Explanation:
In the formula Depth= V(T/2), why is the T (time) divided by 2?
The time taken is 2x the depth of the sea
Further explanationLinear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
An equation of constant velocity motion
[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]
x = distance = m
v = speed = m / s
t = time = seconds
The principle used in measuring depth is to use the reflection of sound waves emitted by the instrument towards the bottom of the sea. The sound will be reflected and received back by the instrument. So that the time taken is 2x the depth of the sea (emitted time + reflected time), so that the calculation of the depth distance must be divided by 2

What are two units that are used to measure volume in chemistry?
Answer:
The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.

Should the characteristics of life be redefined? Why and why not
Answer:
Ok audry vamos a esto,Si eso pasa,Los viruses dejaran de infectar o será peor? Si se redefina las características de la vida,Nos adaptarianos rapido?Que ganamos con cambiar eso? porque se debe de cambiar?
Ok audry let's get to this, if that happens, will the viruses stop infecting or will it be worse? If we redefine the characteristics of life, we adapt quickly? What do we gain by changing that? why should it be changed?
Explanation:
esas son las preguntas que tienes que hacer a ver si hace sentido el cambio que quieren hacer porque de que vale hacer un cambio sin saber si nos va a beneficiar o no O si eso va a resolver el conflicto. (is me lorenny XD )
Those are the questions that you have to ask to see if the change they want to make makes sense because of what is worth making a change without knowing if it will benefit us or not or if it will resolve the conflict. (is me lorenny XD)

Which of the following could be an appropriate citation for an article with 3 authors?
A. Jones, Davis, and Young, 2012
B. Davis, 2012
C. Jones, D and Y, 2012
D. Jones, et al., 2012
Answer:D
Explanation: if you have more than 2 authors , you cite the article by using the last name of the author followed by the phrase “et al”
APA- style citation is a writing format to mention and cite the sources in the journals and papers. Citation for an article with 3 authors is given as, Jones, et al., 2012. Thus, option D is correct.
What is APA- style citation?APA- style citation is the format given by the American Psychological Association. It is a citation style that quotes the author's last name and date. The data quoted are enclosed in parentheses. For example, (Robert, 1997)
Unlike MLA, the APA citation style capitalizes only the titles and proper nouns. The tiles in the source are written in italics. The in-text and the reference list of the citation differ a little.
When a source contains three authors then, the APA citation style writes the last name of the author followed by the et al., and the year like Jones, et al., 2012.
Therefore, option D. Jones, et al., 2012 is the correct APA citation style.

Lucas and Will are in an arm wrestling match. Lucas is pushing with a force of 55 Newtons. Will is pushing with a force of 62 Newtons. Who would win the arm wrestling match? Explain why. Use at least 3 complete sentences using vocabulary and examples from the lessons:
Answer:
This question is incomplete.
Explanation:
However, Will should win the match if other conditions are the same between the two of them. This is because Will is pushing with a higher force (of 62 Newtons). This is because the higher the force, the higher the workdone. The formula associated to the workdone here is
Workdone = Force × distance

What is dipole moment ?In a compound with atoms of significant difference in electronegativities, the shared pair of electrons attracts towards the more electronegative atom and this results in a charge separation. The measure of the separation of two electrical charges is called the dipole moment of the compound.
a. Fluorine is the most electronegative atom in periodic table. Compared to other halogens, F has very small atom and have less electron affinity compared to other halogens.
b. Cl - F is an interhalogen compound in which dipole moment is created by the electronegativity difference between Cl and F. The net dipole moment is towards the F atom.

Calculate the molality of a saline solution in which 50.0 g of NaCl is dissolved in 0.750 kg of water.
Answer: Molality of a saline solution = 1.14 moles per kg
Explanation:
Given mass of NaCl (m)= 50.0 g
Mass of solvent = 0.750 kg
Molar mass of NaCl (M)= 23 g + 35.5 g = 58.5g [Atomic mass of Na = 23 u , atomic mass of Cl = 35.5 u]
Number of moles (n) =[tex]\dfrac{m}{M}[/tex]
[tex]\dfrac{50}{58.5}=.8547[/tex]
Molality = [tex]\dfrac{\text{Number of moles }}{\text{Mass of solvent in kg}}[/tex]
[tex]=\dfrac{0.8547}{0.750}=1.1396\approx1.14\text{ moles per kg][/tex]
Hence, molality of a saline solution = 1.14 moles per kg

Answer:
Atoms are single neutral particles.
Molecules are neutral particles made of two or more atoms bonded together.
Answer:
a molecule is made up of atoms bonded together so while an atom is its own separate entity a molecule is what you get when those atoms bond together. these might be the same elements such as two oxygen Atoms bonded together (O2), or it might be different Atoms bonded together like water(H20)

Which of the following is the correct equation for calculating SPEED?
Answer:
Where is the following?
Explanation:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in meters (m) and time is in seconds (s), so the units will be in meters per second (m/s).
Answer:
Speed = Distance / Time
Explanation:
Distance = Speed * Time
Time = Distance / Speed
