Question

На вершине горы высота которой составляет 800 м нд уровнем моря растёт яблоня. какова потенциальная энергия яблока массой 0,5 кг, весящего на ветке

Answer 1

E=mgh
E=0.5*10*800=4000Дж

Answer 2

Calculating Potential Energy of an Apple on a Tree

To calculate the potential energy of an apple hanging from a tree at the top of a mountain, we can use the formula for gravitational potential energy:

Gravitational Potential Energy (GPE) = mass * acceleration due to gravity * height

Given: - Height of the mountain top = 800 m - Mass of the apple = 0.5 kg - Acceleration due to gravity = 9.81 m/s^2 (standard value)

Calculation

Using the given values and the formula for gravitational potential energy, we can calculate the potential energy of the apple:

GPE = 0.5 kg * 9.81 m/s^2 * 800 m

GPE ≈ 3924 Joules

So, the potential energy of the apple, with a mass of 0.5 kg, hanging from a tree at the top of the 800 m high mountain, is approximately 3924 Joules.
