Kathy had a heavy metal ball and Rich had a light wooden ball. They dropped the balls from the same height. They were surprised to discover that the two balls reached the ground at the same time. This is what they said after the balls landed:

Kathy: "The force of gravity must be acting the same on both balls."

Rich: "I don’t agree. The metal ball weighs more, so the force of gravity is more on the heavier ball."

yes Rich is correct

Explanation: Becuase metal is heaveir than wood so the metal ball would have more gravit pulled on it .

Rich is correct

Explanation:

I agree with Rich because his wooden ball weighed less then Kathy’s metal ball so there was a greater gravitational pull on the metal ball.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
