It is observed to be at a distance of 50 kiloparsecs and moving at a speed of 150 kilometers/second. What is the mass contained within the radius of the orbit of the Large Magellanic Cloud and, therefore, a lower limit to the mass of our Galaxy?

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.
