Answer:
What do you want me to answer here?
Explanation:
Given :
Potential ,
![P=644 \times 10^6\ V\\ \\P=6.44\times 10^8\ V](https://tex.z-dn.net/?f=P%3D644%20%5Ctimes%2010%5E6%5C%20V%5C%5C%20%5C%5CP%3D6.44%5Ctimes%2010%5E8%5C%20V)
Uniform magnetic field , B = 0.02 T .
Mass of proton ,
.
Charge on proton ,
.
Also , velocity of proton is perpendicular to magnetic field .
To Find :
The radius of the proton's resulting orbit .
Solution :
Now , when velocity is perpendicular to magnetic field radius of orbit is given by :
Putting all given values above :
![r=\sqrt{\dfrac{2\times 6.44\times 10^8\times 1.67\times 10^{-27}}{1.6\times 10^{-19}\times 0.02^2}}\\\\r=183.33 \ m](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%5Cdfrac%7B2%5Ctimes%206.44%5Ctimes%2010%5E8%5Ctimes%201.67%5Ctimes%2010%5E%7B-27%7D%7D%7B1.6%5Ctimes%2010%5E%7B-19%7D%5Ctimes%200.02%5E2%7D%7D%5C%5C%5C%5Cr%3D183.33%20%5C%20m)
Therefore , radius of orbit is 183.33 m .
Hence , this is the required solution .
The force applied to pull the box up the ramp acts parallel to the incline is 8N
The force applied to pull the box is expressed as:
![F_N = F_m + F_f](https://tex.z-dn.net/?f=F_N%20%3D%20F_m%20%2B%20F_f)
Fm is the moving force
Ff is the force of friction
Get the moving force and frictional fice
![F_m = 10sin30^0 = 5N\\F_f = 3N](https://tex.z-dn.net/?f=F_m%20%3D%2010sin30%5E0%20%3D%205N%5C%5CF_f%20%3D%203N)
The force applied to pull the box up the ramp acts parallel to the incline = 5N + 3N = 8N
Hence the force applied to pull the box up the ramp acts parallel to the incline is 8N

Answer:
B) electrons
Explanation:
When charge is transferred by friction, induction or conduction, the charge carriers are the electrons.
In fact, protons and neutrons are found within the nucleus of the atoms, so they are tightly bound and they cannot be easily gained/given off. On the contrary, electrons are found in the electron clouds around the nucleus, so atoms can more easily gain/lose electrons, which become free and can be passed by an object to another.
The three methods of charging are:
- Friction: by rubbing two objects together, electrons may be transferred from one to another
- Induction: by moving a charged object closer to a neutral object, opposite charges in the neutral object migrate towards the opposite ends of the object, and if the object is connected to the ground, the charges of one polarity leave the object, leaving the object charged
- Conduction: by putting a charged object in contact with a neutral object, electrons can be transferred from the charged object to the neutral one
