A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 3.00 s for the boat to travel from its highest point to its lowest, a total distance of 0.630 m . The fisherman sees that the wave crests are spaced...

In addition to producing images, ultrasound can be used to heat tissues of the body for therapeutic purposes. An emitter is placed against the surface of the skin; the amplitude of the ultrasound wave at this point is quite large. When a sound wave hits the boundary between soft tissue and bone, most of the energy is reflected. The boundary...
point charges
A point charge q1 = -3.00 nC is at the point x = 0.600 m, y = 0.800 m, and a second point charge q2 = 6.00 nC is at the point x = 0.600 m, y = 0. Calculate themagnitude and direction (counterclockwise from the x-axis is positive) of the net electric field at the origin due to these...
