The sunlight I = 1.4 kW/m2. What is its pressure on a beach towel if the light is totally reflected by it?

An inductor (inductance L) and a capacitor (capacitance C) are connected as shown. If the values of both L and C are doubled, what happens to the time required for the capacitor charge to oscillate through a complete cycle (this time is the period)?  

Suppose the moving rod in Figure is 0.10 m long, the v = 2.5 m/s, the total R = 30 W, and B = 0.60 T. Find the emf and magnetic force direction on the rod ab.  

Changing electric flux is equivalent to current in terms of generating magnetic field. And this changing electric flux is called displacement current. Who discovered this phenomenon and it is represented in which law?

(see figure below) A circular loop of copper wire is in a region of spatially uniform magnetic field. The magnetic field is directed into the plane of the figure. If the magnetic field magnitude is increasing, what is the direction of current in the loop?  

The figure shows a wire coil being squeezed in a uniform magnetic field. While the coil is being squeezed and its surface area becomes smaller, what is the direction of induced emf in the coil?
