Answer:
a).![$3.99 \times 10^5 \ v/m$](https://tex.z-dn.net/?f=%243.99%20%5Ctimes%2010%5E5%20%20%5C%20v%2Fm%24)
b). 2.9925 kV
Explanation:
Given :
For mass spectrometer
The magnetic field = B
B = 0.105 T
a). Given speed, v = ![$3.8 \times 10^6 \ m/s$](https://tex.z-dn.net/?f=%243.8%20%5Ctimes%2010%5E6%20%5C%20m%2Fs%24)
We known
![$\frac{E}{B}=v$](https://tex.z-dn.net/?f=%24%5Cfrac%7BE%7D%7BB%7D%3Dv%24)
∴ ![$E= 3.8 \times 10^6 \times 0.105$](https://tex.z-dn.net/?f=%24E%3D%203.8%20%5Ctimes%2010%5E6%20%5Ctimes%200.105%24)
![$=3.99 \times 10^5 \ v/m$](https://tex.z-dn.net/?f=%24%3D3.99%20%5Ctimes%2010%5E5%20%20%5C%20v%2Fm%24)
b). Now spectrometer, d = 0.75 cm
![$d=0.75 \times 10^{-2} \ m$](https://tex.z-dn.net/?f=%24d%3D0.75%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20m%24)
We known
![$E=\frac{V}{d}$](https://tex.z-dn.net/?f=%24E%3D%5Cfrac%7BV%7D%7Bd%7D%24)
![$V = E\times d$](https://tex.z-dn.net/?f=%24V%20%3D%20E%5Ctimes%20d%24)
![$V = 3.99 \times 10^5 \times 0.75 \times 10^{-2}$](https://tex.z-dn.net/?f=%24V%20%3D%203.99%20%5Ctimes%2010%5E5%20%5Ctimes%200.75%20%5Ctimes%2010%5E%7B-2%7D%24)
![$V = 2.9925 \times 10^3 \ V$](https://tex.z-dn.net/?f=%24V%20%3D%202.9925%20%5Ctimes%2010%5E3%20%5C%20V%24)
= 2.9925 kV
Answer:
We will use Potential Energy Formula
Potential Energy = mass × gravitation × height
PE = 0,55 × 10 × 4
PE = 22 J (A)
Explanation:
Fnet = 12.0N - 5.0N = 7.0N
a = Fnet/m = 7.0N/6.5kg = 1.07m/s².
By definition we have to:
Applied force: It is the external force that acts directly on a body.
Therefore, we can say that if you have an object and push it towards yourself, you are exerting an external force on the object.
This external force was not acting on the object previously, therefore, it is a force that you are applying at that moment.
Answer:
you exert an Applied Force on an object when you pull it towards you
A. Applied Force
Thank you for posting your question your question here. Below is the solution:
time = 3.00 / 1.75
<span>time = 1.714 </span>
<span>now </span>
<span>distance = (initial velocity + final velocity) / 2 * time/ 1 </span>
<span>Hence</span>
<span>3 = ( 1.75 + final velocity) / 2 * 1.714 </span>
<span>3.5 - 1.75 = final velocity </span>
<span>Therefore, the final velocity is 1.75 m /s</span>
