Imagine you are sitting on a surfboard in the ocean, waiting to catch a big wave. when the ocean is still, you are sitting at a point that would be the midpoint (the undisturbed position) of any waves that come your way. you look out to see and see a set of waves coming your way. what you see is actually a pattern of troughs followed be crests of the waves moving toward you and the shore. the distance between the crests is 5 meters. a crest passes you every 20 seconds.

answer these questions:

a. what is the wavelength?

b. what is the frequency?

c. what is the wave velocity?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
