How does the electrical force relate to the distance between two charged objects?

Answer

It is inversely proportional to the square of the distance

Explanation

This is the inverse square law , where in electrostatics, the electric force between two charged objects is inversely connected to the distance of separation between the two objects. This is to mean an increase in separation distance between objects will cause a decrease in the force of attraction between the objects.

<u>Answer:</u>

The correct answer option is 'It is inversely proportional to the square of the distance.'

<u>Explanation:</u>

The electrical force is inversely proportional to the square of the distance.

The relation of the electrical force to the distance between the two charged objects is given by the Coloumb's law which states that:

ef=k\frac{q_1*q_2}{r^2}

where ef is the electrical force, q_1 and q_2 are the two charges which are separated by the distance r.

Why is there an energy crisis if energy is supposedly conserved? Explain your answer and cite one example
faltersainse [42]

Answer:

Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. The energy that is wasted cannot be recovered.

The cost, C C, of producing x x Totally Cool Coolers is modeled by the equation C = 0.005 x 2 − 0.25 x + 12 C=0.005x2-0.25x+12 H
neonofarm [45]

Answer:

25 coolers are need to be produce and sell in order to minimize the cost.

Explanation:

C = 0.005x^2-0.25x+12 ..[1]

Differentiating the given expression with respect to dx.

\frac{dC}{dx}=\frac{d(0.005x^2-0.25x+12)}{dx}

\frac{dC}{dx}=0.01x-0.25+0

Putting ,\frac{dC}{dx}=0

0=0.01x-0.25+0

0.01x=0.25

x = 25

Taking second derivative of expression [1]

\frac{d^2C}{dx^2}=\frac{d(0.01x-0.25)}{dx}=0.01

\frac{d^2C}{dx^2}>0 (minima)

25 coolers are need to be produce and sell in order to minimize the cost.

What does redshift tell us about the object in the universe?(what is the relationship of the objects?) help me plsss
ki77a [65]

Answer:

Bottom line: A redshift reveals how an object in space (star/planet/galaxy) is moving compared to us. It lets astronomers measure a distance for the most distant (and therefore oldest) objects in our universe.

Explanation:

A redshift reveals how an object is moving in space and enables astronomers to discover otherwise-invisible planets and the movements of galaxies, and to uncover the beginnings of our universe.

They use a property called a "redshift" to describe the motion of an objects moving away from each other in space. Redshift occurs when an object emitting electromagnetic radiation recedes from an observer. The light detected appears "redder" than it should be because it is shifted toward the "red" end of the spectrum.Because the location of spectral features usually shifts to longer wavelengths -- towards the red end of the spectrum -- astronomers refer to this as the redshift of a galaxy. Take a look for yourself at the appearance of some very distant, very fast-moving galaxies in the Hubble Ultra-Deep Field .

hoped this helped a brainlist would be nice :)

**Narrowed it down please help!**
natka813 [3]

Answers:

1. B.)

2. Both A.) and B.)

3. A.)

Step-by-step explanation:

1. Ions in gas phase

A plasma is a gas consisting of electrons and positively charged ions.

Because the particles are ions and electrons, rather than neutral atoms or molecules as in ordinary gases, scientists consider a plasma to be a fourth state of matter<em>.</em>

2. Kinetic Molecular Theory

Both activities illustrate the postulate.

A.) If the particles are extremely small and far apart, most of the volume of a gas is empty space. That's why it's easy to push the plunger of a capped nozzle syringe containing a gas.

B.) If the particles are far apart, it's easy for a coloured gas to spread into an inverted jar placed on top of a jar containing the gas.

3. Hot air balloon

The high temperature in the balloon makes the gas molecules spread apart according to Charles's law, because this law describes how a gas will behave at constant pressure.

As the hot air escapes from the vent, the combined mass of balloon + hot air becomes less than the mass of cold air that it displaces, and the balloon rises.

B.) is <em>wrong</em>. Boyle's law applies only when both the number of moles and  the temperature remain constant.
