Question

Найти давление р бруска массой 3 кг на стол если площадьоснования бруска 0.02М^2

Answer 1

M=3 кг
S=0,02 м²
g=10 H/кг
р-?

р=F/S=mg/S=3*10/0,02=1500 Па

ответ: р = 1500 Па

Answer 2

Calculating Pressure Exerted by a 3kg Block

To calculate the pressure exerted by a 3kg block on a table, we can use the formula:

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

Where: - Force (F) is the weight of the block, which is equal to its mass multiplied by the acceleration due to gravity (9.81 m/s^2). - Area (A) is the area of the block's base.

Calculation

Given: - Mass of the block = 3 kg - Area of the block's base = 0.02 m^2

First, let's calculate the force exerted by the block on the table: Force (F) = Mass (m) x Acceleration due to gravity (g)

Force (F) = 3 kg x 9.81 m/s^2

Force (F) = 29.43 N

Now, we can calculate the pressure: Pressure (P) = Force (F) / Area (A)

Pressure (P) = 29.43 N / 0.02 m^2

Pressure (P) = 1471.5 Pa

So, the pressure exerted by the 3kg block on the table is 1471.5 Pascal.
