Could someone PLEASE help me with these physics questions?

(7) (10 pts.) A planar electromagnetic wave is prOpagating in the +21: direction. At a certain point P and at a given instant, the electric eld of the wave is E = 0.082 V/rnj'. What is the magnetic vector (direction and magnitude) of the wave at the point P at that instant? (c = 3.0 X 108 m/s) (8) (10 pts.) Two capacitors, 01 and 02, are connected in series across a source of potential difference. With the potential source still connected, a dielectric is inserted between the plates of capacitor 01. In three or four sentences explain what happens to the charge on capacitor 02 and why? (9) (10 pts.) Consider the circuit shown in the gure. Note that two currents are shown. Calculate the EMFS 51 and 62. Show your work. 4'0 Q 1,: 4.0 FIGURE 4
