Answer:
Neutrons are the particles which are present in the nucleus of an atom. These have a neutral charge, means that the don't have a positive charge like proton or a negative charge like an electron, but these are far more dense than electrons and protons. Under normal reaction, neutron may seem to just exist, as usually electrons are the particles which forms bonds or breaks them.
However, Neutrons play an important role in the weight and Radioactive properties of a material. During radioactive decay, which occurs in radioactive elements, the nucleus of an atom breaks down and releases energy and matter, which is primarily due to the knocking out of a neutron. These knocked out neutrons forms the basis of the nuclear fission and fusion reactions.
Answer:
Explanation:
The definition of the intensity in terms of power is given by:
Where:
- P is the power
- A is the area
If the sound emits uniformly in all directions and that there are no reflections, we can assume the geometry of the wave sound is spherical.
Let's recall the area of a sphere is
To the first location we have:
and to the second location we have:
Now, we can divide each intensity to find the second intensity.
I hope it helps you!
⭐Hey
⭐Here we can use the formula for the body that is in free fall state. .
⭐that is
↪V = underoot 2*g*h
↪So the velocity will be ...
↪V = underoot 2 * 10 * 100
↪V = underoot 2000
↪V = 20 *underoot 5
↪V = 20 ( 2.23)
↪V = 44.6 m/s
