What are the options u can't say that and expect me to know wat u talkin bout
Answer:
0.66
Explanation:
By using the formula
u = v^2 / r g
Where u is coefficent of friction
u = 23.5 × 23.5 / (85 × 9.8)
u = 0.66
You draw a straight line from the start point to the end point. It doesn't matter what route was actually followed for the trip.
25 volts
Explanation:
Use Ohm's law to find the potential drop:
V = IR
= (0.5 A)(50 ohms)
= 25 volts
