hope it's help you ok have a good day
<span>the electrons change their energy states and photons in visible spectrum (and infrared spectrum) are emitted.More the losses, more would be the light, but at the same time, more would be the heat generated.So
this necessitates that the metal used should have high resistivity (and
hence high losses), good thermmal conductivity and high melting point.
hope it helps

Answer:
Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume.
I hope it helps.
Have a great day.
Correct answer: A. Alpha particles are 20 times safer than other types of radiation.
Alpha, beta, gamma, and X-rays are the forms of ionizing radiations. Alpha radiations are emitted when an atom emits alpha particles with 2 neutrons and 2 protons. These particles ionize matter due to their charge and mass. Alpha particles cannot penetrate the outer layers of the skin, but when present inside the cell they can be very damaging as they lose their energy within short distances ionizing the matter present around. Therefore, alpha particles cause more damage than other forms of radiations.
