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.

R=ρ
Where, R is resistance
ρ is resistivity,
L is length and
A is cross sectional area
Given, L= 3.5m
A=5.26 x 10⁻⁶ m²
ρ=1.68×10⁻⁸ ohms m
∴ R=
⇒ R=1.11×10⁻² ohms
