When a particular wave is vibrating with a frequency of 4.00 hz, a transverse wave of wavelength 60 cm is produced. determine the speed of waves along the wire.

Speed = 2.4 m/s

Explanation:

As given in question,

Frequency of the wave = 4 Hz

The wavelength of the wave = 60 cm

As we know,

   1 cm = 0.01 m

=>60 cm = 0.6 m

So, the wavelength of the wave = 0.6 m

speed of wave = wavelength x frequency

                           = 0.6 m x 4 Hz

                           = 2.4 m/s

Hence, the velocity of wave vibrating with 4 Hz frequency and wavelength of 60 cm is 2.4 m/s.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
