1. A battery with an internal resistance of 0.50 ohms has a current of 0.78A through it when it is connected in a circuit whose external resistance is 1.50 ohms. In this circuit, what is the potential difference between the terminals of the battery?
2. Power is being transmitted through normal transmission lines from a generator to a substation. If the input voltage is doubled and the current halved, how will the power input and the useful power output change?
Now calculate the velocity of this transfer orbit at two places. You want to know the velocity of the transfer ellipse at perigee.

You throw a ball straight up in the air. The instant after leaving your hand, the balls speed is 30 meters per second. Ignoring the effects of air resistance, predict how fast the ball will be traveling 2 seconds later.
In an 8.00km race, one runner runs at a steady 11.3km/h and another runs at 14.5km/h. How far from the finish line is the slower runner when the faster runner finishes the race
A charging RC circuit controls the intermittent windshield wipers in a car. The emf is 12.0 V. What resistance should be used in the charging circuit
A sailor strikes the side of his ship just below the waterline. He hears the echo of the sound reflected from the ocean floor directly below 1.4 s later. How deep is the ocean at this point? Suppose the speed of sound in seawater is 1560 m/s(Table 12..
