Question 1 Question 3 This question contains multiple parts. Make sure to read all the instructions and answer each part. A and B are communicating with walkie-talkies. B's walkie-talkie emits a radio wave of frequency 200 MHz uniformly in all directions with a power of about 3.3 W. A is 2.7 km away. What is the electric field amplitude of B's radio signal once it reaches A's walkie-talkie?

Make sure to read all the instructions and answer each part. Part a As shown in the figure, a ring is coaxial to a solenoid, and the solenoid is attached to a fully What is the direction of the current in the loop? charged capacitor. Suppose the solenoid has 10 turns per unit length and a radius of 10 cm. The ring has a radius of 20 cm and it has a resistance of 1 Ohm. Initially, the capacitor outputs current 10 A, but the Select the correct answer current quickly decays to zero linearly in 5 seconds. counterclockwise Image size: SN O clockwise Part b (1 points What is the distance d from the center of the loop to the wire?
