Water is supplied to an office building 31.5 m high through a pipe at ground level.
(a) find the minimum pressure in the supply pipe so that water can reach the top floor of the building.

(b) suppose the pressure in the supply pipe is designed so that water can flow out through a much smaller pipe on the top floor at a speed of 4.65 m/s. find the pressure in the larger pipe on the ground floor.

the first correct answer will get the brainliest

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.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
