<span>It uses chemical and kinetic energy</span>
<span>Well the Wheels would help to move the box but you need to have in mind that if the box is heavy you must make sure that it does not role-down because of how heavy the box is</span>
Answer:
The wind spins blades of a wind turbine around a rotor, which spins a generator, which creates electricity (a generator converts mechanical energy into electricity).
Answer:
0.1164 m
0.49387 m
Explanation:
m = Mass = 5 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height from which brick falls = 12 m
k = Spring constant = 8 kN/m
a) Potential energy of the brick

Potential energy in spring

The compression of spring = 0.5-0.3836 = 0.1164 m
b) Weight of the brick


The final length of the spring = 0.5-0.00613 = 0.49387 m
