Answer: 32pF
Explanation:
The <u>capacitance</u> of a parallel plate capacitor is given by the following equation:
Where:
is the <u>electric constant when the dielectric material is vacuum</u>
is the <u>area of each plate</u>
is the <u>separation distance between both plates</u>
This is the capacitance when the dielectric is vacuum.
Now, we can calculate the capacitance , when we have a dielectric material with a dielectric constant :
Finally:
True.
Conductivity is the ability to transmit heat, electricity or sound. Conductivity is a physical property.
A physical property is one which can be measured or observed without changing the composition or identity of a the substance.
Conductivity is a physical property because the composition of the substance does not change.
A copper wire is still a copper wire when it is conducting electricity. Like wise, an aluminum rod is still an aluminum rod when heated. It is conducting heat but the heat does not change it, it is still an aluminum rod during the whole process.
They continued to study its behavior and decided that it probably travels<span> in both waves and particles.

Answer:
"The idea behind thermal expansion is that gases expand as the temperature increases. If you have a balloon and you heat up the contents, the balloon will get larger. Scientists use the term ideal gas law to describe this activity. Liquids expand and contract, too, but there is a lot less change than in gases."
I don't know if this is what u meant, but, hope this helps :3
