Answer 2

Calculation of Pressure

To determine the pressure exerted by the marble slab on the ground, we can use the formula:

Pressure = Force / Area

In this case, the force is equal to the weight of the marble slab, and the area is the contact area between the slab and the ground.

Given: - Mass of the slab = 2700 kg - Length of the edge in contact with the ground = 10 m - Width of the edge in contact with the ground = 5 m

To calculate the force, we can use the formula:

Force = Mass x Acceleration due to gravity

The acceleration due to gravity is approximately 9.8 m/s^2.

Let's calculate the force first:

Force = 2700 kg x 9.8 m/s^2

Using a calculator, we find that the force is approximately 26,460 N (Newtons).

Next, let's calculate the contact area between the slab and the ground:

Area = Length x Width

Area = 10 m x 5 m

The area is 50 square meters.

Now we can calculate the pressure:

Pressure = Force / Area

Pressure = 26,460 N / 50 m^2

Using a calculator, we find that the pressure exerted by the marble slab on the ground is approximately 529.2 N/m^2 (or Pascal).

Therefore, the pressure exerted by the marble slab on the ground is approximately 529.2 Pascal.
