Three 20-o resistors are connected in series across a 120-V generator. Find the equivalent resistance of the circuit. a. 300
C. 200
b. 600
d. 800

600

Explanation:

Resistors that are connected in series are simply added. So three 200 ohm resistors connected in series make 200 + 200 + 200 = 600

b

Explanation:

answer: the answer is a

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
