4. Identify the part or item associated with the internal-combustion engine that the statement is
describing. Choose from the following parts: cylinder, engine block, piston, cylinder head,
combustion chamber, intake valve, exhaust valve, spark plug, stroke, and crankshaft.
a. The metal cover that seals the top of the cylinder
b. The valve that allows burned gases (waste products) to vent out of the cylinder
c. A solid metal into which the cylinder is drilled
d. The total distance that the piston moves from the top of the cylinder to the bottom
e. A can-shaped component that can move smoothly up and down inside the cylinder
f. The valve that allows the air-and-fuel mixture to be delivered to the cylinder
g. A hollow metal tube drilled into the solid metal engine block
h. The open area located above the piston, positioned at the very top of the cylinder (This is
where the air and gasoline mix and burn to produce power.)
i. Piece connected to the piston by a connecting rod (With the rod, this part converts the up-and-
down motion of the piston to rotary motion, which makes the car move forward.
j. Part screwed into a hole in the cylinder head and used to make sparks that will ignite the air-
and-fuel mixture in the cylinder and cause it to burn.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge รขโฌโq to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge รขโฌโ to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70ยฐc. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
