Answer:
140 W
Step-by-step explanation:
Power is measured in joules per second, or watts. A joule is a measure of energy equal to 1 newton-meter. These unit relationships tell you how to combine the numbers:
power = (35 N)(20 m)/(5 s) = (35·20/5) N·m/s = 140 J/s = 140 W
between 7 and 8
Yes, SSS
PR are already a given side. PS and PQ are also given sides. Lastly, RS and RQ are given sides.
