A straight wire has a current of 150 A flowing north. What is the magnitude and direction of the magnetic field at a point 1.0 m east of the wire?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

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.)
