The correct answer is letter C. Volume is decreasing. For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume<span> are </span>inversely proportional<span>. </span>
If the ground is flat, and both bullets are released at the same time from the same height, then they both hit the ground at the same time.
The horizontal motion of the one from the gun has no effect on its vertical motion.
P.E= Mass x gravity x height (standard gravity = 10m/s approaximately)
= 200x10x10= 20000j (D)
The ozone layer seem to have the greatest affect on the amount of radiation received from the sun.
