The best choice would be C. Keep one end of the rope tied to the post and have all six boys tug on the other end.
Reason:
A is not correct since in the first case which is B, untying the rope from the post and have 3 boys on each end of it tug, will provide equal or a near equal amount of tension since the boys are all within the same strength, however there can be variables that will affect the tension.
That means B would be true according to A, and then for C, having all six boys pull on the other end of the rope would provide greater tension, since if 3 boys of the same strength range can't break the rope when its tied to the fence, we add the other 3 boys of the same strength.
However, if 3 boys are on each end of the rope and of the same strength then the rope will not break since there is an equal amount of net force exerted on the rope.
We know that the fence can withstand the strength of 3 boys but if we add the other 3 boys then it could provide us with a different outcome.
3B < F
3B(2) ≥ F
So, therefore, our best choice would be C since A and B is incorrect.
The particles that move in orbits of the same radius have the same momentum.
<h3>
Orbital angular momentum:</h3>
A point particle's three-dimensional angular momentum is traditionally represented by the pseudovector r p, which is the cross product of the particle's position vector r (relative to some origin) and momentum vector, which in Newtonian physics is denoted by p = mv.
L = mr
= mr²w is the particle's orbital angular momentum in units of magnitude. The part of the particle's velocity that is here perpendicular to the axis of rotation is designated as 
The right-hand rule indicates the direction of the angular momentum. In isolated systems, the angular momentum is conserved.

Answer:
Explanation:
For reduction
Execution time = (instructions * CPI)/(Clock rate)
Since CPI is increased by 18%
18/100 +1 = 1.18
Therefore
P1 CPI = CPI x 1.18
P2 CPI = CPIx 1.18
P3 CPI = CPI x 1.18
Since clockrate reduces by 30% we have it to be a 0.7
P1: (Instructions x P1CPI) / 0.7
P2: (Instructionsx P2CPI) / 0.7
P3: (Instructions x P2CPI) /0 .7
It would be electromagnet;magnetic
