The variable represented by that symbol is: d. Net force.
Answer:
They are automated to turn off when you shut the door but if you leave it open barely enough or climb into the fridge yourself you can see that it turns off.
Explanation:
Answer:
I = 1.05x10⁻³ A
Explanation:
By definition, an electric current is the rate of charge flow at a given time:
Where:
q: is the electrons charge = 1.602x10⁻¹⁹ C
t: is the time
In a circular motion, the time is given by:
Where:
ω: is the angular speed = v/r
v: is the speed = 2.19x10⁶ m/s
r: is the radius = 5.29x10⁻¹¹ m
Now, the effective current is:
Therefore, the effective current associated with this orbiting electron is 1.05x10⁻³ A.

Five ways to decrease resistance are:
1) Increase "Current"
2) Decrease "Potential difference"
3) Decrease "length" of conductor
4) Increase "Area of cross-section" of conductor
5) Switch to material of low "Resistivity"
Hope this helps!
