How many cm/s2 of acceleration should correspond to 1 unit of ramp slope if: •a graph of number of paper clips needed to maintain equilibrium vs. ramp slope has slope 38 clips / unit of ramp slope, and •a graph of the acceleration of a cart vs. the number of paper clips attached by a string and suspended over a pulley has slope ( 27 cm/s2) / clip? If we require 36 clips to match the mass of the cart, then if we could apply this force to the cart without the extra mass of all those clips, what would be the acceleration of the cart?
We have a container of a hot ideal monatomic gas. The volume of the container is 25 liters. The temperature of the gas is 398 C, Find the change of internal energy of the gas
