Many fish maintain buoyancy with a gas-filled swim bladder. The pressure inside the swim bladder is the same as the outside water pressure, so when a fish descends to a greater depth, the gas compresses. Adding gas to restore the original volume requires energy. A fish at a depth where the absolute pressure is 3.0 atm has a swim bladder with the desired volume of 5.0×10−4m3. The fish now descends to a depth where the absolute pressure is 5.0 atm.

a) The gas in the swim bladder is always the same temperature as the fish's body. What is the volume of the swim bladder at the greater depth?

b) The fish remains at the greater depth, slowly adding gas to the swim bladder to return it to its desired volume. How much work is required?

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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.
