E=mgh

E=2*10*10=200

надежды правильно

Answer 2

Ответ:

Eп= mgh= 0,25 кг×10×12м=30 Джоулей

Answer 3

Calculation of Potential Energy

To calculate the potential energy of an object, we can use the formula:

Potential Energy = mass * gravity * height

Given that the mass of the ball is 250 grams (0.25 kg) and the height is 12 meters, we can calculate the potential energy as follows:

Potential Energy = 0.25 kg * 9.8 m/s^2 * 12 m

Let's calculate the potential energy:

Potential Energy = 0.25 kg * 9.8 m/s^2 * 12 m = 29.4 Joules

Therefore, the potential energy of the ball at a height of 12 meters is 29.4 Joules.
