Answer:
I'd go for 'Marie drives a car'
Explanation:
Static electricity will possible form in all the scenarios, but is more likely to form when you're driving a car. This is due to the friction between the body of the car and the particles in the air around the body of the car. This is why chains are sometimes attached to fuel tankers when transporting them. The chain is made to touch the ground so that any charge built up can be safely conducted to the earth, reducing the chances of a fire outbreak due to charges igniting the fuel.
Ok, I think this is right but I am not sure:
Q = ϵ
0AE
A= π π
r^2
=(8.85x10^-12 C^2/Nm^2)
( π π (0.02m)^2)
(3x10^6 N/C) =3.3x10^-8 C = 33nC N = Q/e = (3.3x10^-8 C)/(1.60x10^-19 C/electron) = 2.1x10^11 electrons
Answer:
60 Ohms
Explanation:
Ohms law states that the voltage in the circuit is directly proportional to the current through the circuit components and expressed as
V=IR
Where V is the voltage, I is current and R is resistance
Making R the subject of the formula then
Substituting 3.0V for V and 0.05 A for I then
Therefore, resistance is 60.0 Ohms
