The small bang lol, sorry if this is an actual question but i’m pretty sure no one knows the answer- at least i don’t! good luck if it’s an actual question on and assignment or quiz, very sorry. xoxo
Borax, also known as sodium borate, sodium tetraborate,
or disodium tetraborate, is an important boron compound,
a mineral, and a salt of boric acid. Powdered borax is white,
consisting of soft colorless crystals that dissolve easily in water.
Its molecular (chemical) formula is <span>
<span>Na₂B₄O₇·10H₂O or Na₂[B₄O₅(OH)₄]·8H₂O .</span></span>
Answer:
The refractive index of material of prism is 1.06.
Explanation:
Given that,
Angle of prism, A = 40 degrees
Angle of deviation,
We need to find the refractive index of material of prism. We know that the relation between angle of deviation, prism angle and the refractive index is given by :
is the refractive index of material of prism
So, the refractive index of material of prism is 1.06. Hence, this is the required solution.

Explanation:
Answer:
Move further apart
Explanation:
The negative charge on the rod repels the electrons on the cap thus they concentrate at the leaves causing an increase in the amount of charge at the leaves. Since like charges repel, the two leaves of the electroscope move further apart.
Answer:
Explanation:
When a force is applied for time t , it creates impulse . The impulse creates change in momentum .
In the change in momentum = Mvf - 0 = Mvf .
Impulse = FA x t , t is time .
FA x t = Mvf
t = M x vf / FA .
