Pretty sure it is clockwise if I am not mistaken
Properties that define the light is a wave are
1. Speed : speed of light is 300,000 Km /s, It is most fundamenta property of light to define light is a wave
2. Reflection: Light particles or photons reflect off the particles or masses are continue to travel at the same speed.

Electrical kettle:
P = 2 KW = 2000 W
U = 200 V
⇒ I = P/U = 2000 / 200 = 10 A
We apply the Law of Ohm:
R = U / I = 200V / 10A = <u>20 Ω</u>
=======
Electrical heater:
P = 1 KW = 1000 W
U = 240 V
⇒ I = P/U = 1000 / 240 = 4,16 A
We apply the Law of Ohm:
R = U / I = 240V / 4,16A = <u>57,69 Ω</u>
<u>Answer:</u>
The device with the highest resistance is <u>the electric heater.</u>

It look like a storm is forming out into the ocean and building pressure and maybe become a hurricane.
I hope this helps :)!!!
I believe the answer would be A. because a magnet has both a south and a north pole, and electrical charges are formed by positive and negative forces. Hope I helped!
