Which statement belongs to daltons atomic theory

1 answer:

5 0

Atoms cannot be broken down into smaller pieces is the statement belongs to daltons atomic theory. Option B is correct.

The atom consists of matter that may be split without releasing electrical charges. It's also the smallest unit of matter with chemical element features.

The complete question is:

"Which statements belong to Dalton's atomic theory? Select all that apply.

A)Atoms cannot be created or destroyed.

B)Atoms cannot be broken down into smaller pieces.

C)All atoms of an element are identical.

D)Chemical reactions cause atoms to be rearranged."

According to Dalton's atomic hypothesis, atoms cannot be broken down into smaller bits.

Hence, option B is correct.

A capacitor is connected across an ac source. Suppose the frequency of the source is doubled. What happens to the capacitive rea

fgiga [73]

The capacitive reactance is reduced by a factor of 2.

<h3>Calculation:</h3>

We know the capacitive reactance is given as,

$Xc = \frac{1}{2\pi fC}$

where,

$Xc\\$ = capacitive reactance

f = frequency

C = capacitance

It is given that frequency is doubled, i.e.,

f' = 2f

To find,

$Xc$ =?

$Xc' = \frac{1}{2\pi f'C}$

$= \frac{1}{2\pi 2f C}$

$= \frac{1}{2} (\frac{1}{2\pi fC} )\\$

$Xc' = \frac{1}{2} Xc$

Therefore, the capacitive reactance is reduced by a factor of 2.

I understand the question you are looking for is this:
