natural motion is the motion that requires no force
(a) the three resistors are in parallel, so the equivalent resistance R is given by
1/R= 1/5 + 1/10 +1/15
1/R= 11/30
R=2.7ohm
(b) Voltage in the circuit= 120 V
(c) for current, we use ohm's law
V= i R
120= i (2.7)
i=44 A
Answer:
a ball hanging from a tall pole
Explanation:
work is force times a distance in the direction of the force. The ball just hanging there has no motion, so is associated with no work. Work was probably done in the hanging process, but none after.
