As the number of significant figures increases, the more accurate or precise the measurement is.

<h3>What is significant figure?</h3>

The term significant figures refers to the number of important single digits in the coefficient of an expression in scientific notation.

Significant figures are the digits in a value that are known with some degree of confidence.

The effect of reporting more or fewer figures or digits than are significant;

As the number of significant figures increases, the more accurate or precise the measurement is.

As precision of a measurement increases, so does the number of significant figures.

1)A plastic rod is rubbed against a wool shirt, thereby acquiring a charge of -0.7 µC. How many electrons are transferred from t

ratelena [41]

Answer:

electrons are transferred from the wool shirt to the plastic rod is 4.375 × $10^{12}$ electrons

Explanation:

given data

Amount of charge transferred Q = -0.7 μC = -0.7 × $10^{-6}$ C

electrons of charge e = -1.6 × $10^{-19}$ C

solution

we apply formula here for total charge of electrons that is

Q = n × e ...................2

here n is no of electron that is

n = $\frac{Q}{e}$

put here value

n = $\frac{-0.7*10^{-6}}{-1.6*10^{-19}}$

n = 4.375 × $10^{12}$ electrons

so here electrons are transferred from the wool shirt to the plastic rod is 4.375 × $10^{12}$ electrons
