When a pan turns warm after touching the hot stove, what kind of energy is transferred?
Conduction
number of sound waves that pass in a certain amount of time
frequency

A stretched rubberband
Potential
Name one object that can act like a prism.
Mirror, water, raindrop
Does a sound with a very low pitch have a high frequency or a low frequency?
low pitch = low frequency

Explain how a grandfather clock shows potential and kinetic energy
When the pendulum is out to the side it is potential energy, as it swings down it is moving and kinetic energy, and when its through to the other side it is potential energy again.
If you want to stay cool playing outside on a sunny day, which is better to wear? and WHY?
A black t-shirt
A white t-shirt
A white t-shirt because a black t-shirt absorbs all of the visible colors and it turns to thermal energy you feel warmer. A white shirt does not absorb light.
The measure of a sound wave from the midline
amplitude
How does food get hot in a frying pan? EXPLAIN
Conduction- when the hot stove touches the pan it transfers heat through conduction.
