Agenerator is constructed by rotating a coil of n turns in a magnetic field b at a frequency f. the internal resistance of the coil is r and the cross sectional area of the coil is a.
true or false
the maximum induced emf occurs when the coil is rotated about an axis perpendicular to area a.
the average induced emf doubles if the magnetic field b is doubled.
the average induced emf doubles if the resistance r is doubled.
the average induced emf doubles if the frequency f is doubled.
the average induced emf doubles if the area a is doubled.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
