Answer:
<em>0.45 N</em>
Explanation:
<em>Let Recall that,</em>
<em> The power formula is: </em>
<em> P = E²/R </em>
Let A = the magnetic field
<em>Let L = length of wire = 9.00cm = 0.09 m </em>
let R = resistance of wire = 0.320 Ω
let v = velocity of the wire = 4 m/s
<em>Let E = across the wire voltage </em>
Let P = the power of the wire = 4.3 W
To Solve for E:
<em>The formula of E = √PR </em>
The Voltage from a magnetic field is given as,
E = vAL
We therefore Use E = E
√PR = vAL
to solve for A,
A= √PR/vL
BA= √4.3(0.32)/(4)(.09) -=0.173
A = 0.173 wA/m²
Let F be the pulling force
Let I be the current in the wire
P = I²R
<em>I = √P/R </em>
F = IAL
F = √P/RAL
F = √4.3/.32(0.173)(.09)
<em>F = 0.45N</em>
Answer:
Magnetic field, B = 0.042 T
Explanation:
It is given that,
Speed of charged particle, ![v=8.2\times 10^3\ m/s](https://tex.z-dn.net/?f=v%3D8.2%5Ctimes%2010%5E3%5C%20m%2Fs)
Angle between velocity and the magnetic field, ![\theta=87](https://tex.z-dn.net/?f=%5Ctheta%3D87)
Charge, ![q=5.7\ \mu C=5.7\times 10^{-6}\ C](https://tex.z-dn.net/?f=q%3D5.7%5C%20%5Cmu%20C%3D5.7%5Ctimes%2010%5E%7B-6%7D%5C%20C)
Magnetic force, F = 0.002 N
The magnetic force is given by :
![F=qvB\ sin\theta](https://tex.z-dn.net/?f=F%3DqvB%5C%20sin%5Ctheta)
B is the magnetic field
![B=\dfrac{F}{qv\ sin\theta}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7BF%7D%7Bqv%5C%20sin%5Ctheta%7D)
![B=\dfrac{0.002}{5.7\times 10^{-6}\times 8.2\times 10^3\times sin(87)}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B0.002%7D%7B5.7%5Ctimes%2010%5E%7B-6%7D%5Ctimes%208.2%5Ctimes%2010%5E3%5Ctimes%20sin%2887%29%7D)
B = 0.042 T
So, the strength of the magnetic field is 0.042 Tesla. Hence, this is the required solution.
The momentum does not change because he is going the same speed just a different way.
Answer: The recently discovered Eris orbits the Sun every 557 years. ... 67.69 AU; since the average distance for Pluto from the Sun is 39.3 AU then the distance is nearly twice.
