Answer:
0.231 N
Explanation:
To get from rest to angular speed of 6.37 rad/s within 9.87s, the angular acceleration of the rod must be

If the rod is rotating about a perpendicular axis at one of its end, then it's momentum inertia must be:

According to Newton 2nd law, the torque required to exert on this rod to achieve such angular acceleration is

So the force acting on the other end to generate this torque mush be:

<span>Both electric and magnetic fields exert body forces, meaning they act from a distance. The like charges and poles in both repel; positive charge repels positive and the north pole repels the north pole. For both, the opposite poles/charges attract. Finally, only magnetic fields have poles, and there are two poles, namely the south and north, so they are dipolar.
The diagram that represents all of this information correctly is the third.</span>
I guess the same effect as increased temperarure - ice melting, weather change, ecosystem change, crop agrculture, etc
Answer:
Explanation:
vi = 200/5 = 40 m/s
a = (vf - vi)/t = (60 - 40)/20 = 1 m/s²
F = ma = 2000(1) = 2000 N
1) C
2) 2[A]
3) 2[A]
4) a less bright (?)
b 1 [A]
c 1 [A]
5) brighter (?)
6)
a 0.8 (if it is the one on the right of 6)
b 0.4 [A]
c 0.4 [A]
d depends on where you place it.
7)
a place it next to X, right or left
b place it just after the source
(?) = not sure
