2. A small disk of mass 2 kg is constrained to move in a circular path by a light rod of length 3. The linear velocity of the disk is 3 m/s. A piece of putty with a mass of 0.1 kg is dropped onto the disk. If the radius of the circular path remains constant, what is the linear velocity of the disk-putty system

When the velocity of an object is doubled, by what factor is its momentum changed? by what factor is its kinetic energy changed? a) the momentum is zero. b) the momentum is not zero. c) difficult to say.

Select the word from the list that best fits the definition classification of most stars on the h-r diagram

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.
