-- heat the magnet red-hot in a flame
-- drop it on the floor several times, or beat it with a hammer
-- place it in a strong, rapidly alternating external magnetic field
Answer:
Gravitational energy
Explanation:
when over head , when it hits the floor thermal energy
The wise and careful use of energy is called CONSERVATION
The impact of the material
type with which the slope is made affects the acceleration. Acceleration will
be higher and smoother if the material of the slope surface is smoother as
opposed to a texture which is not smooth. Smoother surface allows more acceleration
because it will have less friction and resistance. Otherwise the friction will
slow the object down for example a grassy ground will have more friction than a
well maintained marble floor.
By calculating the crests, you can find the waves' frequency.
Hope this helps!
