The one that has the most thermal energy out of the following is 1 gallon of boiling water.
Thermal energy is the energy generated by a material as a result of particle movement inside the material. Thermal energy causes things to have an internal temperature, which may be measured. The greater the temperature measured, the quicker the particles travel within the system.
The full-size candy bar that is melting melts at a slower particle rate compared to the 1 gallon of boiling water whose particles travel faster.
A swimming pool on a sunny day has average thermal energy. Also, the entire atmosphere of the earth may not experience the same amount of thermal energy from the sunlight.
Therefore, we can conclude that the most thermal energy out of the following is 1 gallon of boiling water.

A baseball player hits a ball with 36 N of force. With that force, it causes the ball to accelerate at 120 m/s2. What is the mass of the baseball?
Answer:
0.3 kg
Explanation:
This can be dealt with using (a simplified version of) Newton's Second Law:
Force = mass x acceleration
We need to re-arrange the formula to get the mass of the ball isolated, on its own side of the equation. So we get:
mass = force/acceleration
So, now we just need to substitute the number we do have to get:
mass = 36/120 = 0.3 kg

Explanation:
Answer:
A. antibodies
Explanation:
A student fills two syringes: one with air and the other with an equal volume of
water. After capping the syringes, the student applies the same amount of
pressure to the plungers and records observations about the change in volume.
Based on the particle model of matter, which of the following statements best
explains the student's observations that the volume of the gas decreases greatly
but the volume of the liquid does not change noticeably?*
Gases expand to fill their containers but liquids do not because particles of gases are
free to move but particles of liquids are fixed in position.
Gases take the shape of their containers but liquids do not because gas particles
have the ability to flow but liquid particles do not.
Gases can have larger changes in volume than liquids can because gas particles
expand and contract but liquid particles do not.
Gases are more readily compressed than liquids are because there is more space
between the particles in a gas than in a liquid.
Here we need to see the differences between a liquid and a gas, and how that affects the volume and effects of pressure on them.
The correct option is:
Gases are more readily compressed than liquids are because there is more space between the particles in a gas than in a liquid.
So we have two syringes, one with air and the other with water.
The student applies the same amount of pressure to both of them, but as water is denser than air, in a given change dV of volume in the syringe, the mass of water is larger than the mass of air.
This means that for the same pressure, we should expect the change in volume to be smaller in the syringe with water.
Why this happens?
Gases are more readily compressed than liquids are because there is more space between the particles in a gas than in a liquid.
This means that for the air is easier to be compressed (the distance between particles is larger, so the same pressure compresses more a gas than a liquid) and exit the syringe than for the water, and this translates to the change in volume per unit of pressure applied, which is larger for gases than liquids.

C Both mixtures can be physically separated into its components. D Both mixtures are physically combined in the same proportions.
A student makes two mixtures, both made of the same substances. Both mixtures can be physically separated into its components. Therefore, option C is correct.
What is mixture ?A substance made up of two or more separate chemical compounds that are not chemically linked is referred to as a mixture. A mixture is the physical blending of two or more substances while maintaining their distinct identities. It can take the form of solutions or suspensions.
A pure substance is a single sort of matter that cannot be divided into other kinds of matter by any physical methods. A pure substance has a known and consistent composition at all times.
When two or more distinct substances physically join, a mixture is produced that can be dispersed back into its constituent parts. When two or more compounds combine to create a new substance that cannot be broken down into its constituent parts, a chemical reaction takes place.
Thus, option C is correct.

bp’s efforts to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of ________ change.
The British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of regulatory policy change.
The deepwater horizon drilling rig is a semi-submersible, transportable, floating, flexibly oriented drilling rig that could work in sea depths of up to 10,000 feet which is approximately 3,000 meters.
During the explosion that occurred in April 2010, British Petroleum made several efforts to contain the damages made and to prevent further outbreaks of disasters.
Part of the changes was shifting from a blowout preventer that has a specialized valve to seal, manage, and monitor oil and gas wells in order to prevent blowouts to a containment dome (a crucial component of a system meant to control an oil well's underwater blowout).
Therefore, we can conclude that the British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of regulatory policy change.

relative to electrons and electron states, what does each of the four quantum numbers specify
Answer:
(n, l, m sub l, m sub s)
N: principle quantum number (1,2,3,4,etc)
l: angular momentum quantum number, the shape (l has to be at least 1 less than n, but can be 0 depending on n)
M sub l: magnetic quantum number (l determines this number)
M sub s: spin quantum number (can only ever be 1/2 or -1/2)
Explanation:
The principle, azimuthal, magnetic, and spin quantum numbers specify the principle shell, the shape of the orbital, the number of orbitals, and electron spin respectively.
What are the quantum numbers?The set of numbers that describes the position and energy of the electron are called quantum numbers. Four quantum numbers are principal, azimuthal, magnetic, and spin quantum numbers.
Principal quantum numbers (n) designate the principal electron shell of the atom and the most probable distance between the nucleus and the electrons. A larger value of the principal quantum number indicates a large distance between the electron and the nucleus.
The azimuthal quantum number (l) describes the shape of an orbital in which an electron is present. Its value is equal to the total number of angular nodes in that orbital.
The magnetic quantum number describes the total number of orbitals in a subshell and the orientation of these orbitals. The value of the spin quantum number (s) offers the direction in which the electron is spinning and it has only two possible values +½ and -½.

don't have the enzymes necessary to use nitrogen directly from the atmosphere. How
we obtain the nitrogen we need to make proteins and DNA if we can't obtain it from
breathing?
Answer:
We don’t have the enzymes necessary to remove nitrogen from the atmosphere; we get our nitrogen from the food we eat. ^^
Although almost 80% of the atmosphere is made up of nitrogen gas, most living things don't have the enzymes necessary to use nitrogen directly from the atmosphere. We obtain the nitrogen we need to make proteins and DNA, if we can't obtain it from breathing we can get it by eating organic plants and animals.
Why is Nitrogen important for humans?Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things. DNA carries the genetic information, which means the instructions for how to make up a life form.
It is used to make amino acids in our body which in turn make proteins. The human body comprises 3% nitrogen (by mass). It is an essential part of amino acids (makeup proteins), nucleic acids (DNA, RNA), ATP (energy molecule), etc. It is nearly impossible to live without nitrogen.
