Question

Помогите срочно пожалуйста!!!челове стоит на плоском щите лежалем на полу и производит давление на пол равное 125 Па каковы вес и масса щита с человеком если его площядь 4 м2

Answer 1

Ответ: вес — 500Н, масса — 50кг

Объяснение:

p=F/S, F=S*p=125*4=500H; F=mg=P=500H; m=P/g=500/10=50кг

Answer 2

Calculating the Weight and Mass of the Shield with a Person

To calculate the weight and mass of the shield with a person standing on it, we can use the formula for pressure, which is:

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

Given: - Pressure (P) = 125 Pa - Area (A) = 4 m^2

We can rearrange the formula to solve for force (weight):

Force (F) = Pressure (P) × Area (A)

Let's calculate the force (weight) first.

Force (F) = 125 Pa × 4 m^2 Force (F) = 500 N

So, the force (weight) exerted by the person and the shield on the floor is 500 N.

Calculating the Mass

To calculate the mass, we can use the formula:

Weight (W) = Mass (m) × Acceleration due to gravity (g)

Given: - Weight (W) = 500 N - Acceleration due to gravity (g) = 9.81 m/s^2 (standard value)

We can rearrange the formula to solve for mass:

Mass (m) = Weight (W) / Acceleration due to gravity (g)

Let's calculate the mass using the given weight and the standard value of acceleration due to gravity.

Mass (m) = 500 N / 9.81 m/s^2 Mass (m) ≈ 51.02 kg

So, the mass of the shield with the person standing on it is approximately 51.02 kg.
