An AC power supply produces a maximum voltage ΔVmax = 88 V. This power supply is connected to a resistor R = 27.0 Ω, and the current and resistor voltage are measured with an ideal AC ammeter and voltmeter as shown in the figure below. An ideal ammeter has zero resistance, and an ideal voltmeter has infinite resistance.

(a) What is the reading on the ammeter?
A

(b) What is the reading on the voltmeter?
V

A damaged car battery with an emf of 11.4 V and an internal resistance of 0.01 ohms is connected to a load of 2.0 ohms. To help the battery, a second battery with an emf of 12.6 V and an internal resistance of 0.01 ohms is connected by jumper cables to the terminals of the first battery.

1. Draw a diagram for the circuit.
2. Find the current in each part of the circuit.
3. Find the power delivered by the second battery.

Mickey Mouse and Minnie Mouse compete on a skating rink. Mickey has the mass m = 30kg, and skates to the east with the directional velocity v = 5m / s. Minnie has a mass of m = 20 kg and is firing straight into Micky's lap. In the collision, they embrace and travel both to the east, at a velocity of v = 1m / s. What was the speed of the Minnie Mouses direction for the collision?

The joint probability distribution of random variables, X and Y, is shown in the following table: X 2 4 6 Y 1 0.10 0.20 0.08 2 0.06 0.12 0.16 3 0.15 0.04 0.09

(a) Calculate P ( X=4 | Y=1)

(b) Calculate V (Y | X=2) .

(c) Calculate V (3Y-X ) .

Consider the cell described below at 267 K:

Sn | Sn2+ (0.999 M) || Pb2+ (0.975 M) | Pb

Given EoPb2+→Pb = -0.131 V, EoSn2+→Sn = -0.143 V. Calculate the cell potential after the reaction has operated long enough for the Sn2+ to have changed by 0.397 mol/L
