Answer:
5.3 cm
Explanation:
This question is an illustration of real and apparent distance.
From the question, we have the following given parameters
Real Distance, R = 8.0cm
Refractive Index, μ = 1.5
Required
Determine the apparent distance (A)
The relationship between R, A and μ is:
μ = R/A
i.e.
Refractive Index = Real Distance ÷ Apparent Distance
Substitute values in the above formula
1.5 = 8/A
Multiply both sides by A
1.5 * A = A * 8/A
1.5A = 8
Divide both side by 1.5
1.5A/1.5 = 8/1.5
A = 8/1.5
A = 5.3cm
Hence, the letters would appear at a distance of 5.3cm
They have to have a positive charge and negative so then thats what u get
Answer: c. A person who gains unauthorized access to digital data
Explanation:
Answer rain gauge measures rain shadow units millimetres
Radius of nuclei is given by formula
now we can say volume of the nuclei is given as
now the density is given as
density = mass / volume
mass of nuclei = mass of neutron + mass of protons
Now density is given as
here we know that
= 1.2 fm
So from above we can say that density of all nuclei is almost same.
