You apparently skipped some words and didn't copy them into the question. Fortunately, those words were part of the "red herring" section ... the part that only distracts you, and is completely unnecessary in order to answer the question.
The actual question here is: "What fraction of an hour is 7.2 seconds ?"
(7.2 sec) x (1 hour/3,600 sec) = 7.2 / 3600 = <em>0.002 hour </em>.
Explanation:
It is given that,
Total mass is 70 kg
The truck exerts a constant force of 20 N.
Then the net force is given by :
F = ma
a is acceleration of rider
Initial velocity of rider is 0. So, using equation of kinematics to find the final velocity as :
Since, 1 m/s = 2.23 mph
4.28 m/s = 9.57 mph
So, the speed of the rider is 4.28 m/s or 9.57 mph.
Since the anode dissolves and goes to the cathode. The object to be electroplated is kept at the cathode.
Please mark me as brainliest.
Answer:
balanced forces external forces
Explanation:
A body that is under a network of balanced external forces will experience no resultant force at all, since all the forces cancel themselves out. A body that is moving with this type of force will experience no acceleration, since there is no force acting on them. This lack of acceleration means that the body maintains a constant velocity if it is already in motion, or zero when the body is at rest.
