a. Water vapor in the air
b. Water in the glass
c. Surrounding air
d. The glass
Answer:
D. The glass.
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it.

Calculate the mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2
Answer:
40kg
Explanation:
F=M*A
M=F\A
M=400\10
M=40kg
The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2 is 40 kg.
What is acceleration due to gravity?The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.
It is a vector quantity whose direction, strength, or magnitude match a plumb bob.
According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.
We know that,
F = m x g
m = f/g
Where,
F = force
m = mass
g = acceleration due to gravity
Given that,
F = 400N.
g = [tex]10m/s^2[/tex]
So,
m = 400/10
m = 40 kg.
Thus, the mass is 40 kg.

Write any three differences between mass and weight
please its aurgent fast
Answer:
See explanation
Explanation:
There are a number of differences between mass and weight, they include;
Mass is a scalar quantity whereas weight is a vector quantity.
Mass is dependent on the quantity of matter present in a body whereas weight depends on the acceleration due to gravity in a particular location on the earths surface.
The SI unit of mass is kilogram whereas the SI unit of weight is Newton.

Gravitational force multiple choice
Answer:
Option B. The force would be quartered (factor of 1/4).
Explanation:
The gravitational force between two objects can be expressed with the equation:
By analyzing the equation, we can see that if we multiply both m1 and m2 by 1/2, the resulting new F would be lower by a factor of 1/4 (as 1/2 times 1/2 equals 1/4).
Thus the correct answer is option B.
when an experiment shows that two variable are closely related the experiment shows what
Answer:When an experiment shows that two variables are closely related, the experiment shows correlation between the two variables. Correlation helps to show how two variables are related and connected. Related variables are said to be correlated. For example, we can say, good health is correlated to daily exercise routine.

Answer:The answer is the person and the tennis ball :)
Explanation:
Under certain external conditions, a person will perspire a great deal. For which internal condition does this response primarily provide homeostasis?
Answer:
Abnormally high temperature
Explanation:
Sweating or perspiration is a homeostatic response to abnormally high body temperature. Evaporation of the sweat causes cooling of the body and this causes the temperature of the body to return back to normal.
When the setpoint temperature of the body is breached by being too high, the negative feedback mechanism kicks-in, and the sweat glands of the skin becomes activated. The body sweats, and the evaporation of the sweat from the surface of the skin causes cooling and a return back to the setpoint.

Explain how an organ and organelles are related
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.
Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.
What is the relation between organ and organelles?Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.
Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.
Therefore, organ and organelles differ in their functioning.

it takes 25 min to cook 10 egg how long does it take to cook 20
Answer:
it takes 50 min
Explanation:
20 is twice of ten so if it take 25 min to cook ten then it is 50 min to cook 20.
Work for it:
10 x 2 = 20
10 eggs=10 min
25x2=50
Answer:
it takes 50 minutes to cook 20 eggs
Explanation:
ok first you have to see how long it takes 1 egg to cook so 25/10=2.5minute an egg then u multiply 2.5 x 20=50

Because A is dominant, that means your mother could carry a hidden O. If she does then when she gets pregnant, each child has a 50% chance of getting her dominant A and a 50% chance of getting her hidden, recessive O. If the child gets the O from mom and an O from dad, he or she will have an O blood type.

16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits
Answer:
C
Explanation:
The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.
There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.
A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.
Hence, the correct option is C.

if a sample known to be about 11,460 years old and has 400 carbon 14 Adams how many atoms are in the sample when organisms just died
Answer:
There are 1600 atoms when organism just died.
Explanation:
The statement is incorrect. The correct statement is:
If a sample known to be about 11,460 years old and has 400 carbon 14 atoms. How many atoms are in the sample when organisms just died?
The amount of atoms associated with radioactive isotopes decreases exponentially in time by means of the following formula:
[tex]n(t) = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial amount of atoms.
[tex]n(t)[/tex] - Current amount of atoms.
[tex]t[/tex] - Time, measured in years.
[tex]\tau[/tex] - Time constant, measured in years.
In addition, the time constant can be calculated in terms of the half-life of the radioactive isotope ([tex]t_{1/2}[/tex]), measured in years:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
If we know that [tex]t_{1/2} = 5,730\,yr[/tex], [tex]t = 11,460\,yr[/tex] and [tex]n(11,460\,yr) = 400[/tex], then the initial amount of atoms is:
[tex]n_{o} = \frac{n(t)}{e^{-\frac{t}{\tau} }}[/tex]
[tex]\tau = \frac{5,730\,yr}{\ln 2}[/tex]
[tex]\tau \approx 8,266.643\,yr[/tex]
[tex]n_{o} = \frac{400}{e^{-\frac{11,460\,yr}{8,266.643\,yr} }}[/tex]
[tex]n_{o} \approx 1600[/tex]
There are 1600 atoms when organism just died.
