A cylindrical metal rod is 2.40 m long and 5.99 mm in diameter. The resistance between its two ends (at 20oC) is 1.38 * 10-3 Ω. (a) What is the material? (b) A round disk, 2.24 cm in diameter and 1.20 mm thick, is formed of the same material.

Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does that mean that the acceleration of car A is greater than that of car B? Explain.

A motorist enters a freeway at 45 km/h and accelerates uniformly to 99 km/h. From the odometer in the car, the motorist knows that she traveled 0.2 km while accelerating.

What is the Coriolis Force?

Einstein's general theory of relativity made or allowed us to make predictions about the outcome of several experiments that had not yet been carried out at the time the theory was first published.
