Calvert likes to paddle around in his canoe. one day it sprung a leak and started to fill with water. luckily, calvert was able to swim to shore, but the boat sank.
why did the boat sink?
a)the hole in the boat increased the density of the boat, so it was not able to float.
b)the weight of the water was greater than the buoyant force on the boat.
c)the boat was able to displace less water, so it was not able to float.

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

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?
