Jack and jill exercise in a 25.0-m-long swimming pool. Jack swims nine lengths of the pool in 157.9 seconds (2 minutes and 37.9 seconds), while jill, the faster swimmer, covers ten lengths in the same time interval.

Maia says that both lines on this position vs time graph show acceleration. Is she correct? Why or why not?

The observation location A is located at m. The conventional current running through the wire is 7.5 amperes. In this exercise you will calculate the magnetic field at the observation location due only to segment 4 of the wire.

The wavelength of a light wave can be used to measure which of the following? A. The direction the wave is traveling B. How many photons the wave contains C. How much energy the wave has D. How high the top of the wave is

Sound 1 has an intensity of 38 W/m2. Sound 2 has an intensity level that is 2.5 dB greater than the intensity level of sound 1. What is the intensity of sound 2?

A cannonball is launched horizontally off a 20 m high castle wall with a speed of 85 m/s. How long will the cannonball be in flight before striking the ground? What is the range of the cannonball?

It is well known that bullets fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman's chest with bullets of mass m = 1.7 g at a rate of R = 165 bullets/min. The speed of each bullet is v = 380 m/s.
