The piston diameters in fig. p1-58e are d1 = 10 cm and d2 = 4 cm. when the pressure in chamber 2 is 2000 kpa and the pressure in chamber 3 is 700 kpa, what is the pressure in chamber 1, in kpa?

908 KPa

Explanation:

See it in the pictures.

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.
