Which best describes the way particles move to heat objects using conduction?
A
Objects generate electromagnetic waves are carried away from the object emitting them.

B
Fast-moving particles collide with slower moving particles transferring their heat energy.

C
Fast moving particles in warm objects collide with electromagnetic waves.

D
Particles expand with thermal energy, hot air rises and pushes cooler air down through circulation.

An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10

What is a possible result of higher air temperature caused by global warming

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
