A.
different geographic regions on the earth
B.
the speed of revolution around the sun
C.
the location of all continents found on the earth
D.
the speed of rotation on its axis
The rock on the ground has more kinetic energy compared to the feather floating through the air, due to the force of gravity.
Kinetic energy is the energy of motion, and a moving object has kinetic energy. Potential energy, on the other hand, comes in several forms, such as gravitational potential energy. When comparing a feather floating through the air and a rock on the ground, we can say that the rock has more kinetic energy.
This is because the rock, when dropped, falls to the ground due to the force of gravity, gaining kinetic energy in the process. The feather, on the other hand, is floating through the air and not experiencing the same gravitational pull, thus having less kinetic energy than the rock.

Answer:
The correct answer is option B)
Explanation:
Considering the given question as -
The space shuttle is located exactly half way between the earth and the moon. Which statement is true regarding the gravitational pull on the shuttle? A) The moon pulls more on the shuttle. B) The earth pulls more on the shuttle. C) Both are equal due to equal distances. D) Both are equal due to the mass of the shuttle.
We know that gravitational pull (F) between any two bodies of mass and is given by -
F = where 'r' is the distance between the two bodies.
Let ,
: Mass of the earth
: Mass of the moon
m : Mass of the satellite
: Distance of satellite from earth
: Distance of satellite from moon
Given that =
Let ==r
Force on satellite by the earth is -
=
Force on satellite by the moon is -
=
∵ Mass of earth () > Mass of moon ()
∴ >
∴ The gravitational pull of earth on satellite is more than that of the moon.
