Two coils are wound around the same cylindrical form. When the current in the first coil is decreasing at a rate of -0.245 A/s , the induced emf in the second coil has a magnitude of 1.70×10?3 V .

Part A

What is the mutual inductance of the pair of coils?

Part B

If the second coil has 29 turns, what is the flux through each turn when the current in the first coil equals 1.15 A ?

Part C

If the current in the second coil increases at a rate of 0.365 A/s , what is the magnitude of the induced emf in the first coil?

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.

Which best describes the difference between internal and thermal energy?
