how do convection currents form ?

Answers

Answer:

Convection currents occur when a fluid is near a heat source.

Explanation:

Heat sources provide energy to their surroundings. When fluid receives this energy, molecules inside it move around more, spacing out from each other and lowering the density.

We know from helium balloons that things with lower densities than their surroundings are pushed upwards. Therefore, the fluid close to the heat source moves upwards, as it is hotter than the rest.

As this fluid moves up, cooler molecules drift down, succumbing to gravity.

As hot molecules move up and further from the heat source, they cool down, and drop. As colder molecules drop and move towards the heat source, they heat up, and begin rising.

This results in a circular motion called a convection current. It is present in the strong winds at the seaside and in the magma in the Earth's mantle.


What is the relationship between a white dwarf and black dwarf?

Answers

Answer:

No longer emitting heat or light, the white dwarf will become a black dwarf. Because it emits no radiation, it is nearly impossible to see. However, the black dwarf would still retain its mass, allowing scientists to detect the effects produced by its gravitational field.

Explanation:

Answer:

white dwarfs are hot, black dwarfs are cold

Explanation:

a white dwarf is a slowly burning and aging corpse of a main sequence star such as our sun. they are up to 40 times hotter then the sun, ranking among one of the hottest objects in the universe, except their luminosity is so low that all their heat stays in them basically forever.

On the other hand, a black dwarf is a theoretical ending to a white dwarf, over the course of trillions of years, white dwarfs cool down into black dwarfs. black dwarfs rank among the coldest possible temperature. We aren't sure if these are really a thing, because we still haven't given white dwarfs enough time to cool down.

Use the information below to explain why the atomic radius decreases across a period.

Answers

Answer:

Detail is given below.

Explanation:

Atomic radius  trend along period:

As we move from left to right across the periodic table the number of valance electrons increases. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.

we can see in picture A there is one positive charge and force of attraction is 2.30×10⁻⁸ N

In picture D there are 2 positive charge and force of attraction is 4.60×10⁻⁸ N

So by increasing the positive charge force of attraction also increases.

In F we can see there is more positive charge thus force of attraction is also greater.

The half life of iodine-125 is 60 days. What was the initial amount of iodine-125 if you have 4.5 grams after 360 days?

Answers

Answer:

288 grams

Explanation:

The amount of any radiative substance left after some time is calculated by

amount left = [tex]x/2^n[/tex]

where x is the initial amount of substance

n is the number of half lives

one half live is the time in which amount of substance reduce to half of its initial value.

------------------------------------------------------

amount left = 4.5 grams

half life of  iodine-125 = 60 days

total time in which substance reduced to 4.5 grams  = 360 days

thus,

number of half life in 60 days = 360/60 = 6

thus, there are period of 6 half lives

in each half life the amount of substance reduces to its previous half

let the initial amount be x grams

using the formula

amount left = [tex]x/2^n[/tex]

[tex]4.5 = x/2^6 \\ 4.5 = x/64\\x = 4.5*64 = 288[/tex]

Thus, 288 grams was the initial amount of iodine-125

Answers

the volume is 1,409,725 meters

goes into a calculator and comes out w the given answer

If a large office building is 1.07 x 10^2 meters long, 31 meters wide. and 4.25 x 10^2 meters high, then the volume of the building would be 1409725 meters cube.

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

As given in the problem we have to calculate the volume of a large office building having the dimensions of  1.07 x 10 ^2 meters long,  31 meters wide, and 4.25 x 10^2 meters high.

The volume of the office building = length × width × height

                                                        =107 × 31 × 425

                                                        =140925 meters cube

Thus, the volume of the building would be 140925 meters cube.

What is meant by the statement "Atoms are electrically neutral"?

Answers

Answer:

They have the same number of electrons as protons.

Explanation:

Atoms are electrically neutral means that all the charges within the atom are balance to equal neutral. An atom has the same number of protons as it does electrons, therefore the charge is neutral.

An ion has a different number of electrons than protons, making the ion either positively or negatively charged.

Answer:

Hi! I am currently taking AP Chemistry, I'll try to help you out.

That quote basically just means that the atom as a whole is not positively or negatively charged. Atoms are made up of protons, neutrons, and electrons. Neutrons are neutrally charged. Protons are positively electrically charged. And electrons are negatively electrically charged. In atoms, if there is an even number of protons and electrons, they can cancel each other's charges out, which results in the atom as a whole being electrically neutral.

What is heart?

Heart is a muscular organ which is present in most of the animals , it is responsible for pumping blood via the blood vessels to the entire body.The blood which is pumped carries oxygen and nutrients along with it.Along with it on it's way back to heart it carries carbon dioxide to the lungs.

Heart has an approximate size of a closed fist and is present between the lungs in the middle compartment of the chest. It is divided in to for chambers , the upper chambers called atria and lower ones called ventricles.

The wall of the heart is made up of three layers : epicardium,myocardium and endocardium. It pumps blood with a rhythm which is determined by a group of cells which are called the pacemaker cells present in the sinoatrial node.
