Now, let’s see what happens when the cannon is high above the ground. click on the wheel of the cannon, and drag it upward as far as it goes (about 21 m above the ground). set the initial velocity to 20 m/s, and fire several balls while varying the angle. for what angle is the range the greatest

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. the ice dissolves oxygen from the air, forming a denser crystalline matrix. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.
