A sinusoidal wave of frequency f is traveling along a stretched string. The string is brought to rest, and a second traveling wave of frequency 2f is established on the string. (i) What is the wave speed of the second wave? a. twice that of the first wave b. half that of the first wave c. the same as that of the first wave d. impossible to determine (ii) describe the wavelength of the second wave. a. twice that of the first wave b. half that of the first wave c. the same as that of the first wave d. impossible to determine (iii) describe the amplitude of the second wave. a. twice that of the first wave b. half that of the first wave c. the same as that of the first wave d. impossible to determine

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
