Answer:
-72\times 10^{-19}C[/tex]
Explanation:
Both electron and proton have the same amount of charge but signs are opposite , electron contains negative charge and proton contain positive charge
Charge on 1 electron = 
So charge on 206 electron 
Charge on 1 proton =
So charge on 161 electron 
So charge of the system = 
Your answer is- amplitudes
A. Air, desk, water. sound travels the slowest through air and the fastest through liquids. solids are somewhere in the middle.
Because fossil fuels are non-renewable resources.
This means, if we run out, we will not be able to reproduce it.
It would be the last that exists. (For oil, it'd be for the next few hundred years.)
Answer: 1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.
2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then
2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.
