Kinetic energy- energy of movementa. thermal energy - heat, cells rarely use to do work, instead use in homeostasisb. radiant energy - energy of photons, converted to thermal energy and potential energy during photosynthesisc. electric energy - energy of moving charged particles

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
