All of these things were seen in formal experiments by the 19th century. But some of them are easy to see in your own home. It's obvious that light can reflect - you just have to look in a mirror. Light bounces off the mirror and goes into your eye so you can see yourself. It's also obvious that light can refract: All you have to do is put a spoon in a large glass of water and watch how the spoon appears to bend.
That happens because the light is bending as it moves between air and water. Both of these things can be seen even more clearly in a laboratory using beams of light or lasers.
<span>First you need to </span>find<span> the slope of the </span>two lines<span>. Because they are </span>parallel<span>, they are the same slope, so if you </span>find<span> the slope of one, you have the slope of both. Start at the \begin{align*}y-\end{align*}intercept of the top </span><span>line.</span>
Here are a list of items I found.
some brushes
a armature
a permanent magnet
some slip rings
So, C = kE°A/d
putting the values,
C
= 3.8 × 8.85×10^(-12) × 3.14×1.5×1.5 × 10^(-6)/0.43 × 10^(-3)
so, 1.02 × 10^(-13)
so the most appropriate answer is 2 ...that is
1.4 × 10^(-13) ....answer !!
Answer:
you need to multiply the momentum and the mass
