A parallel-plate capacitor is disconnected from a battery, and the plates are pulled a small distance farther apart. Does Q incr

kolezko [41]

Answer:

Q stay the same

Explanation:

Charging of capacitor is done by battery . If battery is disconnected , charging will stop . There will not be any discharging as plates are separate . So pulling the plates apart will not affect the charge lying on the capacitor . It will decrease its capacity and increase its potential , keeping its charge constant.

The change in velocity during a measurable time interval, divided by the time interval, is the _____.

scoray [572]

Hello!

Let's put it into symbols:

Change in velocity = $\mathsf{V_f - V_i=\Delta V}$
A measurable interval: $\mathsf{\Delta t}$

This division is:

$\mathsf{\dfrac{\Delta V}{\Delta t}}$

We can recognize this as the Average Acceleration $\mathsf{a_m}$

Given two positively charged particles, of equal magnitude, separated by a distance “d”. What will happen to the force field bet

Ulleksa [173]

The force between the two particles will quadruple

Explanation:

The magnitude of the electrostatic force between two charges is given by Coulomb's law:

$F=k\frac{q_1 q_2}{d^2}$

where:

$k=8.99\cdot 10^9 Nm^{-2}C^{-2}$ is the Coulomb's constant

$q_1, q_2$ are the two charges

d is the separation between the two charges

In this problem, let's call F the initial force between the two charges, when they are at a distance of d.

Later, the distance between the two particles is halved, so the new distance is:

$d'=\frac{d}{2}$

This means that the new electrostatic force will be:

$F'=k\frac{q_1 q_2}{(d/2)^2}=4(k\frac{q_1 q_2}{d^2})=4F$

Therefore, the force between the two particles will quadruple.
