Answer:

Maximum torque on the wire is 1.34\times 10^{-4}\ N-m

Explanation:

It is given that,

Diameter of the wire, d = 11.1 cm = 0.111 m

Radius of wire, r = 0.0555 m

Magnetic field, B=2.79\ mT=0.00279\ T

Current, I = 5 A

We need to find the maximum torque on the wire. Torque is given by :

\tau=IAB\ sin\theta

Torque is maximum when, \theta=90

\tau=IAB

\tau=5\times \pi \times (0.0555)^2\times 0.00279

\tau=0.000134\ N-m

or

\tau=1.34\times 10^{-4}\ N-m

So, the maximum toque on the wire is 1.34\times 10^{-4}\ N-m. Hence, this is the required solution.

Two sound waves, from two different sources with the same frequency of 420 Hz travel in the same direction at 336 m/s. The sourc
Tresset [83]

Answer:

Pi(3.14) radians or 180º degrees

Explanation:

First of all, we need to obtain the wavelength of a wave traveling to the speed of sound and 420 Hz of frequency.

The formula is:

l=wavevelocity/frequency

where l = wavelength in meters

With current values:

l = 336 [m/s]/420[1/s] = 0.8 meters

Since a complete cycle (360º or 2pi radians) needs 0.8 meters to complete, 0.4 meters or 40 cm is just half of it, making a 180º degree phase or 3.14 radians.
