Halogen lightbulbs allow their filaments to operate at a higher temperature than the filaments in standard incandescent bulbs. for comparison, the filament in a standard lightbulb operates at about 2900k, whereas the filament in a halogen bulb may operate at 3400k. which bulb has the higher peak frequency? calculate the ratio of the peak frequencies. the human eye is most sensitive to a frequency around 5.5x10^14 hz. which bulb produces a peak frequency close to this value?

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)
