How do greenhouse gases such as CO2 and N2O contribute to an increase in Earth’s atmospheric temperature?
A.
Greenhouse gases interact with infrared photons and reflect them back to Earth’s surface.
B.
Greenhouse gases chemically react with one another, releasing heat in the process.
C.
Greenhouse gases agitate visible light photons, increasing the photons’ temperature and motion energy.
D.
Greenhouse gases generate internal heat through radioactive decay, similar to the core of Earth.
Answers
Answer:
The answer is A
Explanation:
The earth naturally maintains the heat energy balance by absorbing a sufficient amount of sunlight energy by the terrestrial land and then reverting back the excess sunlight energy back to the space. The increase in abundance of greenhouse gases in the atmosphere results in absorption of sunlight energy which contains infrared photons this is responsible for increasing the global temperature levels hence, responsible for global warming. These infrared photons are reflected to the earth surface instead of sending back to the space. This is responsible for disturbing the heat balance.
Greenhouse gases interact with infrared photons and reflect them back to earth’s surface, hence option A is correct.
How does greenhouse gases rise in earth’s atmosphere?The burning of fossil fuels, logging of forests, and raising of livestock all have a rising impact on the climate and temperature of the planet.
This increases the greenhouse effect and causes global warming by adding a significant amount of greenhouse gases to those that are already present in the atmosphere.
The earth naturally maintains the balance of heat energy by receiving enough solar energy through the terrestrial land and then returning any excess energy to space.
Therefore, greenhouse gases such as CO₂ and N₂O interact with infrared photons and reflect them back to earth’s surface.

An investor buys $750 worth of a stock, which earns an average rate of 1. 2% compounded 4 times per year. Which equation represents the value of the stock, V, after t years?
Answers
The equation representing the value of the stock, V, after t years is V = 750(1.003)^(4t).To represent the value of the stock, V, after t years, we can use the formula for compound interest:
V = P(1 + r/n)^(nt)
Where:
V is the value of the stock after t years
P is the initial investment (in this case, $750)
r is the annual interest rate (1.2%)
n is the number of times interest is compounded per year (4)
t is the number of years
Substituting the given values into the formula, we have:
V = 750(1 + 0.012/4)^(4t)
Simplifying further:
V = 750(1 + 0.003)^(4t)
V = 750(1.003)^(4t)
Therefore, the equation representing the value of the stock, V, after t years is V = 750(1.003)^(4t).

Ammonia production is the largest consumer of nitrogen and is the gatewaycompound to most other nitrogen compounds produced industrially. Enormous quantities of ammonia are produced worldwide.
The majority of all ammonia and ammonium nitrate produced is for use as fertilizer. Approximately 70% of all NH3 produced is directly used for fertilizer. Farmers inject the pressurized liquid ammonia into the soil.
Ammonia is so soluble in water and has such a high affinity for polar groups such as hydroxyl groups that the ammonia is almost instantly taken up by the soil and very little is lost to the atmosphere.

If both systems have the same mass, what is the ratio ka/kb of their spring constants?
Answers
The ratio ka/kb of the spring constants is dependent on the ratio of accelerations and the ratio of displacements for the two systems.
The ratio ka/kb of the spring constants for two systems with the same mass can be determined by comparing their equations of motion. In the equation F = -kx, where F is the force applied, k is the spring constant, and x is the displacement, we can set up the following equations for the two systems:
System 1: F1 = -ka*x1
System 2: F2 = -kb*x2
Since both systems have the same mass, the force applied can be written as F = m*a, where m is the mass and a is the acceleration. Therefore, for both systems:
System 1: m*a1 = -ka*x1
System 2: m*a2 = -kb*x2
Dividing these two equations, we get:
(a1/a2) = (ka/kb) * (x1/x2)
From this, we can conclude that the ratio ka/kb is equal to the ratio of the accelerations a1/a2 multiplied by the ratio of displacements x1/x2.

A galvanic cell at room temperature with a standard cell potential of 0.84 V, which transfers three moles of electrons and is associated with a reaction quotient of 276, will have a cell potential of what value (in volts)?
Answers
To determine the cell potential of the galvanic cell, we can use the Nernst equation, which relates the standard cell potential (E°), the reaction quotient (Q), and the cell potential (E) at non-standard conditions. From this, the cell potential comes out to be 0.824 V.
The nernst equation is:
E = E° - (RT/nF) × ln(Q)
Where:
E is the cell potential at non-standard conditions
E° is the standard cell potential
R is the gas constant (8.314 J/(mol·K))
T is the temperature in Kelvin
n is the number of moles of electrons transferred in the balanced equation of the cell reaction
F is the Faraday constant (96,485 C/mol)
ln is the natural logarithm
In this case, the standard cell potential (E°) is given as 0.84 V, the number of moles of electrons transferred (n) is 3, and the reaction quotient (Q) is 276. We need to convert the temperature to Kelvin.
Let's assume the temperature is room temperature, which is approximately 25 °C or 298.15 K.
Plugging these values into the Nernst equation:
E = 0.84 V - (8.314 J/(mol·K) × 298.15 K / (3 × 96,485 C/mol) × ln(276)
Calculating this expression will give you the cell potential (E) in volts.
After evaluating this expression, the cell potential (E) is approximately 0.824 V.
Hence, the cell potential is 0.824 V

The density of silver is 10.5g/cm3. A piece of silver with a mass of 61.3g would occupy a volume of _________ cm3.
Answers
The density of silver is 10.5g/cm³. A piece of silver with a mass of 61.3g would occupy a volume of 5.83 cm³.
To find the volume of a piece of silver with a mass of 61.3g and a density of 10.5g/cm³, you'll need to use the formula for density, which is:
Density = Mass / Volume
In this case, you know the density (10.5g/cm³) and the mass (61.3g), so you can rearrange the formula to solve for the volume:
Volume = Mass / Density
Now, plug in the given values:
Volume = 61.3g / 10.5g/cm³
Volume ≈ 5.83 cm³
So, a piece of silver with a mass of 61.3g would occupy a volume of approximately 5.83 cm³. This calculation is based on the relationship between mass, volume, and density, where density is the amount of mass per unit of volume. In this example, silver has a high density, meaning it is heavy for its size, and the given mass of 61.3g results in a relatively small volume of 5.83 cm³.

Explanation:
Matter is anything that has mass and takes up space. The mass of an object measures the amount of matter or substance the object contains.
Volume is the measure of the amount of space taken up by the object.
The SI units for mass and volume are kilogram (kg) and cubic meter (m³) respectively.
Generally, matter exists in three (3) distinct phases and these are;
1. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.
2. Liquid: it is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.
3. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.
