The mass of the Martian atmosphere is approximately 1.04*10^15 kg. This means that the Martian atmosphere has a mass of around 1.04 trillion kilograms.
What does Mars' atmosphere entail?The data from SAM corroborated the composition of the atmosphere on Mars' surface: 95% by volume of carbon dioxide (CO2), 2.6% of molecular nitrogen (N2), 1.9% of argon (Ar), 0.16% of molecular oxygen (O2), and 0.06% of carbon monoxide (CO).
How can we determined this?The mass of the Martian atmosphere can be calculated using the Ideal Gas Law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
To calculate the mass of the atmosphere, we can assume that the temperature is constant and that the atmosphere is at sea level, so we can approximate the volume as the volume of a sphere with a radius of 3396.2 km. The volume of a sphere is 4/3πr^3.
The number of moles can be calculated from the pressure and the volume using the Ideal Gas Law: n = PV/RT.
Once we have the number of moles, we can use the molar mass of the atmosphere to find the mass of the atmosphere.
The calculation for the mass of the Martian atmosphere is as follows:
mass = (4/3)π(3396.210^3)^30.62/(8.314*(273+(-20)))
mass = 1.04*10^15 kg approximately

the relative enrichment in what isotope in venus' atmosphere is evidence of a significant loss of water over time?
The isotope that is relatively enriched in Venus' atmosphere is deuterium, or hydrogen-2.
This is evidence of a significant loss of water over time, as deuterium is heavier than regular hydrogen, and therefore it would be more likely to be lost to space than lighter hydrogen atoms.
What is deuterium?
Deuterium is an isotope of hydrogen with a nucleus that contains one proton and one neutron.
It is also known as heavy hydrogen or hydrogen-2, and is twice as heavy as the more common protium isotope of hydrogen.
Deuterium is used in nuclear reactors and is also a key component in heavy water, which is used in some types of nuclear reactors.

In thermodynamics, each of the system equations (i.e. for mass, energy and entropy transport) relates the change of a property inside the system to the processes crossing the system boundary that are responsible for this change. Which one of the thermodynamic properties (mass, energy or entropy) represented by these system equations is NOT conserved
Entropy is not conserved. Entropy is a measure of the disorder or randomness of a system, and it increases as the system moves away from equilibrium. Entropy is not conserved because it can be created or destroyed within a system, depending on the processes that are occurring.
What is randomness?Randomness is an unpredictable and unstructured phenomenon. It is a lack of pattern or predictability in events. Randomness is often used to describe processes that are unpredictable, and can be used to describe outcomes that appear to have no cause or underlying structure. Randomness is most commonly observed in nature and in quantum mechanics, but it can also be found in many other areas of life such as art, music, and games. Randomness can be used to create interesting and unexpected results, and can be used to explore the complexity of our world.

convergent or divergent depending on how they refract light. what is the difference between these two types of lenses
Light flowing through a converging lens is brought to either a point or focus. The light disperses when seen via a divergent lens. Because they both focus light on your retina, they are converging.
What causes light refract?Since light moves through different material at varying rates, refraction—or a shift in the direction that the flow of light—occurs. Except for when i=00, a light ray's orientation changes when it travels from one substance to another due to a change in speed.
How does light refract?When light enters a material with a differing refractive index at an angle, it refracts (optical density). A shift in speed is what led to this direction change. For instance, light slows down when it passes through water from air and continues to move at a new angle or direction.

if the spring stretches 0.300 m while supporting an 8.2 kg child, what is its spring constant (in n/m)?
The spring constant is 27.333 N/m
The spring constant (k) can be found using Hooke's Law, which states that the force needed to stretch or compress a spring is directly proportional to the distance the spring is stretched or compressed. The proportionality constant is called the spring constant.
The equation for Hooke's Law is:
F = kx
Where F is the force applied to the spring, x is the distance the spring is stretched or compressed, and k is the spring constant.
In this case, the force applied to the spring is the weight of the child (8.2 kg) multiplied by the acceleration due to gravity (9.8 m/s^2)
F=8.2 kg * 9.8 m/s^2
and the distance the spring is stretched is given as 0.3m
Therefore, we can find the spring constant by rearranging the equation:
k = F/x
k = (8.2 kg * 9.8 m/s^2) / 0.3 m
k = 27.333 N/m (Newton per meter)
Therefore the spring constant is 27.333 N/m

a 10 kg bomb is sliding across an ice rink southward at 6 m/s. it explodes. piece 1 with a mass of 2 kg moves southward at 12 m/s. find the direction and magnitude of the velocity of mass 2.
The direction and magnitude of the velocity of mass 2 is 5.6 m/s southward.
What is velocity?Velocity is a vector quantity that measures the rate of change of an object's position in a particular direction.
The direction and magnitude of the velocity of mass 2 can be determined by using the law of conservation of momentum. According to this law, when a system experiences no external force, the total momentum of the system before the explosion must equal the total momentum of the system after the explosion.
Before the explosion, the total momentum of the system is 10 kg * 6 m/s = 60 kg m/s.
After the explosion, the total momentum of the system is 2 kg * 12 m/s + (10 kg - 2 kg) * V2, where V2 is the velocity of mass 2.
Therefore, the equation for conservation of momentum can be written as:
60 kg m/s = 2 kg * 12 m/s + (10 kg - 2 kg) * V2
Solving for V2, we get V2 = 5.6 m/s.

Because temperature affects the physical state of water, it has the greatest impact on how organisms are distributed. Most organisms cannot survive in environments where the temperature is consistently below 0°C or above 45°C.
Since there are 100 units between the freezing (0°C) and boiling (100°C) points of water, the Celsius scale is a centigrade scale. The majority of the world uses this temperature scale, which is also the recognized unit of measurement in science.

we have identified the general type of tire and car. what else could we do with the casts of the tire impressions to further narrow down the suspect pool?
Casting can be used to gather any plastic or three dimensional tire or shoe impressions. Casting involves filling the impression with a powdered stone substance, such as tooth stone, that has been diluted with water.
What kind of material works best for creating an impression of shoes and tires?Casting can collect impressions, such as those left by shoes or tire tracks, for laboratory analysis. These kind of casts are often made of dental stone casting material.
What information is contained in tire impressions?Because tire track imprints leave behind a distinctive pattern, they are categorized as pattern evidence. Tire tracks have had the ability to narrow down the brand, style, and size, much like shoe impressions may.

a 0.25 kg object on the end of a spring moves simple harmonic motion. the spring constant is 200 n/m. the total energy of the system is 6.0 j. determine the amplitude.
A 0.25 kilogram object just on end of the a spring moves in simple harmonic motion with an amplitude of 18.75 cm. 200 n/m is the spring constant.
Why do we use amplitude?Amplitude modulation, or AM, is now utilized for two-way radio communication for aircraft at VHF frequencies and for audio transmission on the long, medium, and short wave bands. Due to the use of superior modulation techniques, it is only used in a very small number of other applications.
Angular velocity ω = 2π / T where T is time period of rotation .
= 2 x 3.14 / .34
= 18.47 rad /s
energy = 1/2 m ω²Α²
6 = .5 x 18.47² x A²
A² = 0.035176
A = .18753
