The cuboid and the cube below are placed on the floor. The cuboid has a weight of 60N and the cube has a weight of 40N. Which exerts a greater pressure on the ground? Prove your answer.

Hello. You forgot to put the image that shows information needed to answer that question. The image is attached below:

The cuboid and the cube exert the same pressure on the floor.

Explanation:

To answer this question, we must first consider that the area of the cuboid is equal to 24cm^2, while the area of the cube is equal to 16cm^2.

With that, we must calculate the pressure that each exerts, with the formula:

P = F / A

Cuboid: P = 60 / 0.0024 = 25000 N/m^2

Cube: P = 40 / 0.0016 = 25000 N/m^2

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 .

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
