A drop of water has an electric charge of -1.6 x 10^-16 C. How many excess electrons does this drop of water have?! (Let the elemental charge: 1,6.10^-19)
a) 100
b) 300
c)625
d) 1000
e)1600

if you steal my POINTS you will be reported

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 = 2.6 m below the tank bottom which is a = 6.7 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). report your answer in meters to two decimal places.
