You throw a ball vertically upward so that it leaves the ground with velocity 5.68 m/s.

(a) What is its velocity when it reaches its maximum altitude? magnitude 0 Correct: Your answer is correct. m/s direction Incorrect: Your answer is incorrect.

(b) What is its acceleration at this point? magnitude -9.8 Incorrect: Your answer is incorrect. The response you submitted has the wrong sign. m/s2 direction Incorrect: Your answer is incorrect.

(c) What is the velocity with which it returns to ground level? magnitude -5.68 Incorrect: Your answer is incorrect. The response you submitted has the wrong sign. m/s direction Correct: Your answer is correct.

(d) What is its acceleration at this point? magnitude 9.8 Correct: Your answer is correct. m/s2 direction Correct: Your answer is correct.

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?
