La intensidad de corriente que circula por un conductor es 2μA. ¿Que tiempo demoraran 5x1013 electrones en cruzar una determinad

VikaD [51]

Answer:

t = 4 seconds

Explanation:

The question is "The intensity of current flowing through a conductor is 2μA. How long will it take 5x1013 electrons to cross a certain cross section of the conductor? "

Current, $I=2\ \mu A=2\times 10^{-6}\ A$

No of electrons, $n=5\times 10^{13}$

We need to find how long will it take to given no of electrons to cross a certain cross section of the conductor.

Electric current,

$I=\dfrac{q}{t}$

t is time

Also, q = ne

$I=\dfrac{ne}{t}\\\\t=\dfrac{ne}{I}\\\\t=\dfrac{5\times 10^{13}\times 1.6\times 10^{-19}}{2\times 10^{-6}}\\\\t=4\ s$

So, it will take 4 seconds.

A crate of eggs is located in the middle of the flatbed of a pickup truck as the truck negotiates a curve in the flat road. The

oksian1 [2.3K]

Answer:

v = 14.35 m/s

Explanation:

As we know that crate is placed on rough bed

so here when pickup will take a turn around a circle then in that case the friction force on the crate will provide the necessary centripetal force on the crate

So here we have

$\mu mg = \frac{mv^2}{R}$

here we have

$\mu g = \frac{v^2}{R}$

now we know that

$v = \sqrt{\mu Rg}$

here we have

$\mu = 0.600$

R = 35 m

g = 9.81 m/s/s

now plug in all values in above equation

$v = \sqrt{(0.600)(35)(9.81)}$

$v = 14.35 m/s$

Use the passage to answer the question.

Studentka2010 [4]

This is not something that waves do because they need a medium to travel through, while particles do not.

<h3>How light travels in space?</h3>

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

So we can conclude that electromagnetic waves like light do not require medium for its propagation.
