A 15-g 10-cm-long wire is suspended horizontally between the poles of a horseshoe magnet. The magnetic field is horizontal between the poles of the magnet where the wire is suspended. When the 0.50-A current in the wire is turned on, the wire jumps up and out of the magnet. Draw the situation, carefully indicating the direction of the current and the field. What is the minimum magnetic field created by the horseshoe magnet?

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.

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.
