Ihave an exam tomorrow and just need to know the steps and equations to find the induced current in a coil because of the solenoid. i also someone to explain how to find the direction of the current. just keep it clear and not confusing.

Which of the following is not a transverse wave? a) soundb) lightc) radiod) all of thesee) none of these

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
