Physics Question a) If an object has a mass of 250. kgs and a velocity of 3.50 m/s what is the objects kinetic energy?

b) If the object described above started from rest, what work was done on the object to obtain that final kinetic energy?

c) What is the units for the final answers of the two previous questions.

25pts the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

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.
