It means you can do 550 Newton Meters of work every second. Power is the rate of doing work, I hope this helps
the first step would be gathering information , and making sure its correct
Answer:
0.94 m/s^2 downwards
Explanation:
m = 70 kg, m g = 70 x 9.8 = 686 N
R = 620 N
Let the acceleration be a, as the apparent weight decreases so the elevator is moving downwards with an acceleration a.
mg - R = ma
686 - 620 = 70 x a
a = 0.94 m/s^2
19-? Is the exact p.d across the 114-?resistor.
Current will different
But p.d will same in parallel circuit .
