The answer is definitely letter C. They are both located in the nucleus. Their summation define the mass of one (1) atomic mass unit of a particular element. For example, for carbon atom it has 6 protons and 6 neutrons. Therefore the atomic mass of carbon is 12.
The car's average speed during that time is (23.7/2) = 11.85 m/s .
Distance = (11.85 m/s) x (6.5 sec) = 77.025 meters .
The net force is 0 N.
To find the total net force, all you need to do is add the forces.
So 100 + -100 = 0
Most of these questions are trick questions, but if you know Newton's laws of forces, then you should know that all forces should cancel out with each other.
Hope this helps!!!
Answer:
<em><u>0</u></em><em><u>.</u></em><em><u>9</u></em><em><u>1</u></em>
Explanation:
as equivalence resistance can be found out using the
1/Req = 1/r1 +1/r2 +1/r3......
now, 1/req= 1/2+1/3+1/4
=6/12+4/12+3/12
=13/12
i.e, req =12/13 =0.91

Answer:
It would take 16.7 s for the work to be done by the engine.
Explanation:
From the question, given: Power = 390.3 kW
Work to be done = 6.5 x 
J
But, power and work done with respect to time, has a relationship of:
Power = 
So that,
time = 
Thus,
time = 
= 16.6539
time = 16.7 s
Time required is 16.7 seconds.
Thus, it would take 16.7 s for the work to be done by the engine.
