The particles will move faster and further apart. There will be more energy in the particles due to the heat.
a hearing aid.
it doesn't get in contact with fluids (like contact lenses) and doesn't get implanted, so it got not much to do with the immune system
Generally, metals GIVE AWAY their outer shell electrons, hydrogen usually GAINS an electron in order to become stable.
Non metals are electronegative in nature whereas metals are electropositive. A non-metal accepts electron and gains negative charge whereas metals lose eletrons and gains positive charge. Hence correct answer is non-metals. Hope this helps!
The velocity would be 0.5 i think
