6 degrees. Hence, this is the required solution,
The woman weighs 100N now.
Explanation:
Given:
F is given as 400N
one full additional earth radius formed
To Find:
Weight of the woman=?
Solution:
We know that gravitational force is inversely proportional to the square of radius.

where
is the gravitational force
is the radius square
So when radius is doubled, the force becomes one fourth of the original.
Therefore
