Question

Определите потенциальную энергию каждой тонны, падающей с высоты80 м воды на Мингячевирской гидроэлектростанции.

Answer 1

Епотенциальная=mgh=10³*10*80=800 000Дж=800Кдж

Answer 2

Calculation of Potential Energy

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

Potential Energy = mass × gravitational acceleration × height

In this case, we need to determine the potential energy of each ton of water falling from a height of 80 meters at the Mingachevir Hydroelectric Power Station.

Given: - Height (h) = 80 meters - Mass (m) = 1 ton = 1000 kg (since 1 ton is equal to 1000 kilograms) - Gravitational acceleration (g) = 9.8 m/s^2 (approximately)

Using the formula, we can calculate the potential energy:

Potential Energy = 1000 kg × 9.8 m/s^2 × 80 meters

Calculating the potential energy:

Potential Energy = 784,000 joules

Therefore, each ton of water falling from a height of 80 meters at the Mingachevir Hydroelectric Power Station has a potential energy of 784,000 joules
