Metals, especially iron, have this form of electron cloud around it. When it's placed in a magnetic field these electrons line up
Answer:
Smaller refractive power
Explanation:
The refractive power of an eye is the extent to which it can converge or diverge the light rays.
Near point is the the closest point for an eye such that when an object is placed at that point the image it forms is sharp and clearly visible to the eye.
A the person ages, the ciliary muscles of the eyes weakens and as a result the lens contracts and the formation of the image takes place behind the retina instead of forming at the retina.
Thus the near point also increases and the refractive power becomes smaller.
Answer:
1J
Explanation:
Work done = force × distance
1 × 1 = 1
Work done = 1J
J = Joules
