A16.0 kg canoe moving to the left at 12.5 m/s makes an elastic head-on collision with a 14.0 kg raft moving to the right at 16.0 m/s. after the colli-
sion, the raft moves to the left at 14.4 m/s. what is the final velocity of the canoe? disregard any effects of the water.
o 14.1 m/s to the right
o 13.9 m/s to the right
14.1 ms/to the left
13.9 m/s to the left

Blank liquids and gases exert a buoyant force on objects placed in them

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
