An otherwise empty room contains 6 x 1026 air molecules. How many times more probable is it that they are split exactly 50-50 between front and back halves of the room than that there is a 49-51 spl
Suppose the mirror is convex. The distance between the image and the object is the same as in part (a), but the image is 0.500 the size of the object. Determine the focal length of the mirror.
Find the angular separation in the first-order spectrum of the two lines that have wavelengths equal to 579 nm and 577 nm.
It is illuminated normally by white light. Analysis of the reflected light shows that the wavelengths 360, 450, and 602 nm are the only missing wavelengths in or near the visible portion of the spec

What is the difference betweeen the angles of incidence of the two rays?
Explain why the ability to distinguish the two headlights of an oncoming car, at a given distance, is easier for the human eye at night than during daylight hours.
Why is it far less dangerous to stand in front of an intense beam of red light than in front of a very low-intensity beam of gamma rays?
A 20.0 microcoloumb charge is placed at (0,4) cm, a 4.00 microcoloumb charge is placed at (2,2), and an 8.50 microcoloumb charge is placed at (-3,-4). A)) Determine the work that was required to ass
A)) how long does it take for the proton to strike the top plate (hint: this is a projectile motion problem, find acceleration). B)) What is the horizontal range that the proton travels??
