Ohm's Law => V = I/R where
V stands for voltage,
I stands for Current
R stands for resistance.
ATQ
we know V = 9 volts
and R = 1.5 ohm's
so we need to find I.
Lets modify our formula little bit
we know V = IR which we can write as I = V/R
so lets substitute the values in the formula.
I = 9/1.5
I = 6 A
Correct Option is A.
We are asked to solve for the index of refraction and the formula is n = c/v where "n" represents the index of refraction, "c" represents the speed of light in the vacuum while "v" represents the speed of another medium.
In the problem, we have the given values below:
c = 3 x 10^8 m/s
v = 2 x 10^8 m/s
n =?
Solving for n, we have the solution below:
n = 3x10^8 / 2x10^8
n = 1.5
The answer is 1.5 for the index of refraction.
Answer:
It reduces the melting point due to a defect in the arrangement of the crystal lattice.
Explanation:
The presence of impurities creates a disorderliness in the uniformity of the crystal structure. It lowers the melting point by a few degrees because it becomes easier to overcome the intermolecular force of attraction.
It makes the array of crystals disordered.
Lattice is a long chain three-dimensional arrangement of the molecules, atoms or ions in a crystal structure.
