Answer:
V = I(R+r)
Explanation:
According to ohms law, the current (I) passing through a metallic conductor at constant temperature is directly proportional to the potential difference (V) across its end.
Mathematically, V= IR where V is the potential difference
I is the current
R is resistance
Given emf (E) = IRt... (1)
where E is the emf
Rt is the total equivalent resistance
The external resistance Rv is connected in series with the internal resistance 'r' to give total equivalent resistance Rt = (R+r)
Substituting in equation 1
E = I(R+r)
The equivalent potential difference V = I(R+r)
Light wave gets to you first
Light travels faster than sound and is around 300000000 m/s which is faster than sound waves. And by experience, when you are looking out the window, you can see a quick flash of light (lightning), light moves very fast
The distance traveled by the egg after 2 seconds is 19.6 m.
The given parameters:
- <em>Height of the window, h = 40 m</em>
The distance traveled by the egg after 2 seconds is calculated as follows;
where;
- <em />
<em> is the initial vertical velocity of the egg = 0</em> - <em>g </em><em>is acceleration due to gravity = 9.8 m/s²</em>
- <em>t </em><em>is the time of motion, = 2 s</em>
Thus, the distance traveled by the egg after 2 seconds is 19.6 m.

The Answer should most likely be A
Explanation:
you see B and C are pretty much the same but A has more weight and more wheels (sorry been a while sense I did this so I am calling the wheel and axel points what they look like to me) with having more wheels and axels and more weight it should have a higher force advantage.
