Answer:
No Refraction takes places
Explanation:
When light travels from one medium to another at an angle of incidence 0 degree then no refraction takes place .
It is because according to Refraction law
sini =
sinr
where
are the refractive index of medium of incidence and medium of refraction .
When i = 0 , left side of the equation becomes 0 and thus r (angle of refraction) must be zero. So No refraction takes place
Answer:
A Pareto chart, named after an Italian economist, combines a bar chart with a line graph. The bar chart is different from a histogram in more than one way. For example, the vertical bars need not touch one another as per a histogram

Explanation:
The two spheres have opposite charges.
<h3 /><h3 /><h3>What are types charge?</h3>
- A charge can be negatively charged or positively charged.
- When two charges have opposite signs, that is positive and negative signs, the two charges will attract each other.
- When the two charges have the same sign, it causes repulsion.
When a positive charge points downwards ↓ and the negative charge points upwards ↑, this causes attraction and shows that the two charges are different.
Thus, we can conclude that the two spheres have opposite charges.
