The magnetic flux through a 50-cm-long solenoid that has 500 turns of radius 3.0 cm is 4.0 × 10–2 Wb. Calculate the current through the solenoid.

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
