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:
Acceleration
Explanation:
Acceleration has units of length per time squared.
Mass is a property of an object, a cloud of gas, a puddle of liquid, or a lump of goo, and doesn't necessarily change when the object moves to a different location or environment. It depends only on the object itself.
Weight is completely a product of what else is in the nearby location,so it can easily change. It's the result of the gravitational forces between <em>two</em> objects . . . the first one with the constant mass, and <em>another one</em> that also has mass. The forces between them, and therefore the weight, depend on <u>both</u> masses, AND on the distance between them.
Answer:
<h2>30 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question
force = 6 N
distance = 5 m
We have
workdone = 6 × 5 = 30
We have the final answer as
<h3>30 J</h3>
