Answer:

To say that an object is electrically polarized is to say that object have polarity and the charges on both the poles are not equal in either magnitude or direction.

Explanation:

When an object is subjected to any external electric field, the electric field distorts the negatively charged electrons into opposite direction of the field and polarization occurs.

<h3>Ⲋⲟⳑⳙⲧⳕⲟⲛ :</h3>

We are given that a cylinder shaped bucket is used as a sand container . We have to find how much sand it can hold , which can be found by knowing the volume of cylindrical bucket .The volume of a cylinder is given by :

$\quad\dashrightarrow\quad {\pmb{\sf {Volume = \pi r^2 h }}}$

where,

π = 3.14
r = 0.5 feet
h = 2.5 feet

$\quad\dashrightarrow\quad \sf {V =\pi r^2 h }$

$\quad\dashrightarrow\quad \sf { V = 3.14 \times 0.5^2 \times 2.5}$

$\quad\dashrightarrow\quad \sf {V = 3.14\times 0.5\times 0.5\times 2.5 }$

$\quad\dashrightarrow\quad \sf {V = 1.9625 }$

‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ~Hence, the bucket can hold 1.96 feet³ of sand!

How many electrons pass through a 20-ohms resistor in 10 min if there is a potential drop of 30 volts across it?

tangare [24]

The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.

<h3>What is a resistor?</h3>

In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.

Given, the resistance is 20 ohms.

The potential difference is 30 volts

Time is 10 minute

By the formula of current

$\rm I = \dfrac{30}{20} = 1.5 \;C/s$

The charge flowing through the resistor is 1.5 C/s

1 electron charge is 1.6e+19

Now, the number of electrons passing through a 20 ohms resistor is

$\dfrac{1.5}{1.6e+ ^2^1} = 0.9375e+^1^9$

In 10 minutes

$0.9375e+^1^9 \times 60 \times 10 = 5.625e+^2^1$

Thus, the number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
