Which of the following statements is FALSE about the law of conservation of momentum? *
1 point
Momentum is always conserved in the absence of outside influences.
When two cars collide and become stuck to each other, the car that originally had the greatest momentum will determine the direction of the cars.
When two cars bounce off each other after a collision, the momentum is lost into the atmosphere.
When two cars bounce off each other after a collision, the momentum is dispersed between the cars and the outside system thus conserving momentum.

Which statement best describes copper? a. it has a low resistance and prevents charges from moving freely. b it has a high resistance and allows charges to move freely. c. it has a high resistance and prevents charges from moving freely. d. it has a low resistance and allows charges to move freely

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

(a) if the pressure in gas is doubled while its volume is held constant, by what factor do (i) vrms and (ii) change? (b) is it possible to boil water at room temperature (20oc) without heating it? explain.
