The water in the plumbing in a house is at a gauge pressure of 350,000 pa. what force does this cause on the top of the tank inside a water heater if the area of the top is 0.9 m2? (ignore atmospheric pressure.)

Aplane's average speed between two cities is 600 km/h. if the trip takes 2.5 hours, how far does the plane fly?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).

Which of the following is a transformer used for? alternate a voltage produce a voltage increase or decrease a voltage eliminate a voltage
