Answer: water vapor
Explanstion
When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. ... Those drops of water are called condensation
The steam coming off the pot of boiling water is an example of Water vapor.
Water Vapor
Water throughout a gaseous condition, particularly in the atmosphere and at temperatures lower than the boiling point. This same basic ingredient for cloud as well as rain production is water vapor throughout the environment.
It also serves to maintain the Earth's temperature by reflecting and dispersing solar energy as well as absorbing infrared heat from this same Planet.
Thus the response above is correct.

What distance could a toddler travel if they crawl at a rate of .73 m/s for 20 seconds?
Answer:
14.6 m (meters)
Explanation:
When working with time, and speed.
Use d = st, since s = d/t (just rearanging the formula for speed). d is for distance, t is for time, and s is for speed (velocity with no direction).
To solve for the distance just multiply the rate of speed by the time to get distance.
Given .73m/s is the speed, and 20s is the time.
d = st
d = .73 m/s × 20s
d = .73m × 20
d = 14.6 m
How are both chemistry and physics related to geoscience?
Answer:
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical and chemical constitution of the Earth and its atmosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields.
There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events.
The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth's interior, as well as the atmosphere, hydrosphere, and biosphere. Typically, Earth scientists use tools from geology, chronology, physics, chemistry, geography, biology, and mathematics to build a quantitative understanding of how the Earth works and evolves. Earth science affects our everyday lives. For example, meteorologists study the weather and watch for dangerous storms. Hydrologists study water and warn of floods. Seismologists study earthquakes and try to understand where they will strike. Geologists study rocks and help to locate useful minerals. Earth scientists often work in the field—perhaps climbing mountains, exploring the seabed, crawling through caves, or wading in swamps. They measure and collect samples (such as rocks or river water), then they record their findings on charts and maps.

Jaime knew that altitude influenced the climate because he lived in the Rocky Mountains at a high altitude. Altitude is a more important factor in climate than latitude in mountainous areas. What relationship exists between altitude and other climate factors? A. An increase in altitude results in higher levels of precipitation. B. An increase in altitude results in an increase in air pressure. C. An increase in altitude results in a decrease in temperature. D. An increase in altitude results in a lessening of wind speed
Answer:
C. An increase in altitude results in a decrease in temperature.
Explanation:
The climate of an area is highly influenced by its altitude especially in mountain areas.
At higher altitudes or mountains, the air molecules above a given surface are fewer that decreases the air pressure in the area and decreases the temperature of the area as well. Because of fewer air molecules, gases absorb very little of the incoming solar radiation and cause decrease in temperature.
Hence, the correct answer is "C. An increase in altitude results in a decrease in temperature."

Answer:
7.5s1.6666 repeating or 1.67 m/s²Explanation:
the equation you have to use is Vfinal=Vstart+acceleration•time(I'm gonna simplify to Vf=Vs+at)
so you gotta rework it for the two equationsfor the first equation you need time so take Vf=Vs+at and subtract Vs on both sides to get Vf–Vs=atthen divide acceleration on both sides to get t=(Vf–Vs)/afor the second problem equation need the equation a=(Vf–Vs)/t (just divide time on both sides instead of acceleration)so you the plug in(I don't put the units in to the problem unless needed)
1. t=(Vf–Vs)/a to t=(0–30)/-4.0
t= -30/-4.0t=7.5 seconds2. a=(Vf–Vs)/t to a=(10–0)/6.0
a= 10/6.0a= 1.67m/s²(I'm assuming the that for number two they started at rest so it would be 0m/s for velocity start)

Does research lessen its value for its being cyclical? Enumerate Two Possible advantages of a cyclical research
Answer:
Research usually is a cyclical process because it starts with a problem and ends with a problem.
This is bad or lessens the value of the research?
No, because there are problems that in nature are cyclical, (for example the related ones to action research).
And it also may be a good thing, solving one "problem" leads to another problem, but in the process of solving the first one we may win a lot of knowledge, and the same happens with the next one, and so on.
Two possible advantages of cyclical research are:
Knowing beforehand that the research will be cyclical, will allow us to estimate better the amount of time and money needed because we already know (more or less) where to aim.
It also may lead to a better end product, as we already know that we must focus in solving one thing and then we can focus in the next one.
Another possible advantage may be that we know that after the work, there will be a new thing to research, and it is fun, so if you are curious enough this may be a good thing (especially in scientific areas, physics, chemistry, etc).

