In a certain time period a coil of wire is rotated from one orientation to another with respect to a uniform 0.38-t magnetic field. the emf induced in the coil is 5.8 v. other things being equal, what would the induced emf be if the field had a magnitude of 0.55 t?

8.4 V

Explanation:

induced emf, e1 = 5.8 V

Magnetic field, B1 = 0.38 T

magnetic field, B2 = 0.55 T

induced emf, e2 = ?

As we know that the induced emf is directly proportional to the magnetic field strength.

When the other parameters remains constant then

e2 = 8.4 V

Thus, the induced emf is 8.4 V.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
