Asmall, 2.00-mm-diameter circular loop with r = 1.00×10^−2 ω is at the center of a large 100-mm-diameter circular loop. both loops lie in the same plane. the current in the outer loop changes from +1.0a to −1.0a in 0.100 s . what is the induced current in the inner loop?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
