love history [14]

So we want to know what are loops of gas on the Sun that link different parts of sunspot regions together. A large and bright gaseous feature that extends from the surface of the Sun that links different parts of sunspot regions together is called Prominence. They are on the Suns surface in the photosphere and they extend outwards into the Corona.

Calculate the amount of charge necessary to exert a force of 35 N in an electric field of 300 N/C.

densk [106]

Answer:

The amount of charge is "0.117 C" i.e., option A.

Explanation:

The given values are:

Force,

$\vec{F}$ = 35 N

Electric field,

$\vec{E}$ = 300 N/C

Charge,

q = ?

As we know,

⇒ $\vec{F}=q\vec{E}$

On substituting the given values in the above formula, we get

⇒ $35=q\times 300$

⇒ $q=\frac{35}{300}$

⇒ $q=0.117 \ C$

Does a spherical bubble of air in a volume of water act to converge or to diverge light passing through it?

viktelen [127]

Answer:

diverge light

Explanation:

The refractive index of water is greater than that of air which means that water is more denser than air and also air is optically rarer than water.

Thus,

When the beam of the light is incident from the air to the bubble which contains air, the light bends away from the normal and then the light travels from air to water and bend towards the normal. Thus, the light is first bend away from the normal and then towards the normal which means that the bubble has diverging nature. The light will likely to diverge.
