Answer: The heat flows into Earth's atmosphere which changes as the Sun rises and sets, which increases during the day.

Explanation:

Answer:

Object 1 and 3 are in motion.

Object 3 is in unbalanced form.

It is being snow rain and object 1 is sliding on water. Object 2 is in rest and object 3 is in motion blowing by air.

Object 1 and 3 are in motion , the unbalanced force is the force acting on object 3 and sledder is being acted upon by an external force.

Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.

Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.

Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic  mechanics is based on modern kinematics.

Answer:

When light hits a material, three different things can happen.

First, the material can absorb the energy.

Second, transmit the energy

Third, reflect the energy cause it to bounce off.

All these things can happen at once.

If the volume exiting the large intestine were 364 mL, then it would most likely indicate a case of diarrhea. This condition may lead to dehydration.

Diarrhea is an unhealthy condition that occurs when the body excretes an excessive amount of water.

Diarrhea must be treated because this condition can lead to dehydration (it may even lead to death in severe cases).

Both diarrhea and vomiting may lead to the loss of body fluids.

Answer:

Protons: 22

Neutrons: 26
Electrons: 22

Explanation:

Titanium's atomic number is 22, meaning that the number of protons it has in its nucleus is also 22. # of electrons = # of protons, so the number of electrons is also 22. Titanium has an atomic mass of 47.867, but we can round up to 48. To find the atomic mass, we add up number of protons and neutrons. We know the number of protons as 22, so we subtract 22 from 48 and get a number of 26. Thus, the number of neutrons is 26.

Answer: What should you do after finishing work with a reagent bottle? Return the bottle to its proper storage location. Close the bottle. Which steps are necessary for cleaning a spill involving broken glass?

After finishing work with a reagent bottle, you should close the bottle and return the bottle to its proper storage location. The correct options are A and C.

Reagent bottles are bottles used for storing powders and chemical liquids. They are made up of plastic, glass, or borosilicate. They are also UV or light protective, with a tint of red color in the glass.

Now, they are light protective because of some chemicals each with light and causing an explosion. They should be kept in dark bottles and in kept in cupboards.

Reagent bottles should be kept closed always after use. They should be handled carefully, as they contain chemicals. These bottles are used in chemistry labs and other labs in schools and big laboratories.

Thus, the correct options are A, Close the bottle, and C. Return the bottle to its proper storage location.

85.33 grams of hydrazine is needed for the reaction.

Rocket fuel contains the reaction between hydrazine and oxygen to break and form nitrogen and water vapour along with steam as it is an exothermic reaction.

The reaction can be shown as:

[tex]\rm N_{2}H_{4}(l) + O_{2}(g) \rightarrow N_{2}(g) + 2H_{2}O(g)[/tex]

From the periodic chart, it can be said that:

The molar mass of hydrazine will be:

[tex]\begin{aligned} \rm Molar \;mass \;of \rm \;N_{2}H_{4}&= 2(14) + 4(1) \\\\&= 32 \;\rm grams\end{aligned}[/tex]

Mass of water:

[tex]\begin{aligned}&= 2(1) + 16 \\\\&= 18 \;\rm grams\end{aligned}[/tex]

From the reaction, it can be said that,

1 mole of [tex]\rm N_{2}H_{4}[/tex] = 2 moles of [tex]\rm H_{2}O[/tex]

32 grams of [tex]\rm N_{2}H_{4}[/tex]  = ? grams of water

[tex]\begin{aligned}\text{Gram of water} &= 18 \times 2\\\\&= 36 \;\rm gm\end{aligned}[/tex]

So, for 96 gm of water the hydrazine produced will be,

[tex]\begin{aligned}\text{mass of }\rm N_{2}H_{4} &= \dfrac{96 \times 32}{36}\\\\&= 85.3334 \;\rm grams \end{aligned}[/tex]

Therefore, 85.33 grams of hydrazine is needed for the reaction.

Answer:

Demonstration 1 showed a chemical change because a new gaseous substance was formed, and demonstration 2 showed a physical change because liquid water became water vapor.

Explanation:

Chemical changes alter the chemical makeup of a subject, and a physical change only alters the appearance of a subject, not the chemical makeup.

Answer:

A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for the amount of a substance. There are, therefore, 6.02 × 10 23 water molecules in a mole of water molecules. Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen.

QUESTION ; WHAT IS POTENTIAL ENERGY?

ANSWER : LETTER "A"

EXPLANATION :

potential energy, stored energy that depends upon the relative position of various parts of a system. Potential energy is a property of a system and not of an individual body or particle; the system composed of Earth and the raised ball, for example, has more potential energy as the two are farther separated.
