Acertain perfect gas is compressed reversibly from 1 bar, 17 °c to a pressure of 5 bar in a perfectly thermally insulated cylinder, the final temperature being 77 °c. the work done on the gas during the compression is 45 kj/kg. calculate γ, cv, r, and the molar mass of the gas.

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.

explanation:

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

no simpler subs form complex ones. synthesise = make

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
