Along, thin solenoid has 950 turns per meter and radius 3.00 cm. the current in the solenoid is increasing at a uniform rate of 63.0 a> s. what is the magnitude of the induced electric field at a point near the center of the solenoid and (a) 0.500 cm from the axis of the solenoid; (b) 1.00 cm from the axis of the solenoid?

Part a)

N/C

Explanation:

As we know that the magnetic field near the center of the solenoid is given as

Also we know by  equation of Faraday's law

EMF induced in the closed loop will be equal to rate of change in magnetic flux

so we have

so we have

Part a)

At r = 0.500 cm

we have

Part b)

At r = 1.00 cm

we have

N/C

i think the answer is a, hope this : )

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
