Question

2. Определить, с какой силой оса вонзает свое жало в кожу человека, если площадь острия жала равна 3*10-16 м2, а производимое им давление составляет 3*1010 Па.

Answer 1

F=P*S=3*10^10*3*10^-16=9*10^-6 H

Answer 2

Calculating the Force of a Bee Sting

To calculate the force with which a bee stings a person, we can use the formula:

Force = Pressure × Area

Given: - Area of the bee's stinger (A) = 3 × 10^-16 m^2 - Pressure exerted by the stinger (P) = 3 × 10^10 Pa

Calculating the Force

Using the formula, we can calculate the force exerted by the bee's stinger:

Force = 3 × 10^10 Pa × 3 × 10^-16 m^2

Force = 9 × 10^-6 N

So, the force with which the bee stings a person is approximately 9 × 10^-6 Newtons.
