Answer:
Explanation:
Two forces are 10 N and 30 N. Let us assume that two forces are acting in opposite directions. Net force will be :
F = 30 N - 10 N = 20 N
Now,
F = ma
⇒ a = F/m
So,
So, the acceleration of the object is .
157.5J
KE=1/2 mv^2
KE= 1/2(35kg)(3m/s)^2
KE=(17.5kg)(9m^2/s^2)
KE= 157.5J
Without magnetic domains a magnet would have its magnetism. Magnetic domains are clusters of iron atoms that line up in the same direction when magnetized. When not magnetized the iron atoms scatter.
In a magnetic field, it would require the thing that passes through it to have all their electrons paired up for it to be unaffected or repulsed. And if there is an empty orbital or an unpaired electron, it’ll be attracted. Sunlight can’t have these properties, it has no charge or mass
