The spring constant for a given spring is known as 100 ± 1.3 newtons per meter. When this spring is compressed by a force, the compression in the spring is measured as 0.25 ± 0.02 meter. If you calculate the potential energy stored in the compressed spring in joules, what will be the uncertainty of your answer?

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
