You are assigned the design of a closed, cylindrical, pressurized water tank for a future colony on mars, where the acceleration due to gravity is 3.71 meters per second per second. the pressure at the top surface of the water will be 110 kpa, and the depth of the water will be 14.3 m . the pressure of the air in the building outside the tank will be 94.0 kpa . the tank is stationary and held up from above, so that the bottom surface of the tank is in contact with the atmosphere in the building. find the net downward force on the tank's flat bottom, of area 2.15 m2 , exerted by the water and air inside the tank and the air outside the tank.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
