Question

3. Рассчитать давление, производимое телом, масса которого 75 кг, а площадь опоры 15 м2 і балл 1 подскажите пожалуйста.​

Answer 1

P=F/s=75*10/15=750H/15м2= 50 Па

Answer 2

Calculating Pressure Exerted by the Body

To calculate the pressure exerted by a body, we can use the formula:

Pressure (P) = Force (F) / Area (A)

Where: - Force (F) is the weight of the body, which can be calculated using the formula: Weight = Mass × Acceleration due to gravity - Area (A) is the area of contact or support

Given: - Mass (m) = 75 kg - Area of support (A) = 15 m²

First, we need to calculate the force exerted by the body due to its weight.

Calculating Force (Weight)

The weight of the body can be calculated using the formula: Weight = Mass × Acceleration due to gravity

The standard acceleration due to gravity is approximately 9.81 m/s².

So, the weight of the body is: Weight = 75 kg × 9.81 m/s²

Now, we can calculate the pressure exerted by the body using the formula for pressure.

Calculating Pressure

Pressure (P) = Force (Weight) / Area

Substitute the calculated weight and the given area into the formula to find the pressure exerted by the body.
