krok68 [10]

Answer:

it is essential that the charge on the plates are of the same magnitude, but in the opposite direction

Explanation:

The configuration of parallel plates is called a capacitor and is widely used to create constant electric fields inside.

To obtain this field it is essential that the charge on the plates are of the same magnitude, but in the opposite direction

This is so that the fields created by each plate can be added inside and subtracted from the outside of the plates

Rama09 [41]

Answer:

(a). The change in the average kinetic energy per atom is $1.57\times10^{-21}\ eV$ .

(b). The change in vertical position is 2413 m.

Explanation:

Given that,

Mass = 40.0 u

The increased temperature from 286 K to 362 K.

(a). We need to calculate the change in the average kinetic energy per atom

Using formula of kinetic energy

$\Delta K.E=\dfrac{3}{2}k\Delta t$

Put the value into the formula

$\Delta K.E=\dfrac{3}{2}\times1.38\times10^{-23}\times(362-286)$

$\Delta K.E=1.57\times10^{-21}\ eV$

(b). The change in potential energy of the container due to change in the vertical position

We need to calculate the change in vertical position

Using formula of potential energy

$\Delta U=mg\Delta h$

$\Delta h =\dfrac{\Delta U}{mg}$

$\Delta h=\dfrac{1.57\times10^{-21}}{40.0\times1.66\times10^{-27}\times9.8}$

$\Delta h=2412.7=2413\ m$

Hence, (a). The change in the average kinetic energy per atom is $1.57\times10^{-21}\ eV$ .

(b). The change in vertical position is 2413 m.
