Question Suppose we measure the terminal voltage of a rechargeable NiCad battery and find it to be 1.28 V when measured by a voltmeter. (Remember: voltmeters have very high resistance.) We now connect a 8.0-ohm resistor across the terminals, and find that the terminal voltage has now changed, to 1.16 V. Find the internal resistance of the battery. .... Read More

Question Metric System Problem: 1.2.6 The diameter of an aluminum atom is about 0.24 nm, and the nuclear diameter is about 7.2 fm (femtometer = 10?15 meter). (a) If the atom's diameter were expanded to the length of an American football field (91.44 m) and the nuclear diameter expanded proportionally, what would be the nuclear diameter in meters? (b) Is the saying that "the atom is mostly empty space" confirmed by these figures? (a) m (b) Yes No Problem: 1.8.2 Freefall acceleration g .... Read More

Question QUESTION 1 A small 12.00 g plastic ball is suspended by a string in a uniform, horizontal electric field. If the ball is in equilibrium when the string makes a 30 angle with the vertical, what is the net charge on the ball? Q = C QUESTION 2 Two charges q1 and q2 have a total charge of 10C. When they are separated by 3 m, the force exerted by one charge on the other has a magnitude of 8 mN. Find q1 and q2 if (a) both are positive so that they repel each .... Read More

Question An asymmetrical quantum well is shown at right. One barrier of the well is infinitely high and the other is finite with a energy of 0.75 eV.a. Write down the general form of the electron wave functions in each of the 3 regions.b. Use the boundary conditions to come up with a pair of equations that can be then turned into a single characteristic equation for the energy levels in the well.c. Use the equation from (b) to calculate the energies for the first two bound states in the .... Read More

Question 1. A tank has a volume of 8000 gallons and is 50% full. If the tank contains water, which has a density of 8.33 lbs/gallon, how many lbs. of water are in the tank? 2. What is the volume of a tank that is 8 ft. in diameter and 15 ft. high? 3. How would you calculate the volume of a cylindrical tank that is on its side (called a horizontal tank)? Calculate the volume if that tank that is 10 ft. in diameter and 18 ft. long. .... Read More
