A sample of compressed methane has a volume of 750 mL at a pressure of 400 kPa. To what pressure would the methane have to be compressed in order to have a volume of 250 mL?

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

i wish i could but this one is weird give me abc and i can solve it.
