Answer:
C. As speed increases, kinetic energy increase exponentially
Explanation:
As you can see on the graph, the further right we move on the x-axis, the higher the values on the y-axis. This means that as one value increases, the other value also increases. The only answer choice that says this is C.
Hope this helps :)
is C because i did it on the quiz

Scientists digging in a cave found an unknown substance. The scientists
found that the substance’s molecules were moving around each other. The scientists
increased the speed of the substance’s molecules and caused a phase change. How
did the scientists do this, and how did this affect the substance?
Answers
Answer:
By adding heat energy
It became a gas
Explanation:
The molecules moving about another is a clear indicator that the substance is a liquid.
In a liquid, the molecules stick together and move about one another.
When the scientist increase the speed of the of substance, the kinetic energy increases. if this increase causes a phase change, then the substance becomes a gas. So, by adding heat energy a substance becomes gaseous if it is a liquid already.HELLLLPPPPPPP

The diagram below shows a longitudinal wave at one instant in its motion. Each oval represents a particle acted on by the energy of the wave as it moves from left to right.
Which line on the diagram indicates a region of rarefaction?
Answers
Answer:
Here now you can give the other person the brainly they deserve and they were right too :)
Explanation:
The line that has been the representation of the region of rarefaction in the diagram has been the line below the top line.
The diagram has been the representation of the movement of the particles under the influence of wave energy. The particles have been moving from left to right in the longitudinal order with a gain of energy.
The rarefaction has been the instance where the density of the waves has been lesser or where there has been one wavelength of the wave.
The diagram has been representing, at the line below the top arrow, there have been lesser density of the wave particles, thus, the region of rarefaction has been the instance in the lines below the top line.

HELP ME PLEASE!! If given a graduated cylinder, a beaker with alcohol and a scale, explain the steps to find the mass of 40 mL of alcohol.
Answers
In general, some people equate mass and weight.
Mass is one of the principal quantities, which is related to the matter , whereas weight is a force that leads to the center of the earth (Earth's gravitational force)
Steps that can be taken to find the mass :
1. Weigh graduated cylinder (empty) 2. Pour the alcohol in the beaker into the graduated cylinder to the level of 40 ml 3. Weigh again graduated cylinder + poured alcohol 4. mass of alcohol 40 ml = mass in 3rd step - mass in the first stepA substance has a molecular formula of C8H10N4O2

Which of the following is an extensive property of a sample of aluminum?
Answers
Answer:
Entropy,mass and volume.... I think
Mass is the extensive property of a sample of aluminum. Therefore, option (A) is correct.
What is the extensive property of matter?The extensive property can be described as a physical property of matter that changes with a change in the size and shape of the matter. Therefore, the extensive property of any substance varies directly with the mass.
Extensive properties are the value of the property of the system that must be equal to the sum of the values of different parts of the system. These properties depend on the amount of matter contained in the system.
Examples of Extensive properties are temperature, pressure, density, boiling point, etc. The ratio of the two extensive properties is an intensive property such as density.
The mass of a sample of aluminum is an example of extensive property as it depends on the amount of aluminum in the given sample. This property of the sample is proportional to the size of the system.

In what way do the atoms in the same row of the Periodic Table increase from left to right?
Answers
Answer:
As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.

how can you find the Frequency if you only have the wavelength? can you solve this example what is the Frequency of the wavelength 4km? can you please show your steps thanks.
Answers
Answer:
75000 Hz
Explanation:
f = V / λ (f= frequency, v=velocity of wave, lambda= wavelength)
alternatively, f = c / λ (f= frequency, c= speed of light- 3.00x10^8 m/s, lambda= wavelength)
f= [3.00x10^8 m/s]/[4000 m]
=75000 Hz
