Aluminum metal is a good example of conductor of electricity while glass and paper are good example of insulators.
<h3>What is a conductor?</h3>
A conductor is material that allows easy passage of electric current through the.
<h3>Examples of conductors</h3>
All metals are good examples conductors. such as aluminum, iron, silver, etc.
<h3>What is a non conductor?</h3>
A non conductor or insulator is a material which does not allow easy passage of electric current through them.
<h3>Examples of insulators</h3>
Thus, aluminum metal is a good example of conductor of electricity while glass and paper are good example of insulators.

Answer
Given,
Magnetic field, B = 0.0000193 T
speed, v = 121 m/s
mass of electron, m = 9.11 x 10⁻³¹ Kg
charge of electron, q = 1.6 x 10⁻¹⁹ C
radius of the electron path, r = ?
r = 3.64 x 10⁻⁵ m
We know frequency is inverse of time period
d = v t
t = 1.889 x 10⁻⁶ s.
now, frequency
An example of the use of expansion of materials when they are heated is in
Thermometers. Thermometer is an instrument which is used to measure the
temperature of a place.
It contains mercury which expands as temperature increases. This is used
to accurately determine the temperature of an object.
The disadvantage of expansion of materials when they are heated can be
seen in roads as there is expansion of the surface as a result of heat
exposure leads to roads being rough thereby incurring more costs for
repairs.

Answer: False
Explanation: Mass is a measure of the amount of matter in an object.
Difference between an inherited trait and an acquired trait is that an inherited trait is a trait inherited from a family, such as your eye color or hair color, while a acquired trait is something that you learned yourself such as learning how to read.
