What is the derivative of y = x^2 or the change of y to the change in x.
Use the power rule which would give 2x as the derivative of y = x^2.

The current through a 1 ohm resistor is 1 amp. What is the voltage across the resistor ?
We will use Ohms law here which is V=IR. So 1 volt = 1 amp* 1 ohm
What would be the kinetic energy of a mass of 1 kg moving at a speed of 1 m/s ?
Kinetic energy is 1/2 * mass * magnitude of velocity squared. So it would 1/2*1 * 1 ^2 = 1/2 jouls
needs and Scott will reply soon.
