What is the hall effect?

At t = 0.0 s, a runner is moving forward (in the positive direction along the x-axis) at a speed of 7.0 m/s. For 2.0 s the runner accelerates to his left at 0.50 m/s2 and backward at 1.0 m/s2 . What is the runner's position at t = 2.

Clearly distinguish between mass, weight, and volume.

Why do we need gravity?

A gyre is a set of currents that form: a. a line b. a loop c. weather d. climate zones

As a train accelerates away from a station, it reaches a speed of 4.9 m/s in 5.1 s. If the train's acceleration remains constant, what is its speed after an additional 7.0s has elapsed?

If you combine 430.0 ml of water at 25.00 °c and 140.0 ml of water at 95.00 °c, what is the final temperature of the mixture? use 1.00 g/ml as the density of water. s

While working out, a man performed 200 j of work in 3 seconds. What was his power?
