The speed of sound v in a medium depends on its wavelength 2, the young
moduluse, and the density p, of the medium. use the method of dimensional
analysis to derive a formula for the speed of sound in a medium. (unit for
young modulus e: kgm-15-2)

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
