B. the total kinetic energy of its particles

C. the total potential energy of its particles

D. its total temperature

When a force on an object increases how does the object's acceleration change?

The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. To see just how rapidly windows conduct heat, calculate the rate of conduction in watts through a 2.82 m2 window that is 0.

What type of rays are used to locate cavities in teeth? Radio waves, infrared rays, ultraviolet rays, microwaves, x-rays, or gamma rays

What kinds of forces hold ionic solids together? Check all that apply. Check all that apply. dispersion forces metallic bonds covalent bonds electrostatic attraction dipole-dipole forces hydrogen bonds

During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.148 kg baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 15.

What causes day and night on earth?

A yo-yo can be thought of as a solid cylinder of mass m and radius r that has a light string wrapped around its circumference (see below). One end of the string is held fixed in space.

Why is time an independent variable and position is a dependent variable in a position versus time graph

A geologist estimates that a large boulder weighs 7840 N. What should he estimate the mass of this boulder to be? A. 650 kg B. 740 kg C. 780 kg D. 800 kg

Two objects have the same momentum. Do the velocities of these objects necessarily have (a) the same directions and (b) the same magnitudes? Give your reasoning in each case.
