What is the period, in seconds, that corresponds to each of

An experimentalist fires a beam of electrons, creating a visible path in the air that can be measured. The beam is fired along a

gtnhenbr [62]

Answer:

Velocity of the electron in the beam.

Radius of the circulating electrons due to the magnetic field.

Explanation:

We have a Mathematical expression for the force on a moving charge in a magnetic field as:

$F=q.v.B.sin \theta$ ...........................(1)

where:

q= charge on the particle in coulomb

v= velocity of the charge projected into the magnetic field

B= intensity of the magnetic field in tesla

$\theta$ = angle between the velocity and direction of magnetic field

For the forces on rotating mass we have the formula:

$F=m.\frac{v^2}{r}$ ..........................................(2)

where:

m= mass of the charged particle

v= velocity of projection of charge into the magnetic field

r= radius of the path traced by the charge in the magnetic field

From eq. (1) and (2) we can calculate the magnetic field .

Now,

Using Ampere's Law we have:

$B = \frac{\mu_0 .I}{2 \pi r}$

where:

I= current in the wire

$\mu_0=$ The permeability of free space.

r= radial distance from the current carrying wire( in this case it is same as the radius of the circular path)

What can destroy stuff yet does not have any mass

Artist 52 [7]

If energy could be created or destroyed, all of our ideas of how the world works ... Historically, of course not all the forms of energy were known to begin with. ... too messy or complicated to make sense, we would have had to give up the law. ... can be converted into rest mass and back again (particle physicists do this every )

A conducting sphere with radius R is charged until the magnitude of the electric field just outside its surface is E. The electr

dusya [7]

Answer:

he correct answer is V = ER

Explanation:

In this exercise they give us the electric field on the surface of the sphere and ask us about the electric potential, the two quantities are related

ΔV = ∫ E.ds

where E is the elective field and normal displacement vector.

Since E is radial in a spray the displacement vector is also radial, the dot product e reduces to the algebraic product.

ΔV = ∫ E ds

ΔV = E s

since s is in the direction of the radii its value on the surface of the spheres s = R

ΔV = E R

checking the correct answer is V = ER
