______________________________

Answer: The nearest position of an object from a normal human eye so that its image is formed on retina is 25 CM. If the object is placed at a distance less than 25 CM, then the blurred image of the object is formed on retina as the focal length of a lens cannot be decreased below a certain limit. Hence we cannot see it clearly.

The force of replusion between two like charged particles will increase if​
Alex_Xolod [135]

Answer:

The distance of separation is decreased

Explanation:

From Cuolomb's law, we know that the strength of charge is inversely proportional to the distance of separation between the charges. To mean that increasing the distance let's say from 2m to 3 m would mean initial strength getting form 1/4 to 1/9 which is a decrease. The vice versa is true hence the force of repulsion can increase only when we decrease the distance of separation.

It takes Harry 34 s to walk from x1 = -11 m to x2 = -54 m .
miss Akunina [59]
Missing question:
"<span>What is his velocity? Please answer using two sig figs in m/s."

Solution
The relationship between velocity (v), space (S) and time (t) is
</span>v= \frac{S}{t}
<span>The space covered by Harry is
</span>S=x_1 - x_2 = -11 m-(-54 m)=43 m
<span>and so the velocity is 
</span>v= \frac{43 m}{34 s} =1.26 m/s<span>
</span>
