''Particles have forces of attraction between them" PLEASE HELP ME WRITE A SHORT PARAGRAPH ABOUT THIS

Chemistry
1 answer:
Tom [10]4 years ago

If you are talking about atoms and molecules, Heres what I would write. 

Particles have an attraction between each other because two objects of the same mass <span>will share a center of gravity that is exactly the midpoint between the two objects, so this means that neither of the particles will have more attraction then each other. So this also means that they would orbit each other. A</span><span>n orbit is a way of "circular falling."

I hope that this helps! </span>

Some fireplace logs (commercially made) burn with a red and/or green flame. Using the information in this experiment, what eleme
Diano4ka-milaya [45]

Answer:

Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium, and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame. When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colors. Each metal gives a characteristic flame emission spectrum

If Maria winks exactly 5 times every minute and she sleeps
Elina [12.6K]

First, we need to find the amount of winks in an hour, to simplify it so we can answer easier. Since there are 60 minutes in an hour, we can multiply 5 by 60 to find the number of winks in an hour.

5*60=300

Now multiply 300 by 8.

300*8=2,400

She winks exactly 2,400 times per day.

Hope this helps!

The density of iron is 7.8 g/cm^3 (cubed), what is the mass of 5 cm^3 (cubed) of it? Include the symbol for the correct unit.
Monica [59]

Answer:

<h2>The answer is 39 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of iron = 5 cm³

density = 7.8 g/cm³

It's mass is

mass = 5 × 7.8

We have the final answer as

<h3>39 g</h3>

Hope this helps you
