You hurry to your physics class after a yummy meal in the cafeteria. In your arms you carry books that include your highly valued Composition book. All together the food and the binder weigh 22 N. How much work is done on the books when you walk 80 m along the hall, go up stairs 12 m high, and then turn right for an additional 15 m to class?​

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Arrange the images in order to show how lake-effect snow occurs.

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?
