Answer:
<em>The equivalent resistance of the combination is R/100</em>
Explanation:
<u>Electric Resistance</u>
The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.
Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:
If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:
This sum is repeated 10 times. Operating each term:
All the terms have the same denominator, thus:
Taking the reciprocals:
The equivalent resistance of the combination is R/100
A or c I’m pretty sure it’s c though hope it helps:)

<span>jogs
north for exactly 5.0 min at an average speed of 8.0 km/h.
Convert velocity from km/h to km/min
V = 8.0 km/h * 1h/60min = 2/15 km/min
Distance = V*t = [2/15 km/min]*5min = 2/3 km
He continues
north at a speed of 12.0 km/h for the next 30.0 min.
Again convert km/h to km/min
V = 12.0 km/h * 1h/60min = 1/5 km/min
D = V*t = [1/5 km/min]*30min = 6 km
He then turns
around and jogs south at a speed of 15.0 km/h for 15.0 min.
Position before turning around
X = 2/3 km + 6 km = 20/3 km North
D = V*t = 15.0 km/h *(1/4 h) = 15/4 km
New position: 20/3 km North - 15/4 km South = 35/12 km North
Then he jogs
south for another 20.0 min at 8.0 km/h.
D = V*t = 8.0km/h * [1/3 h] = 8/3 km
New position 35/12 km North - 8/3 km South = 3/12 = 1/4 km North
Total distance jooged = 20/3 km + 15/4 + 8/3 km = 157/12 km = 13.08 km ≈ 13.1 km
He walks the rest of the way
home
He will have to walk 1/4 km = 0.25 km to get home after he finishes jogging
