newton's 2nd law says that acceleration is proportional to the unbalanced force put on an object. (f = ma) in plain english, this means:

a. if you double the force, the acceleration will double too.

b. if you double the force, the acceleration will decrease to half.

c. if you double the force, the acceleration will triple.

When barack obama was running for president, at a campaign stop he tried to bowl, something he isn't very good at. the media loved it because he threw a gutter ball while they were all watching. this is an example of:

If you let go of the notebook after lifting it, will it move? how?

An air standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes. 1-2 isentropic compression 100 kpa and 22°c to 600 kpa 2-3 v=constant heat addition to 1500 k 3-4 isentropic expansion to 100 kpa 4-1 p=constant heat rejection to initial state (a) show the cycle on p-v and t-s s (b) calculate the net work output per unit mass (409 kj/kg) (c) determine the thermal efficiency (47.9%)
