On a number​ line, suppose the coordinate of A is​ 0, and ARequals5. What are the possible coordinates of the midpoint of AR overbar​? The possible coordinates for midpoints of the segment are nothing. ​(Type integers or decimals. Use a comma to separate answers as​ needed.)

Time taken is given by :

[tex]t=-\dfrac{1}{k}\dfrac{[A_t]}{[A_o]}[/tex]    .......( 1 )

Also,

[tex]k = \dfrac{0.693}{t_{0.5}}\\\\\\k=\dfrac{0.693}{0.5}\\\\k=2\times 0.693\ year^{-1}[/tex]

Putting value of k in equation 1, we get :

[tex]t=\dfrac{1}{2\times 0.693}\times ln(\dfrac{2}{16})\\\\t=1.5\ years[/tex]

Therefore, time taken is 1.5 years.

Hence, this is the required solution.

The functional unit is called a system.

The stomach, small intestine, and large intestine are all organs. When they work together to process food, they form a functional unit known as a system. The correct option is b.

The living body performs many functions. These functions are performed by different systems of the body. There are many systems in the body.

These systems are digestive systems, reproductive systems, circulatory systems, etc. These systems run the body and make an organism.

Here, the stomach, small intestine, and large intestine are all organs of the digestive system. Digestive system digest the food that we eat and provides us energy and removes the waste material from the excretory system, which excretes it out of the body.

Thus, the correct option is b. system.

Explanation:

Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars. It is also called "hydrogen burning", which should not be confused with the chemical combustion of hydrogen in an oxidizing atmosphere.

Answer:

The number of protons plus the number of neutrons

Explanation:

Answer:

The mass number is equal to the total number of protons and neutrons in the nucleus of an atom.

Explanation:

Answer: Water and oil cannot mix

Explanation:

According to the speed formula, distance that Tony ran at  a constant speed of 10 m/s for a total of 60 seconds is 600 meters.

The speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity.

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.

Yes, just not a fixed shape.

Explanation:

A liquid take shape of whatever is containing but that does not fix it. As long as it is being contained it retains it's shape, yet the second you release it from it's containment it becomes the shape and can take the physical properies of whatever it is contained by next.

Answer:

1. documenting, tinkering, testing

Explanation:

Technological design is defined as the process of study, design and development of new technologies.

There are some action in the methodical tests and refinements specific to technological design include documenting, tinkering, testing.

Documenting includes collecting all the information about the design and develop the product, tinkering involves repairing or adjust the issues found in the development, and testing helps to evaluate if the product is ready to work as it is supposed to.

Hence, the correct answer is "1."

From the question

mass of stone = 24.595 g

volume = 5.34 cm³

The density of the stone is

[tex]density = \frac{24.595}{5.34} \\ = 4.605805243...[/tex]

We have the final answer as

Answer:

218.09g

Explanation:

the formula for density is mass/volume

you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3

so mass equals density x volume

and 19.3 x 11.3 = 218.09

Explanation:

Answer:

A. is not

B.  incorrect

C. identify substances that have the measured molecular mass

Explanation:

Since in the question it is mentioned that the Christy who is a forensic scientist and she gave a white powder and identify whether it is a sugar or not when she tested she seen that the molecular mass is different as compared with the sugar

So here it can be concluded that the white powder does not show a sugar that means it is not a sugar so automatically the hypothesis of Christy is wrong. And, the next step is to track the substance that shows the molecular mass i.e. measured

Answer:

- is not

-incorrect

- identify substances that have the measured molecular mass

Responda:

+ 0,9kJ / mol

Explicação:

Dados os calores de combustão do enxofre monoclínico e enxofre rômbico como - 297,2 kJ / mol e - 296,8 kJ / mol, respectivamente para a variação na transformação de 1 mol de enxofre rômbico em enxofre monoclínico conforme mostrado pela equação;

S (mon.) + O2 (g) -> SO2 (g)

Uma vez que são todos 1 mol cada, a mudança na entalpia será expressa como ∆H = ∆H2-∆H1

Dado ∆H2 = -296,8kJ / mol

∆H1 = -297,2kJ / mol

∆H = -296,8 - (- 297,2)

∆H = -296,8 + 297,2

∆H = 297,2-296,8

∆H = + 0,9kJ / mol

Portanto, a mudança na entalpia da equação é + 0,9kJ / mol
