Given a car of mass 1000 kg moving along a straight flat road. the speeds up. if the final velocity of the car is 19.0 m/s and the initial velocity of the car is 4.50 m/s then what is the work done on the car?

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

Carbon 14 is a naturally occurring stable

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.
