An electron is moving directly toward you in a horizontal path when it suddenly enters a uniform magnetic field that is either v

blagie [28]

Answer:

To your left

Explanation:

The direction of the force exerted on charged particle due to a magnetic field is given by the right-hand-rule, where:

- The index finger indicates the direction of motion of the electron

- the middle finger gives the direction of the magnetic field

- the thumb gives the direction of the force if the particle is positively charged - otherwise, the direction is reversed

in this case, we have an electron (so, a negatively charged particle):

- The direction of motion (index finger) is horizontal, toward you

- The electron begins to curve upward as it enters the field, so this means that the force exerted on the electrons is upward --> the thumb must point downward (because the electron is negatively charged)

- The index finger gives us the direction of the magnetic field: therefore, to your left.

A parallel-plate capacitor with circular plates of radius R is being discharged. The displacement current through a central circ

Dvinal [7]

Answer:

The discharging current is $I_d = 36.8 \ A$

Explanation:

From the question we are told that

The radius of each circular plates is R

The displacement current is $I = 9.2 \ A$

The radius of the central circular area is $\frac{R}{2}$

The discharging current is mathematically represented as

$I_d = \frac{A}{k} * I$

where A is the area of each plate which is mathematically represented as

$A = \pi R ^2$

and k is central circular area which is mathematically represented as

$k = \pi [\frac{R}{2} ]^2$

$I_d = \frac{\pi R^2 }{\pi * [ \frac{R}{2}]^2 } * I$

$I_d = \frac{\pi R^2 }{\pi * \frac{R^2}{4} } * I$

$I_d = 4 * I$

substituting values

$I_d = 4 * 9.2$

$I_d = 36.8 \ A$

there are two types of waves: electromagnetic and mechanical. can either type travel regardless of the presence of a medium?

Dmitry_Shevchenko [17]

Yes, electromagnetic can travel without medium.

Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us.

Waves in water and sound waves in air are two examples of mechanical waves.

Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma.

Matter that waves are traveling through is called a medium.

These mechanical waves travel through a medium by causing the molecules to bump into each other, like falling dominoes transferring energy from one to the next.

Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves.

On the other hand electromagnetic waves don't require medium for its propagation.

An easy example would be light which is an EM wave reaches earth even though space has no medium.
