We have: A= F.s
So, A = 22 x 16
A= 352J
Só A is correct answer
Time constant of a RC circuit is
Resistance x Capacitance = 120 x [330 x 10^(-6)] = 0.0396 s
Answer:
18.15 m/s
Explanation:
Radius of the loop, R = 23 m.
Weight of the rider, w= 760 N.
Mass of the rider, m = w/g = 77.5 kg
Apparent weight at the top of the loop is 350 N.

Answer:
0.5 mph in the opposite direction
Explanation:
= Mass of Cadillac = 1000 kg
= Velocity of Cadillac = 1 mph
= Mass of Volkswagen = 2000 kg
= Velocity of Volkswagen
In order to know the speed the system must have the momentum exchange
As the linear momentum of the system is conserved
The speed of the impact is given by 0.5 mph in the opposite direction
