A converging lens<span> (or convex </span>lens<span>) is curved on both sides. This means the light rays coming out of it come together at a point – they converge. Diagram of how a </span>lens<span> works. The point at which the light rays meet is called the focal point.sooo.......D</span>

<h2>The atomic mass of silicon is 28.0855</h2>
as per the question charlie runs to the store which is 4 km away
hence the total distance covered [S] is 4 km
he takes 30 minutes to reach the store.
hence the total time taken [t] = 30 minutes=0.5 hour
We have to calculate the average speed.
the average speed[v]=
=
=8 km/hour
then we have to calculate the total distance traveled by charlie in 1 hour.
the distance covered S=
=8 km/hour ×1 hour
=8 km
Hence the average speed of charlie is 8 km/hour and he covers a distance of 8 km in 1 hour.
