One of the leading causes of hearing impairment that's due to damage
of the ear machinery is prolonged exposure to loud noise or loud music,
which damage the tiny hair cells that stimulate nerve endings in the inner ear.
Trust me.
What mass of water must fall 12m in order to lose 10,800J of gravitational potential energy ?
Potential energy = (mass) x (gravity) x (height)
10,800J = (mass) x (9.8 m/s²) x (12m)
Mass = (10,800J) / (9.8 m/s² x 12m)
Mass = (10,800 / 9.8 x 12) (Joule-sec²/m²)
(Units: Joule-sec²/m² = N-m-sec²/m² = (kg-m/s²)-m-sec²/m² = <u><em>kg </em></u>)
<u>Mass = 91.8 kg</u>
