A cell provides 6 V to an LDR. The current through this LDR is measured and is found to be 3 A. What is the resistance of the LDR?

An object is dropped and falls freely to the ground with an acceleration of g. If it is thrown upward at an angle instead, its acceleration would be:

Simplify completely: - 3 (4-9) + 6-2 (-8+5)

Suppose you read in the newspaper that a new planet has been found. Its average speed in its orbit is 33 kilometers per second (km/s). When it is closest to its star, it moves at 31 km/s, and when it is farthest from its star, it moves at 35 km/s.
