What is a long distance surface current?

Why is iron significant to understanding how a supernova occurs?

A stone is dropped from the upper observation deck of a tower, 950 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t.

The specific heat of copper is 0.093 cal/gC°, and the specific heat of aluminum is 0.22 cal/gC°. The same amount of energy applied to equal masses, say, 50.0 g of copper and aluminum, will result in a. a higher temperature for copper. b.

a man walks foward on a bus. to a stationary obserrver, the bus moves east at a speed of 18 m/s if the man moves 1.5 m/s wast relative to the bus. what is his velocity in the frame of reference of a stationary observer?

How does resistance affect the current in a circuit?

The period of a cepheid variable star and the time of one recent maximum can be used to predict the time of a future maximum. suppose that you calculate the time of future maximum brightness and then make measurements to observe this maximum.

An Ohmic material is one in which its resistance does not depend on the voltage across it or the current within it. In that case, the resistance does NOT depend on:

A concave lens is also called a diverging lens.

If one light bulb is removed from a parallel circuit with three bulbs, the brightness of the other bulbs will decrease.
