Problem 68

When the Moon is in its new-moon position (directly between the Earth and the Sun), does the net force exerted on it by the Sun and the Earth point toward the Sun, or point toward the Earth? Explain. (Refer to Conceptual Questions 12 and 13 as well as Figure 1220.)

Step-by-Step Solution:
Step 1 of 3

Chapter 23: Magnetic Flux and Faraday’s Law of Induction Flux=BAcos (thet)  o Unit is Weber (Wb) o B is magnetic field o A is area  Magnetic flux if used in the calculation of the induced emf  Faraday’s Law: an emf is induced only when the magnetic flux though a loop changes with time Change∈ flux o Change∈time ) emf =−N ¿  Lenz’s law: an induced current always flows in the direction that opposes the change that caused it.  Electric field caused by the motion of a rod: o E=Bv  When a switch is added to a circuit and when the switch is closed, the current starts to increase immediately. As time goes on, the current increases more slowly and the potential difference across the inductor decrea
