Canas O 172x10s O None of the above Question 17 1 pts You are using an antenna consisting of a single loop of wire of radius 15.0 cm to detect electromagnetic waves for which E.. 0.200 Vm f the wave frequency is 600 kHz, the rms value of the emf induced in the loop is approximately O 32.1 M O 843 O 66.7M O 178v O 643w Question 18 1 pts Charge is flowing onto one plate of a parallel-plate capacitor and off the other plate at a rate of 2.50 A. The rate at which the electric fheld between the plates is changing is approximately O545-30N-m2nc O 113-30lNmC-s O 282 50 N C- O 124-50NAC O 174 10 N AC Question 19 1 pts

Answer 1

Sol 471) Radius of the loop, 8 15cm Rmg value of electric field is, Erms = 0.2 von ... Inequency, fa 600 KHZ. so Rms value of Emf induced, Esms [20 kms fr27 sonere cis I speed of or, Erns 24 x 0.2 x 600 xlox (0.15² 38108 of Esms 177.65 MV ~ 178 mv e light) (18) Corrent flowing from one a plate to other is: iz 25 A so note of change in electric field B/w the plates is (dt) (eo) (8.854x1012). (b) – 2.82% 10" N.m/
