Which action results from the combination of gravity and inertia working on the moon
2 answers:
Answer:
Revolution of moon around the earth
Explanation:
The revolution of moon around the earth.
The gravitational force acting on the moon is balanced by the centripetal force acting on the moon.
Gravitational force of earth on moon is given by
where, M be the mass of earth, m be the mass of moon and r be the distance between moon and earth.
The centripetal force acting on moon is
These two forces balance each other and then the moon revolves around the earth in fixed orbit.

c. 1600J
Explanation:
The loss in potential energy of the boy is given by:
where
m = 40 kg is the mass of the boy
g = 9.8 m/s^2 is the acceleration of gravity
is the total change in the height of the boy (4 metres + 2 cm due to the compression of the spring)
Substituting, we find
<h3>Compton scattering, discovered by Arthur Holly Compton, is the scattering of a photon after an interaction with a charged particle, usually an electron. If it results in a decrease in energy of the photon, it is called the Compton effect. Part of the energy of the photon is transferred to the recoiling electron.</h3>
