A dog walks 12 meters to the east and then 16 meters back to the west. For this motion, what is the distance the dog moved?
m (answers should be rounded to the nearest tenth - Example:
0.1, 1.5, or 5.0)
What is the magnitude and direction of the displacement?
Magnitude:
m (round answer to the nearest tenth)
Direction (N, S, E, W, NE, NW, SE, SW):

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

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)

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
