If someone wanted to manufacture a car that was identical to a volkswagen beetle, today, could they? Don't patents run out after a certain time? Or does Volkswagen still have the right to that design somehow? If you wanted to make something almost identical how close could you get? I am just curious how this works.

So far, the most accepted theory of the beginnings of the universe is the "big bang theory". if the big bang were true, then it means that everything in the universe began or started all at the same time.... then how is it that some stars are older than others, plus the supernova and black holes?

A gas is contained in a chamber such as that in Figure 15.5. Suppose the region outside the chamber is evacuated and the total mass of the block and the movable piston is 120 kg. When 2030 J of heat flows into the gas, the internal energy of the gas increases by 1745 J. What is the distance s through which the piston rises?
