What is semiconductor device that produces electric current through the effect for which its named?

nlexa [21]

The semiconductor device that produces electric current through the effect is termed as transistor.

To find the answer, we have to know more transistor.

<h3>What is transistor?</h3>

Transistors come in two different types: field-effect transistors and bipolar junction transistors.
The formation of two p-n junctions in various configurations, such as n-p-n or p-n-p, results in bipolar junction transistors.
The emitter, collector, and base, or middle region, are the three areas that form in a transistor.
The conductivity of the field-effect transistor, which is based on the conductivity principle, can be changed by an electric field.

Thus, we can conclude that, the semiconductor device that produces electric current through the effect is termed as transistor.

A proton and an electron are moving in the +x direction in a magnetic field in the +z

Aleksandr [31]

Answer:

Explanation:

Force on a moving charge is given by the following relation

F = q ( v x B )

for proton

q = e , v = vi , B = Bk

F = e ( vi x Bk )

= Bev - j

= - Bevj

The direction of force is along negative of y axis or -y - axis.

for electron

q = - e , v = vi , B = Bk

F = - e ( vi x Bk )

= - Bev - j

= Bevj

The direction of force is along positive of y axis or + y - axis.

Why do the heights of the tides change over the course of a month?

Y_Kistochka [10]

Answer:

The heights of the tides change over the course of a month due to -

<u>the position of Sun , Moon and Earth .</u>

Explanation:

Tides are formed due to the gravitational attraction of the sun and the moon on the surface of the Earth .

Since , the Moon is closer to Earth as compared to the Sun , Hence , Moon has greater attraction on Earth than Sun .

Moon plays an important role for producing the Tides .

In every 27.3 days , the Earth and the Moon revolves around the common point .

Therefore , in every 27.3 days , a new tidal cycle forms .

Two types of tides are possible , high tide and low tides .

In a day , two high tide and two low tide occurs ,

And because of the angle of Moon with respect to Earth , the two high tides do not have the same height . same for the case of two low tide .

The height of tides differ in the height on a daily basis .

The extraction of oil from oil shales can be detrimental to the environment mainly because this process requires large amounts o

zheka24 [161]

I believe the correct answer would be A. The extraction of oil shale is detrimental to the environment mainly because the process of extraction requires large amounts of land. Lands are being excavated in order to locate areas which contains the oil. This is not good since it affects ecosystems and destroy habitats.

Convert the number from scientific into standard notation: 5.9 x 10-2

guapka [62]

Move the decimal point to:
Left : (if the exponent of ten is a negative number -) ... OUR CASE HERE (-2)
or to
Right : (if the exponent is positive +).

You should move the point as many times as the exponent indicates.
Do not write the power of ten anymore.

So, standard form is:
Two points to the left {Exponent of Ten is Negative (-2)}
0.059 ... (without the 10)
