A plug-in transformer supplies 9.00 V to a video game system. How many turns are in its secondary coil if its input voltage is 120 V and the primary coil has 381 turns?

(A) A plug-in transformer supplies 9.00 V to a video game system. How many turns are in its secondary coil if its input voltage is 120 V and the primary coil has 381 turns? What is its input current when its output is 1.33 A?

(B)What is the characteristic time constant of a 24.2 mH inductor that has a resistance of 4.08 Ω? If it is connected to a 12.0 V battery, what is the current after 12.5 ms?

(C)Two protons are released from rest, one from location 1 and another from location 2. When these two protons reach location 3, the first proton has a speed that is 4 times the speed of the second proton. If the electric potentials at locations 1 and 2 are 231 V and 115 V, respectively, what is the electric potential at location 3?

(D)Two microwave frequencies are authorized for use in microwave ovens: 910 and 2590 MHz. Calculate the wavelength of each.
