Question

2. Чему равна потенциальная энергия люстры массой 2650 г, находящейся на потолке на высоте 3 м?​

Answer 1

Ответ:                                                    Решение:  

дано:                                              Ep=mgh;

m=2650 г=26,5 кг                       Ep=26,5кг * 3м=79, 5 Дж

h=3 м

Найти:                                            ответ: Ер=79,5 Дж

Ep-?

Answer 2

Calculation of Potential Energy

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

Potential Energy = mass * gravity * height

In this case, the mass of the chandelier is given as 2650 grams, and it is located at a height of 3 meters from the ceiling.

Let's calculate the potential energy:

Potential Energy = 2650 grams * 9.8 m/s^2 * 3 meters

Converting grams to kilograms:

Potential Energy = 2.65 kilograms * 9.8 m/s^2 * 3 meters

Calculating the potential energy:

Potential Energy = 77.49 joules

Therefore, the potential energy of the chandelier with a mass of 2650 grams, located at a height of 3 meters, is approximately 77.49 joules.
