In the manufacturing of computer chips, cylinders of silicon are cut into thin wafers that are 3.00 in. in diameter and have a m
Shalnov [3]

Answer: thickness h = 0.014cm

Question: In the manufacturing of computer chips, cylinders of silicon are cut into thin wafers that are 3.30 inches in diameter and have a mass of 1.50 g of silicon. How thick (mm) is each wafer if silicon has a density of 2.33 g/cm 3 ? (The volume of a cylinder is V=πr 2 h )

Explanation:

The volume of a cylinder is

Volume V = πr^2h ....1

The density of a material is

Density D = mass m / volume V

D = m/V ....2

Since m and D are given, we can make V the subject of formula.

V = m/D ....3

From equation 1, we need to derive the thickness h of the cylindrical silicon.

h = V/πr^2 .....4

Substituting equation 3 into 4

h = (m/D)/πr^2 .....5

Given.

mass m = 1.50g

density D = 2.33g/cm^3

radius r = diameter/2 = 3.00in/2 = 7.62/2 cm = 3.81cm

Substituting the given values into the equation

h = (1.5/2.33)/(π ×3.81^2)

thickness h = 0.014cm

Name two units for measuring the diameter of nucleus atom.
Evgesh-ka [11]

The two units for measuring the diameter of nucleus atom are femtometre and metre.

How do you measure the size of the nucleus ?

Nucleus size is expressed in fermi, often known as femtometers. between a lighter and a heavier nucleus. Despite its modest size, the nucleus contains the majority of an atom's mass. The weight or mass of the atom's nucleus and neutrons are determined by neutrons.

femtometre (fm), which equals 10^{-15} metre.

A nucleus' diameter largely depends as to how many particles it contains, from about 4 fm for a light nucleus like carbon to 15 fm for a heavy nucleus as lead.
