A sinusoidally oscillating current I() with an amplitude of 9.55 A and a frequency of 775 cycles per second is carried by a long, straight wire. A rectangular loop of copper wire with dimensions b-72.2 cm by e 32.5 cm is located Q-80.2 cm from the straight wire, and is coplanar with it. Calculate the average power Pave dissipated by the loop if its resistance is 84.32. Pave = 1.08

Example 1 A star undergoes some mode of oscillation. Scientists/engineers have hypothesized that the oscillation frequency (cycles per second), o, is dependent on the density p and the radius R and the gravitational constant G which appears in Newton's law of universal gravitation. If you are not familiar with the gravitational constant, read the section on mass and weight in Chapter 4 (Dimensions/units) of the text. Therefore, w has dimensions (T), and P, R, Gare the governing parameters, with dimensions...
