The direction of current in the conductor is (a) perpendicular to the direction of voltage supply
(b) in the opposite direction of flow of electron
(c) perpendicular to the direction of electrons
(d) parallel to the direction of electrons​

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)

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.

Is the vertical component of velocity ever zero?
