The result of the Sun's light being refracted when it is
high in the sky around noon is blue, indigo and violet are strongly bent that
mostly skim through the upper atmosphere making the sky appear blue. The
refraction of the light during noon makes the sky blue.
Explanation:
It is given that,
Electric field strength, E = 20,000 N/C
Spacing between parallel-plate capacitor, d = 1 mm = 0.001 m
Initial velocity of electron, u = 0
Let v is the electron’s speed when it reaches the positive plate. The force acting on the electron is :
Also, 
Using third equation of motion as :
v = 2649528.2599 m/s
or
So, the velocity of the electron when it reaches the positive plate is 
. Hence, this is the required solution.
Use the pH scale. When vinegar is mixed with water, the pH is 2.4 to 2.6. Baking soda and water has a pH of 9 to 11. this is because baking soda makes water alkaline.
