Usain Bolt requires five seconds to step after he runs the 100 meter dash . When he wins the race he's running at 10 meters per second . What is his declaration? Please answer as soon as possible!

the answer is kevlar

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
