How do you know that electromagnetic waves can travel thought a vacuum?
Light being electromagnetic wave is able to traverse right from Sun to the Earth through vacuum existing in between the two. This confirms electromagnetic wave can traverse through free space. Now free space itself is a medium but not a material medium.
How do you know the speed of a electromagnetic wave in a vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Is graphite a ceramic material?
Graphite isn't a ceramic material itself, however it can be made into a ceramic material

Is resistivity of a material depends upon the dimensions of a material?
No. Resistivity is a property of the material itself and does not change no matter how much of that material you have. Resistance, however, does depend on the dimensions of the material.
Why is it a bad idea to make an electromagnetic crane out of a magnetically hard material?
it will stick to itself!
Does lava get hotter or colder?
Lava (and any other material) will cool down if it is surronded by material that is at a lower temperature than itself and heat up if the surrounding material is hotter. By definition, lava is molten rock that has been erupted onto the earth's surface. As such it is surrounded by material that is at a much lower temperature than itself so will lose heat and so decrease in temperature.

Relation between melting temperature and sintering temperature?
The idea of sintering is heating a powder until it is hot enough to stick to itself, then reshaping it and letting it set. The temperature used is always lower than the melting point of the material.
Does light conduct electricity?
Light is itself a form of electromagnetic radiation.
Can you assign temperature to a vacuum?
Answer Yes, you can. I think the answer is no. A physical object in a vacuum can have some energy/heat in it, and the energy associated with electromagnetic radiation can have energy/heat associated with it, but the vacuum itself cannot. ______________________________________________________________________ There is no such thing as a vacuum.
What determines the electrical resistance of a material?
The material itself and the Gage
Are half lives affected by temperature?
In general, temperature does not affect the half-life of a substance, as it is a characteristic property of the material itself. However, extreme conditions such as very high temperatures can potentially alter chemical reactions and impact half-life.
How do you know the speed of an electromagnetic wave in vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
