Technically, we have no way of knowing that without seeing Figure 16-2. So the question should be reported for incomplete content. But I'm going to take a wild stab at it anyway.
There's so much discussion of 'cylinder' and 'strokes' in the question, I have a hunch that it's talking about the guts of a 4-stroke internal combustion gasoline engine.
If I'm right, then the temperature of the material within the cylinder is greatest right after the spark ignites it. At that instant, the material burns, explodes, expands violently, and drives the piston down with its stiff shot of pressure.
This is obviously happening because of the great, sudden increase in temperature when the material ignites and explodes.
It hits the piston with pressure, which leads directly to the power stroke.
Calculate the magnitude of the linear momen- tum for each of the following cases a) a proton with mass 1.67 × 10-27 kg mov- ing with a velocity of 6 × 106 m/s. Answer in units of kg · m/s.
Wavelength spectrum of visible light for the range of 390nm to 460nm is seen as violet. So the violet colour will be seen and reflected as what the eyes will see
