What is friction and explain
Answers
If we avoid friction, we move faster.
But, in some cases, friction is also good. It is used in car brakes, when something rubs on the wheels to make the wheels stop rolling, or rotating.
Ice skates may be another thing. They provide a little friction on the blades, to be able to stop and to be able to move.

The period is 1/5 second, and the frequency is 5 Hz.
Explanation:
Let's start by reviewing some definitions about waves:
- The period of a wave is the time taken for the wave to make one complete cycle. It is indicated with T and it is measured in seconds (s)
- The frequency of a wave is the number of complete cycles made by the wave in one second. It is indicated with f and it is measured in Hertz (Hz). It is equal to the reciprocal of the period:
where f is the frequency and T is the period.
In this problem, we have a wave that passes a given point five time per second. This means that the number of oscillations per second is five, and so its frequency is:
It follows than the period of the wave is:
Therefore, the correct statement is
The period is 1/5 second, and the frequency is 5 Hz.

Q 1. In transverse waves the vibration is perpendicular to the direction of travel.
Q 2. In longitudinal waves the vibration is parallel to the direction of travel.
Q 3. Longitudinal waves contain compressions and rarefactions when they travel around.
Q 4. A transverse wave is produced when you move one end of a
horizontal spring up and down.
Q 5. Every type of wave has a wavelength.
1. The vibration is perpendicular to the direction of travel of transverse waves.
2. The vibration is parallel to the direction of travel of longitudinal waves.
3. Compression waves contain compressions and rarefactions.
They are longitudinal waves.

If you only asked me what does an animal need to survive in my house,
I couldn't answer that one either, until you tell me what animal you're
talking about.
Now you want to talk about aliens, of which #1): We have no evidence
that they even exist, and #2): If they do exist,we have no idea what kind
of a planet they live on, and #3): We have no idea what the environment
might be like on that planet.
So, to answer your question, I would say this:
In order to survive on Jupiter, an alien species would need exactly the
same things that Earthly humans would need there ... They would need
some set of materials and devices that could be used to duplicate the
conditions of atmosphere, temperature, pressure, gravitation, and
radiation in which their species evolved and to which it adapted, in
whatever place they came from.
Answers
The answer would be a longitudinal wave.
