Calculate the speed of an 8.0 × 104 kg airliner with a kinetic energy of 1.1 × 109 j.

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

Explain why you think this diagram shows what happened to the carbon in the biodome.

(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.
