The kinetic theory is useful for a explaining how matter and energy are not always related. b testing the temperature of a gas. c determining how much heat is necessary to melt a solid. d showing the differences between states of matter.

A cyclical motion occurs because of density differences in the mantle. Heated, less dense lower regions of the fluid mantle rise, and denser, cooler regions sink due to gravity. The combined motions serve as the engine for crustal plate movement. A.

Is it possible to have negative specific heat? Explain.

What is the reason for Mary's resemblance to her mother. Mary's relatives and friends feel she had her mothers feature

What are the units for mass and volume

A child is riding a bike at a speed of 0.6m/s with a total kinetic energy of 12.4J. If the mass of the child is 30kg, what is the mass of the bike?

The kinetic energy of a moving object is equal to the work required to bring it to its speed from rest, or the work the object can do while being brought to rest.

Imagine standing on a bathroom scale and reading your weight. now lift one foot and read your weight again. does the scale read more, less or the same weight when you are standing on one foot?

The period T of a simple pendulum depends on the length L of the pendulum and the acceleration of gravity g (dimensions L/T^2). (a) Find a simple combination of L and g that has the dimensions of time.

What is an example of the theory that the best adapted organisms for an environment are the ones most likely to survive
