Question

When a car makes a turn, the centripetal force is provided by: Gravity Friction Normal force No centripetal force is needed Which of these quantities does NOT affect the torque created by a force? The magnitude of the force Where the force is applied The direction of the force All of these affect the torque While standing on Earth, how large is the gravitational force on a 7-kg object due t the Moon? The mass of the Moon is 7.35 x 10^22 kg and the distance from the Earth to the Moot is 3.82 x 10^8 m. 2.4 x 10^-1 N 2.4 x 10^-3 N 2.4 x 10^-2 N 2.4 x 10^-4 N In the International Space Station which orbits Earth, astronauts experience apparent weightlessness because: The astronauts are in free fall There is no gravity in space The radiation shields block gravity The station is so far away from Earth.

Explanation / Answer

1) option b) is correct. as centripetal force is based on the law of inertia.

2) option d) is correct.

3) option d) is correct.

Force = GmM/r^2 = (6.67*10^-11*7.35*10^22*7)/(3.82*10^8)^2 = 2.4*10^-4 N

4) option a) is correct.
