Express the two forces in cartesian vector form when f1 = 250 n and f2 = 525 n. express the resultant vector as a cartesian vector. determine the magnitude and coordinate direction angles of the resultant. force f1 is rotated 45 degrees from the y axis in the x-y plane and 60 degrees up in the z direction. also, determine the coordinate direction angles of f1.

Avoltage source vs = 10 v is in series with a resistor of 10 kohm. if the source transformation theorem is applied, what will the value of the current source be in ma ?

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)
