It’s c
Because velocity; just like speed will be distance over time
However on this case it’s displacement over time
Anyway in case ur wondering ,
the only difference between distance and displacement is that displacement requires a direction
so
100m/4s
=25 m/s to the east since the direction is already mentioned in question
Answer:
Gold is soft metal, hard metal, malleable, and ductile.
Explanation:
1- Red color has the longest wavelength. Red light belongs to the visible spectrum of light and the wavelength of visible spectrum ranges from 700nm to 400nm, from red to violet respectively.
2- Gamma rays, x-rays, visible light and radio waves are all types of electromagnetic radiations. Electromagnetic radiations contain visible light, radio waves, gamma rays and x-rays. These radiations has varied electric and magnetic fields.
3- The fact that light can exert a pressure on matter suggests that it is made up of photons.
It is designed to protect good bacteria in the gut.
I think release of chlorofluorocarbons (cfcs) is most closely associated with sunburns. CFCs are green house chemicals that are more potent than the current greenhouse chemicals such as carbon dioxide and methane,and therefore should not be released to the atmosphere. CFCs release free chlorine which is responsible for destabilizing and destroying the ozone layer, which absorbs most of the UV radiations.