Which of the following graphs best shows the velocity v of the clay ball from when it is dropped until it hits the ground?
Answer:
The correct option is;
C
Explanation:
The given information is that a clay ball is dropped from a certain height.
Therefore, the clay ball has an initial potential energy and zero kinetic energy
Which gives that the initial velocity of the clay ball = 0
As the potential energy is converted into kinetic energy, the velocity of the clay ball increases
However, if the direction of measurement of the velocity is opposite to the direction in which the clay ball is falling, the velocity of the ball progressively increases negatively as shown in option C
laws of solid friction
Answer: When an object is moving, the friction is proportional and perpendicular to the normal force (N)
Friction is independent of the area of contact so long as there is an area of contact.
The coefficient of static friction is slightly greater than the coefficient of kinetic friction.
Within rather large limits, kinetic friction is independent of velocity.
Friction depends upon the nature of the surfaces in contact.
Explain conservation of charges and find final charges on each square plate (first one has side 1 cm and -5 charge the second one has side 2 cm and +15 charge) when they are touched each other.
help (;´༎ຶٹ༎ຶ`)
Answer:
The final charge on each square plate is +10
Explanation:
The law of conservation of charge states that the charge in a system, isolated from the environment, can only be transferred to another system, as the charges can neither be destroyed nor created
Therefore, the sum of the charges in a system is always constant such that the net charge in the universe is constant
Therefore, given the amount of charges in the 1 cm side = -5
The amount of charge in the 2 cm side = +15
The net charge when they touch = The charge on the 1 cm + The charge on the 2 cm
The net charge when they touch = -5 + 15 = +10
The final charge on each square plate = +10.
A ball is projected horizontally from the top of a building. One second later, another ball is projected horizontally from the same point, with the same velocity. Will the first ball always be travelling faster than the second one?
The speed of the balls will be same but the time to reach ground will be different.
Final velocity of the ballsThe final velocity of each of the balls will be determined by applying the first kinematic equation as shown below;
Vf = Vi + gt
where;
Vf is the final velocity of the ballsVi is the initial velocity of the ballsg is acceleration due to gravityt is time of motion of the ballFinal velocity of the first ballVf = Vi + 9.8t₁
Final velocity of the second ballVf = Vi + 9.8t₂

A rock is thrown upward with a vertical speed of 35 m/s and a horizontal speed of 12 m/s on
level ground. How far away does it land?
Answer:
R = 85.73 m
Explanation:
It is given that,
The vertical speed of a rock, [tex]v_y=35\ m/s[/tex]
The horizontal speed of a rock, [tex]v_x=12\ m/s[/tex]
We know that,
The vertical speed,
[tex]v_y=v\sin\theta=35\ ....(1)[/tex]
Horizontal speed,
[tex]v_x=v\cos\theta=12\ ....(2)[/tex]
Dividing equation (1) by (2) such that,
[tex]\dfrac{v_y}{v_x}=\dfrac{v\sin\theta}{v\cos\theta}\\\\\dfrac{35}{12}=\tan \theta\\\\\theta=\tan^{-1}(\dfrac{35}{12})\\\\\theta=71.07^{\circ}[/tex]
Let v is the initial velocity of the projection. So,
[tex]v=\sqrt{v_x^2+v_y^2} \\\\v=\sqrt{12^2+35^2} \\\\v=37\ m/s[/tex]
We need to find the distance where it will land i.e. the range of the projectile. It is given by the formula as follows :
[tex]R=\dfrac{v^2\sin2\theta}{g}\\\\\text{Putting all the values, we get }\\\\R=\dfrac{37^2\times \sin(2\times 71.07)}{9.8}\\\\R=85.73\ m[/tex]
So, it will land at a distance of 85.73 m.
