Aloop of wire of radius a = 35 mm has an electrical resistance r = 0.036 ω . the loop is initially inside a uniform magnetic field of magnitude b0 = 1.5 t parallel to the loop's axis. the magnetic field is then reduced slowly at a constant rate, which induces a current i = 0.20 a in the loop. how long does it take for the magnitude of the uniform magnetic field to drop from 1.5 t to zero?

Which composition of water moves to begin a deepwater current?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.

If you drive 12 miles north and 35 miles east, what is the direct distance between you and your starting point?
