Information needed to answer:
A pharmaceutical spectroscopist places a sample of a pain reliever into a mass spectrometer and obtains data about different compounds within the sample. The image below shows a mass spectrograph of the data. The relative intensity, shown on the vertical axis, indicates the relative amount of each compound in the sample. The m/z (mass to charge) ratio, shown on the horizontal axis, is related to the molecular mass of each compound.
Question:
Describe two observations you can make from the graph. (Graph is below)

Why is it important to know how the sun's energy affects the lower atmosphere if you are planning to harness the power of moving air?
It is important to know the affects of temperature on pressure and thereby on winds. At high temperature, the pressure will be high and thus, the winds will pass from that area.
What is winds?
Wind is the passage of air through the atmosphere. The uneven distribution of temperature leads to the difference in pressure. The pressure gradient results in wind.
Air pass from high pressure area to low pressure area. According to Gay- Lussacs law, at the pressure gases is directly proportional to the temperature.
Hence, as the temperature increases, pressure in that area increases, leads to air currents to the opposite direction. This will definitely affects harnessing.

How do gases in Earth's atmosphere keep the amount of energy that Earth receives from the sun from being too much, or more than Earth and its organisms can tolerate?
Answer: The gases help shield the Earth from harmful UV rays that could damage life on it. They also help prevent extreme day and night temperatures.
Explanation:
The atmosphere is a gaseous layer or the blanket of the gases that surrounds the planet and is held at a place by gravity. It is essential as it comprises various gases needed to maintain the temperature and the climate of the planet.
What is the role of the atmosphere?The atmosphere is crucial for life to be maintained on the planet as it balances the amount of the sun rays and heat to enter and exit the planet's surface and environment.Various gases like nitrogen, carbon dioxide, oxygen, neon, helium, methane etc. are essential as plays an important role in blocking the harmful ultraviolet rays from the sun and traps a certain amount of heat to maintain the temperature of the planet.Thus, protection and maintaining temperature is the role of the atmosphere.

What makes up fog? What happens to the water molecules that cause them to turn from fog into rain?
When the water vapors condense and water molecules combine to make tiny water droplets in the air is known as fog. The precipitation of fog when the humidity of the fog attains 100% and begins to unite into larger droplets or rain.
How is fog formed?Fog is the tiny water droplets suspended in the air at or near the Earth's surface. Fog is a type of low-lying cloud and is heavily influenced by nearby bodies of water and wind conditions.
When the environment is very humid then Fog happens. The air around the surface of the earth can hold a certain amount of water vapor in a gaseous state. As more water fills the air, the air becomes more humid is known as humidity.
Water vapor unites to make tiny liquid water droplets that hang in the air during the condensation of the water molecules. Water vapor is a gas and invisible but the fog can be seen with our eyes. The fog turns into rain when the humidity is almost 100% by combing into larger droplets.

After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.
Body temp while eating = 37*c After Running = 40*c
Answer: 1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
Explanation: When Pedro ate breakfast, he consumed the chemical energy, which is a form of potential energy, that was stored in his breakfast. When he went for a run, that chemical energy transformed into mechanical energy, which is a form of kinetic energy. That mechanical energy then transformed into thermal energy while he was running, which is how his temperature raised after he was finished running. The energy in this system was conserved as it was transformed because the energy was constant. As the energy was being transformed between different types, the total amount of energy remained unchanged.
The potential energy stored in the body chemically. That potential energy is then released when the body put in motion.

Explain the relationship between pitch and frequency.
The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. ... That is, two sound waves sound good when played together if one sound has twice the frequency of the other.

Answer:
40.3 for the unit that represents the minimum amount of magnesium oxide I beilieve.
Explanation:
Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition. Taking just one atom of Mg and one atom of O you will get a mass of 16.0 + 24.3 = 40.3.

What is the relationship between kinetic energy and mass?
A Kinetic energy increases as mass increases.
B Kinetic energy decreases as mass increases.
C Kinetic energy must be less than an object's mass for movement to occur.
D Kinetic energy and mass must be equal for movement to occur.
Answer:
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity.Explanation:
