1. If a wave traveling through air decreases its wavelength by half, describe what happens to the wave speed and frequency.
2. A transverse wave is traveling down a rope with mass, m = 10 kg, and length, L = 50 m. If the rope is under a tension force of 2000 N, calculate the wave speed of the transverse wave. Show your work.
3. If a slinky has a mass of 0.5 kg and 100 loops, calculate the mass density (m/L) of a slinky that is stretched 5 m, but only 80 loops are stretched. Show your work.
4. Cite one example when you have experienced the Doppler effect and explain how it represented this scientific principle.
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
A resistor is in the shape of a cube, with each side of resistance R . Find the equivalent resistance between any two of its adjacent corners.
