Acarpenter hits a nail with a hammer. compared to the magnitude of the force the hammer exerts on the nail, the magnitude of the force the nail exerts on the hammer during contact is?

Equal (and the direction is opposite)

Explanation:

Newton's third law of motion states that:

"when an object A exerts a force on an object B, object B exerts an equal and opposite force on object A. The two forces are called action and reaction"

In this situation, we have a hammer exerting a force on a nail. We can think the hammer as object A and the nail as object B, so according to Newton's third law, the nail must exert an equal and opposite force on the hammer.

Therefore, the magnitude of the force that the nail exerts on the hammer is equal to the force exerted by the hammer on the nail (and in opposite direction)

d

explanation:

i think the answer is d. but im not sure!

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 .
