The ceiling of your lecture hall is probably covered with acoustic tile, which has small holes separated by about 6.9 mm. using light with a wavelength of 579 nm, how far could you be from this tile and still resolve these holes? the diameter of your eye is about 5 mm.

( )m

could you resolve these holes better with red light or with violet light? (you have only 1 try.)

1. violet.

2. red

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
