A new planet has been discovered that has a mass one-ninth that of Earth and a radius that is half that of Earth. Determine the free fall acceleration on the surface of this planet. Express your answer in the appropriate mks units.

The free fall acceleration on the surface of this planet is 4.35 m/s²

Explanation:

Given that,

Mass of planet

Radius of planet

We need to calculate the free fall acceleration on the surface of this planet

Using formula of gravity

Where,   = mass of planet

= radius of plane

Put the value into the formula

Hence, The free fall acceleration on the surface of this planet is 4.35 m/s²

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

what is the actual question though?
