1. Given three capacitors, C1 = 2.0 F, C2 =1.5 F, and C3= 3.0 F, what arrangement

of parallel and series connections with a 12-V battery will give the minimum

voltage drop across the 2.0-F capacitor? What is

the minimum voltage drop?

2. Suppose three parallel-plate capacitors,

whose plates have areas A1, A2, and A3 and

separations d1, d2, and d3, are connected in

parallel. Show, using only Eq. 242, that Eq. 243 is valid.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
