What's the formula for distance?

nekit [7.7K]

There are several formulas for distance. The one you choose to use is the one that expressed distance in terms of the information that you already have. For example, if you already know the speed and the time you've been traveling, then the formula for the distance you've covered is D = (speed) times (time) .

Consider an electron with charge âˆ’eâˆ’e and mass mmm orbiting in a circle around a hydrogen nucleus (a single proton) with cha

PtichkaEL [24]

Answer:

Explanation:

The net force on electron is electrostatic force between electron and proton in the nucleus .

Fc = $\frac{1}{4\pi\epsilon} \times \frac{e\times e}{r^2}$

This provides the centripetal force for the circular path of electron around the nucleus .

Centripetal force required = $\frac{m\times v^2}{r}$

$\frac{m\times v^2}{r}=\frac{1}{4\pi\epsilon} \times \frac{e\times e}{r^2}$

$v^2=\frac{e^2}{4\pi \epsilon m r}$

$v=(\frac{e^2}{4\pi \epsilon m r})^{\frac{1}{2} }$

Plz help asap for Edmentum/plato

lapo4ka [179]

Answer:

A. Gas atoms subjected to electricity emit bright lines of light

Explanation:

When subjected to electricity, the electrons of a gas atom are excited. From that excited energy level, the electrons eventually go back to their initial state; this transition is done by emitting photons at a specific wavelength (causing an emission of bright lines of light).

Such is the mechanism of gas-discharge lamps tipically found in households.
