Answer:
36.28 kg
Explanation:
Given data:
Gravitational potential energy of object = 800 J
Height from ground = 2.245 m
Mass of object = ?
Solution:
Formula:
P.E = mgh
g =acceleration due to gravity = 9.8 m/s²
by putting values,
800 J = m× 9.8 m/s² ×2.25 m
J = kgm²/s²
800 kgm²/s² = m× 22.05 m²/s²
m = 800 kgm²/s² /22.05 m²/s²
m = 36.28 kg
False .........................................
An earthquake's magnitude is a measure of how much energy an earthquake releases. Typically, the richter scale is used.
Yes, this is balanced. Each part of the substance (like Mg) has the same number on both sides.
Hope this helps you:)
