At some point during construction, the International Space Station had a mass of 235,565 kg. When it orbited the Earth at an altitude of 400,000 m,
what was the approximate gravitational force on the Station due to Earth's
gravity? (Recall that Earth has a radius of 6.37 * 106 m, it has a mass of 5.97
x 1024 kg, and G = 6.67 * 10-11 N·m²/kg?.)
A. 3.6 x 106 N
B. 3.1 x 106 N.
mm
C. 2.0 x 106N
D. 3.9 ~ 106 N

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

well clustered together.
