Answer:
Surface tension is a force that pulls particles at the exposed surface of a liquid toward other liquid particles. Surface tension explains why water forms droplets, like the water droplet that has formed on the leaky faucet pictured in the Figure below.
Answers to wave questions:
1) trough - lowest point of the wave.
2) crest - highest point of wave.
3) amplitude - distance from rest position to the crest or thoughs.
4) wavelenght - distance from two consecutive crest or troughs.
5) rest position - the flat line running through middle of the wave.
<h2>
Answer</h2>
The answer is 38.05 years
<h2>
Explanation</h2>
To solve this question, we should convert the given seconds to the year.
So,
Number of seconds in a year =
Seconds the man lived = .2 * 10^9
How many years, he lived = ?
Here a unit method will be applied as
Total years the man lived=
Total years the man lived = 38.05 years
As year long drought could be the most damaging and ravishing one that could happen to us
The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.
According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.
Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.
