Answer:
weeds out the weak, sick, and old by killing them
I can't decide between A and B, but B seems more likely to me. Even though the molecules don't look like they're moving, the area of contact is slightly more compressed.
1) dc
2) ac
Because my dad said so
Answer:
(A) 12.222 ohm (B) 990 W
Explanation:
We have given the voltage of the heating element V = 110 V
The current in the heating element i = 9 A
(a) According to ohm's law V =iR
So 

(b) The power dissipated in the resistor is given by
So the power dissipated = 990 W
