Answer

The correct answer is "Plate A is negatively charged and plate B is positively charged"

Explanation:

In an electric field, the direction depends on the charge of the plate.

For a positively charged plate, the electric field is always directed away from it.

For the negatively charged plate, the electric field will be directed towards it.

Looking ate plate A, the electric field in directing toward it. Therefore, it's a negative charge.

For plate B, the electric field is moving away from it, making it a positively charged plate.

Answer:

$E_{net} = 6.44 \times 10^5 N/C$

Explanation:

As we know that electric field due to infinite line charge distribution at some distance from it is given as

$E = \frac{2k \lambda}{r}$

now we need to find the electric field at mid point of two wires

So here we need to add the field due to two wires as they are oppositely charged

Now we will have

$E_{net} = \frac{2k\lambda_1}{r} + \frac{2k\lambda_2}{r}$

now plug in all data

$\lambda_1 = 4.68 \muC/m$

$\lambda_2 = 2.48 \mu C/m$

$r = 0.200 m$

now we have

$E_{net} = \frac{2k}{r}(4.68 + 2.48)$

$E_{net} = \frac{2(9\times 10^9)}{0.200}(7.16 \times 10^{-6})$

$E_{net} = 6.44 \times 10^5 N/C$

Describe how sound waves are produced

Delvig [45]

Answer:

Sound waves are produced when something vibrates.

Explanation:

The vibrating body causes the medium (water, air, etc.) Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.

Sorry if this if wrong
