The correct diagram is C.
In fact, the magnetic force works as the electrostatic force: like poles repel each other, while opposite poles attract each other. In this example, we have two magnets one next to each other, and we see that the north pole of one magnet is close to the south pole of the other: therefore, the two poles attract each other, so the two magnets will move closer, as in diagram C.
F= 6m.m2/r^2
F= (6.673x10^-11)(70)(3.32x10^23)/(2.44x10^6)^2
ANS: F= 260 N=2.60x10^2 N
It’s literally in your reading go re reas
<u>The correct answer is 580.
</u>The upward force the right tension cord exerts on the traffic light is equal to about 114.35 N. Because the stoplight is being help upright the natural force (upward force) provided by both tension cords must be equal to the gravitational (downward) force of the traffic light which is 331.
If 114 is the upward force on the right side then 216 N must be the force provided by the left side.
You then have a right triangle with the length opposite theta = about 216 and theta = 22. So sin(22)* X = 216, where X is the length of the hypotenuse, or the force found in the left cord.
with sig figs added to the mix the answer is 580 N
I believe the answer is true to the E dgenuity physics course
