Question

Эйфелева башня в Париже создает давление на грунт 20000 Па. Чему равна площадь опоры башни, если ее вес 90000000 Н?

Answer 1

Ответ:

4500м²

Объяснение:

Как много нулей. p = F/S, S = F/p

p = 20 * 10^3 Па

F = 90 * 10^6 Н

S = 90 * 10^6 / 20 * 10^3 = 4,5 * 10^3 м² = 4500м²

Answer 2

Calculation of the Area of the Tower's Base

To calculate the area of the base of the Eiffel Tower, we need to use the given information about the pressure exerted on the ground and the weight of the tower.

The pressure exerted on the ground by the tower is given as 20,000 Pa (Pascals), and the weight of the tower is given as 90,000,000 N (Newtons).

The formula to calculate pressure is:

Pressure = Force / Area

We can rearrange this formula to solve for the area:

Area = Force / Pressure

Substituting the given values into the formula:

Area = 90,000,000 N / 20,000 Pa

Calculating this:

Area = 4,500 square meters

Therefore, the area of the base of the Eiffel Tower is 4,500 square meters.
