Mr. Quark says that it is cheaper to buy regular 1.5 Volt D-size batteries to supply electricity for a house. According to him, you can buy 80 of them (80x1.5v-120 volts), turn off your AC source from your local electric power company, and replace it with your D-size batteries. Do you agree or disagree with Mr. Quark? Explain!

1. You've recently read about a chemical laser that generates a 20-cm-diameter, 25 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20-cm-diameter, 100 kg, perfectly absorbing block. What speed would such a block have if pushed horizontally 100 m along a frictionless track by such a laser?
4. A circular capacitor of radius R holds a conductive current I. as it begins charging. As the current charges the capacitor, the electric field between the plates begin to increase in strength of E(t) = at³ +c in Newtons per Coulomb. (a) State the expression for Maxwell-Ampere's law. What is the major dif- ference between the Maxwell-Ampere law and Ampere's Law? Show how we arrive to this solution.

2. An electron starts from rest near the negative vertical plate of a set of parallel plates and accelerates towards the positive plate through 150 V. After crossing this distance the electron passes through a hole. The electron then moves through a horizontal set of parallel plates where the top plate is negative. These horizontal plates are separated by 2.0 cm and have a potential difference of 240 V. The electron passes through these plates undeflected due to a magnetic field perpendicular to the page. The electron then passes out of the plates where it is acted upon by the same uniform magnetic field. Find the magnitude and direction of the uniform magnetic field and the radius of the circular path of the electron. Draw the complete path of the electron. Electron starts here Magnetic and electric field here Only a magnetic field here! 150 V Path of electron

Figure 8 shows a coaxial cable (two nested cylinders) of length l, inner radius a and outer radius b. Note that l >> a and l >> b. The inner cylinder is charged to +Q and the outer cylinder is charged to −Q. The cable carries a current I, which flows clockwise. Use Ampere’s Law to calculate themagnetic field B⃗ at r<a, a<r<b, and r>b.
