Answer:
r = 102.43 m
Explanation:
Newton's second law for this case is
F = ma
Where the acceleration is centripetal
a = v² / r
r = v² / a
They indicate that the radial acceleration is 8.45 g
r = v² / 8.45 g.
r = 92.1² / 8.45 9.8
r = 102.43 m
20km every 1 hr is what 20km/hr means.
so 3hrs is 20km*3=60km.
Explanation:
First, simplify the circuit. Then calculate the parallel and consecutive resistances to find the answer.
