Find the uncertainty in a calculated electrical potential difference from the measurements of current and resistance. Electric potential difference depends on current and resistance according to this function V(I, R) = IR. Your measured current and resistance have the following values and uncertainties I = 7.9 Amps, delta I = 0.3 Amps and R = 55.7 Ohms and delta R = 0.3 Ohms. What is the uncertainty in the, delta V? Find the uncertainty in kinetic energy. Kinetic energy depends on mass and velocity according to this function E(m, v) = 1/2 m v2. Your measured mass and velocity have the following uncertainties delta m = 0.06 kg and delta v = 1.54 m/s. What is is the uncertainty in energy, delta E, if the measured mass, m = 2.27 kg and the measured velocity, v = 8.58 m/s?

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)
