Answer:
Explanation:
1. The gravitational force is related to the mass of each object.
This is true, the gravitational force between the two objects is directly proportional to the product of masses of two objects.
2. The gravitational force on a satellite is less at an altitude of 500 km above the Earth than at an altitude of 1000 km.
It is false, as the gravitational force between two objects is inversely proportional to the square of distance between them. The objects at more height has less gravitational force.
3. The gravitational force between the Earth and a person is constant, no matter how high the person is above the surface of the Earth.
It is false, because as we go on heights the value of acceleration due to gravity decreases.

This can be seen through the fact that Aksionov has the ability to seek his own justice many times throughout the story, yet does not take it
Answer:
7.01yard/sec
Explanation:
Given parameters:
Initial position = 50yard
Final position = 12yard
Time = 5.42s
Unknown:
Average speed of runner = ?
Solution:
To solve this problem;
Speed =
Distance covered = Initial position - final position = 50 - 12 = 38yards
So;
Speed = = 7.01yard/sec
