Why is it important to understand forces?

Physics

yanalaym [24]3 years ago

If people never learned forces, there would be a major gap in the world and how it works, let alone in physics...
as much as you don't wanna admit it, force is everywhere and you see it if not use it EVERY day in your life, something as simple as driving a car down the street or too school, your using force of your wheels to move your car, which is moving you

How do you calculate the fundamental frequency of a pipe?
ankoles [38]

This depends on whether the pipe is closed or open ended.

The fundamental frequency of a pipe is the simplest, smallest portion of a wave that can fit into a pipe. At the open end of a pipe, there is always an antinode - an area with maximum air movement.

If it is an open ended pipe, there is an antinode at each end, meaning that the length of the pipe is equal to 1/2 <span>λ </span>. Manipulating the formula <span><span>v=fλ</span> </span> to solve for the fundamental frequency leaves us with <span><span>f=<span>v/<span>2L</span></span></span> </span> in an open ended pipe.

Two deuterium nuclei, H, fuse to produce a tritium nucleus, H, and a hydrogen nucleus. A neutral deuterium atom has a mass of 2.
Nesterboy [21]

<u>Answer:</u> The amount of energy released in the process is 4.042 MeV.

<u>Explanation:</u>

The chemical reaction for the fusion of deuterium nucleus follows the equation:

_1^2\textrm{H}+_1^2\textrm{H}\rightarrow _1^3\textrm{H}+_1^1\textrm{H}

Atomic mass of the nucleus also contains some mass of the electrons.

Mass of electron in MeV/c^2 is 0.511MeV/c^2

  • <u>Calculating the mass of deuterium nucleus:</u>

m(_1^2\textrm{H})=(2.014102u)\times (931.494MeV/c^2.u)-\text{Mass of electron}

So, initial mass of the reaction = 2[(1876.124MeV/c^2)-(0.511MeV/c^2)]=3751.226MeV/c^2

  • <u>Calculating the mass of tritium nucleus:</u>

m(_1^3\textrm{H})=(3.106049u)\times (931.494MeV/c^2.u)-\text{Mass of electron}

m(_1^3\textrm{H})=(3.106049u)\times (931.494MeV/c^2.u)-(0.511MeV/c^2)=2803.921MeV/c^2

So, final mass of the reaction = 2803.921-[(1.007267u\times 931.494MeV/c^2.u)]=3747.184

Difference between the masses of the nucleus:

\Delta m=m_{initial}-m_{final}\\\\\Delta m=(3751.226-3747.184)MeV/c^2=4.042MeV/c^2

Energy released in the process is calculated by using Einstein's equation, which is:

E=\Delta mc^2

Putting value of \Delta m in above equation, we get:

E=(4.042MeV/c^2)\times c^2\\\\E=4.042MeV

Hence, the amount of energy released in the process is 4.042 MeV.
