Why do you suppose we minimized the sum of the squares of the residuals in the "falling bodies" lab rather than just minimizing the sum of the residuals without squaring? (in our case the residual is the "y" distance from o data point to the fit curve).

Distinguish between a transverse wave and a longitudinal wave.

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.

What are the north and south poles of a solenoid change with?
