When a mass m hangs from a vertical wire of length l, waves travel on this wire with a speed v. if you could explain how you got the answers and the logic that would be awesome and i'll award you the points! you! a. what will be the speed of these waves if we triple m without stretching the wire? b. what will be the speed of these waves if we replace the wire with an identical one, except twice as long? c. what will be the speed of these waves if we replace the wire with one of the same length, but two times as heavyd. what will be the speed of these waves if we stretch the wire to thrice its original lengthe. what will be the speed of these waves (in terms of v) if we increase m by a factor of 18.0, which stretches the wire to double its origina length?

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? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
