Identify the type of wave that would be located at Point A below.​

Answer:

It has direction and size.

Explanation:

The way I learned it was that vectors have direction and Magnitude. Magnitude is just the length of the vector. So you are right.

Answer: Nerves, Brain and spinal cord

Explanation:the other choices are either part of the cardiovascular system or the respiratory system

Hello Mistyann!

First you need to know amount of barium phosphate is

Half of potassium phosphate, also 2.18 mol.

Molar mass of Barium phosphate is 3·137.2 + 2·(30.97+4·16) g/mol

You can calculate it yourself dear.

Now mass is amount of substance · molar mass.

It has been an honour to teach you, dear,

God bless!

Explanation:

we just did this in class last week haha i know my math :)

Answer:

I think it is either a or b

Explanation:

c or d has the correct names and Roman numerals.

Answer:

conductors of electricity when in liquid or aqueous state

high melting point

soluble in water

Explanation:

An ionic substance is any substance that is composed of two ions of opposite charge.

In the solid state, ionic substances do not conduct electricity because the ions are trapped inside the crystal. When in liquid state or in aqueous solution, these ions are now free and the solution becomes an electrolyte.

All ionic substances have a very high melting point and dissolve in water easily.

Answer:

Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop

Answer:

Mountains effect them with contact

Explanation:

They are always pushing eachother and crash

Answer:

There is a ozone layer because of the special atomphere and chemical conditions that takes place there. I think the consequences of that home area is the very low winter temperatures.

Answer:

There is a hole in the ozone layer because of the pollution on earth. Because of that the UV rays are easily entering the earth through that portion. The consequences of this can be cancers, global warming and disastrous storms.

Answer:

[tex]V_2=1.34L[/tex]

Explanation:

Hello there!

In this case, since this problem is describing how pressure changes as a function of volume and vice versa, it is possible recall the Boyle's law as shown below:

[tex]P_1V_1=P_2V_2[/tex]

Whereas we are asked to compute the volume when the change is pressure is performed (V₂); thus, we proceed as follows:

[tex]V_2=\frac{P_1V_1}{P_2}\\\\V_2=\frac{1.55L*105.2kPa}{122.0kPa}\\\\V_2=1.34L[/tex]

Best regards!

Answer:

due to the law of conservation of mass, the mass would stay the same.

Answer:

200 N to the west b/c we have 1500 to west and

1300 N to east . the forces have a opposite direction.

thus we add the force. and we gain 200N force.

Explanation:

C9H2O + 14O2 → 9CO2 + 10H2O

a. How many molecules of nonane will burn in a tank that has 770 mL of oxygen at STP?

From the reaction;

1 mol of nonane reacts with 14 mol of Oxygen

At STP, 1 mol = 22.4 L

Converting 770 ml (0.77 L) to mol;

1 = 22.4

x = 0.77

x = 0.77 / 22.4 = 0.034375 mol

Back to the equation;

1 mol = 14 mol

x mol = 0.034375 mol

Solving for x;

x = 0.034375 * 1 / 14

x = 0.00245535714 mol

1 mol = 6.022 * 10^23 molecules

0.00245535714 mol = x

Solving for x;

x = 0.00245535714 * 6.022 * 10^23

x = 1.4786 * 10^21 molecules

b. If the container were heated to 78O C before the combustion, what would the pressure be?

Initial Pressure P1 = ?

Initial Temperature T1 = 780 +273 = 1053 K

Final Temperature (STP) T2 = 273 K

Final Pressure (STP) P2 = 1 atm

Using gay lusaac's law;

P1 / T1  =  P2 / T2

Inserting the values;

P1 = T1 * P2 / T2

P1 = 1053 * 1 / 273

P1 = 3.857 atm

Answer:

endothermic

Explanation:

Weathering is the physical and chemical breakdown of rock at the earth's surface. ... The physical breakdown of rock involves breaking rock down into smaller pieces through mechanical weathering processes. These processes include abrasion, frost wedging, pressure release (unloading), and organic activity.
