A magnetic field is used to suspend a wire of mass 0.05 kgkg and length 0.16 mm . The wire is carrying a current of 11 AA . What

pochemuha

Answer:

$B=0.27840\ T$

Explanation:

Given:

mass of the wire, $m=0.05\ kg$

length of the wire, $L=0.16\ m$

current in the wire, $I=11\ A$

Now form the Lorentz force we know that every current carrying wire experiences a magnetic force on it due to the magnetic field components perpendicular to it.

Mathematically given as:

$F=I.L\times B$

$m.g=I.L\times B$

here: we nee to balance the gravitational force on the mass.

$B=$ magnetic field

$0.05\times 9.8=11\times 0.16\times B$

$B=0.27840\ T$

This magnetic field must be perpendicular to the direction of current in the wire and the these two directional quantities must lie in a plane normal to the direction of gravity according to the Fleming's left hand rule.

You are taking a picture of a giraffe that is standing far away from you. The image is just too small, so you swap the 60-mm-foc

vfiekz [6]

Explanation:

Given that, you are taking a picture of a giraffe that is standing far away from you. The image is just too small, so you swap the 60-mm-focal-length lens in your camera for a 960 mm telephoto lens such that,

$m_1=960\ mm$

$m_2=60\ mm$

We need to find the the factor with which the size of the image increases. It can be calculated by taking ratios of both $m_1\ and\ m_2$

So, $\dfrac{m_1}{m_2}=\dfrac{960}{60}$

$\dfrac{m_1}{m_2}=16$

So, the size of image increases by a factor of 16. Hence, this is the required solution.

Answer:

Answer labeled B : 2,304,000 N

Explanation:

Recall the formula for the electric force:

$F_e=9\,\,10^9\, \, \frac{q_1*q_2}{d^2} \\F_e=9\,\,10^9\, \, \frac{8\,10^{-4}*8\,10^{-4}}{0.05^2} \\F_e=2,304,000\,\,N$

which agrees with answer B provided.

What causes diffraction that results in a fuzzy glow around a full moon?

bagirrra123 [75]

Well, that's not actually "diffraction".

The fuzzy edge of the moon, and the added glow that's sometimes seen
around it, are all effects caused by the light passing through air before it
reaches you.

This gives you some idea of why astronomers go to such effort and
expense to get their telescopes above as much of the atmosphere as
possible ... placing all serious observatories on mountaintops, and even
putting telescopes in orbit. It's all because the air does such a job on the
light that's trying to shine through it. We have to make do with whatever's
left over after that.
