Measure the width of a sheet of a standard-sized (8.5in x 11.0in) loose-leaf notebook paper. Make the measurement in centimeters

laiz [17]

Answer: width = 27.94 cm

Explanation:

Given a sheet of a standard-sized (8.5in x 11.0in) loose-leaf notebook paper.

From the value given, the width is 11.0 inches

To make the measurement in centimeters, we will convert inches into centimeters.

1 inche = 2.54 centimeters

That is, 11 × 2.54 centimeters = 27.94 cm.

Therefore, the width is 27.94 cm.

A parallel-plate capacitor has plates of area A. The plates are initially separated by a distance d, but this distance can be va

ohaa [14]

Answer:

d' = d /2

Explanation:

Given that

Distance = d

Voltage =V

We know that energy in capacitor given as

$U=\dfrac{1}{2}CV^2$

$C=\dfrac{\varepsilon _oA}{d}$

$U=\dfrac{1}{2}\times \dfrac{\varepsilon _oA}{d}\times V^2$

If energy become double U' = 2 U then d'

$U'=\dfrac{1}{2}\times \dfrac{\varepsilon _oA}{d'}\times V^2$

$2U=\dfrac{1}{2}\times \dfrac{\varepsilon _oA}{d'}\times V^2$

$2\times \dfrac{1}{2}\times \dfrac{\varepsilon _oA}{d}\times V^2=\dfrac{1}{2}\times \dfrac{\varepsilon _oA}{d'}\times V^2$

2 d ' = d

d' = d /2

So the distance between plates will be half on initial distance.
