Yes.
The more closely packed molecules are in a medium, the faster sound travels through the medium, so sound travels slowest through a gas under low pressure.
Because electricity is the movement and flow of electrons, which are matter. Since they are matter, they cannot reach the speed of light.AnswerBy the 'speed of electricity' you presumably mean the 'speed of charges through a conductor'? (Remember 'electricity' is not a quantity!). The answer is that they move through a conductor v-e-r-y slowly -for normal conductors, just a fraction of a millimetre per second!
That completely depends on what "slowly" means to you.Sound propagating through iron is quite slow compared to the speed of lightin vacuum, but is substantially faster than the same sound in air.
Molecules making up the air are far apart compared to the molecules making up any solid medium. As solids provides very less inter and inter molecular space, light often travels slowly through solid medium. Refractive index of air is 1.

a circuit
because electric charges move to them more slowly
Yes.
The more closely packed molecules are in a medium, the faster sound travels through the medium, so sound travels slowest through a gas under low pressure.
the material in the astehnosphere can flow slowly and the lithosphere flows on top of the astenosphere HOPE I HELPED!!
Electrons in an active circuit either drift slowly, or just jiggle back and forth in one place.
Yes, the electric car was invented a long time ago. The first electric car came about in 1899. It slowly evolved from there into what the modern car is now.
Gas heaters are slowly leaving the industry and are being replaced by electric heaters, which are created by Chromalox. However, by using an electric heater, electric bills get expensive.

It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
It is an example of heat transfer by convection. Material heated by the outer core slowly moves toward the surface through the solid but plastically-mobile mantle.
