Abaseball is thrown a distance 0f 60 feet. what is its speed if it takes 0.5 seconds to cover the distance

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 .

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
