Aglass has circular cross sections that taper (linearly) from a radius of 4 cm at the top of the glass to a radius of 3 cm at the bottom. the glass is 18 cm high and full of orange juice. how much work is required to drink all the juice through a straw if your mouth is 5 cm above the top of the glass? use 1000 kg divided by m cubed for the density of orange juice and 9.8 m divided by s squared for the acceleration due to gravity.

In what direction does the medium move relative to the direction of the wave? explain.

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2

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?
