Asquare wire, 20 cm on the side, moves at constant speed parallel to the xy-plane into a region where there is a uniform magnetic field = (0.1 t) .the induced electric current in the coil is 10 ma and its resistance is 10ω. what is the speed of the wire?

The speed of the wire is 5 m/s.

Explanation:

Given that,

Length = 20 cm

Magnetic field = 0.1 T

Current = 10 mA

Resistance

We need to calculate the  speed of the wire

Using formula of emf

Using formula of current

Put the value of into the formula of current

Hence, The speed of the wire is 5 m/s.

d.7.5cm is your answer

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
