All fluids exert pressure like the air inside a tire. The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions.

Answer:
Night vision is the ability to see in low-light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range.
Answer:
Explanation: Two pith ball will repel each other . they will remain balaced due to tension in the spring whose one component balances the weight and the other balances the repulsive force on each.
The gravitational force will be balanced by T cos 27.33 and the electrostatic repulsive force will be balanced by T sin27.33
So
Fg =T cos 27.33
= .55 X .888
= .49 N
Fq = T sin27.33
=.55 x .459
= .25 N.
