Sound is an example of a longitudinal wave.
Resistance = (voltage) / (current)
For this piece of wire . . .
Resistance = (61 volts) / (6 Amperes)
Resistance = (61/6) (V/A)
<em>Resistance = (10 and 1/6) ohms</em>
Since you know the voltage and current, the length doesn't matter.
The answer is c cause it is not moving like the other 3
Pressure is defined as the force per unit area on a body.
The correct answer is #4. They have the same number of protons but a different number of neutrons.
