The question of analog vs. digital audio is one of the more hotly debated questions in the world of music, film, and media today. Does digital sound better? Does analog sound better? Is there even a noticeable difference?
It’s impossible to understand the difference completely without understanding what distinguishes analog audio from digital audio. A full discussion of these terms is best left to your curriculum and discussions with your mentor in the studio. For now, though, here’s a brief explanation of what these two words mean, and the differences between them.

An astronaut (m = 95 kg) and her tool box (m = 21 kg) is drifting through deep space at a speed of 0.4 m/s [FWD]. In order to change the direction of travel, the astronaut throws her tool box forward. What is the minimum speed of the thrown tool box necessary, so that the astronaut changes direction?
Answer:
The Speed of the throw that is required to create enough impulse, to change the direction of the momentum is: -1.81m/s
Explanation:
m1=95kg
m2=21kg
V1=.4m/s
V2=?
V'=<0 or -.01 at lowest.
for the Impulse formula, I found: m1 x V1 + m2 x V2 = <0
so,
(95) x (.4) + (21) x (V2)=<0
38kgm/s+(21kg x V2)=<0 or -0.01m/s
I found that V2 was equivalent to -1.81, and when you plugin the value, you get the equation
(95) x (.4) + (21) x (-1.81) = -0.01m/s

Describe the difference between continuous reinforcement and intermittent reinforcement.
Answer:
Continuous reinforcement delivers the reinforcement every single time the target behavior is delivered. (For example, if the target behavior for the dog is sitting when the owner says "sit", the treat (reinforcement) would be given whenever the dog follows the command). It follows a schedule-like reinforcement.
Intermittent reinforcement delivers the reinforcement to responses but are not consistent.

Answer:

Explanation:
where its incomplete
Natural selection could act on a population of proto-cells on early Earth, selecting for those that were stable and had self-replicating, catalytic RNA that allowed them to grow and divide to produce similar daughter proto-cells. The correct option is option (B).
Natural selection could act on a population of proto-cells on early Earth. Proto-cells were early, simpler forms of cells that lacked DNA but had self-replicating, catalytic RNA. Through natural selection, those proto-cells that were more stable and had RNA molecules capable of self-replication and catalytic functions would have had a reproductive advantage.
These traits would allow them to grow, divide, and produce similar daughter proto-cells. Over time, this selection process could have led to the development of more complex and stable cellular structures, eventually leading to the emergence of cells that utilize DNA as their genetic material.
Therefore the correct option is option B.

EXPERIMENT: MIXTURES
OBJECTIVES
Utilize a filter to separate a mixture of sand and water.
Summarize your findings.
Many tasks in chemistry involve separating mixtures. For example, crude oil by itself has very few uses, but many important substances are separated from crude oil. In this investigation we will attempt to separate sand from salt water, and salt from water. If you do not have access to sand, you can use small pebbles or BBs.
Before you begin the experiment, hypothesize whether or not you can separate sand from salt water using filter paper. After the experiment summarize your findings in a scientific report. Upload your report below in question 1.
These supplies are needed:
salt
water
sand
a measuring cup
a balance
filter paper
funnel
plastic spoon
two beakers or glasses
Measure 5 grams of salt and 10 grams of sand using the balance.
Mix together the salt and sand in a beaker or glass.
Add one half-cup of water to the salt-sand mixture.
Stir the mixture with the plastic spoon until all the salt is completely dissolved.
To filter the mixture fold the filter in half to form a semi-circle. Fold it again which creates the shape of a triangle. Place the filter paper in the funnel and open one layer of the filter paper and spread it out onto one side of the funnel, and the other three layers onto the other side of the funnel. You may want to wet the filter paper with water so that the filter paper lays flat against the sides of the funnel. Carefully pour the salt water -sand mixture into the funnel and drain the liquid into a beaker or glass.
Remove the filter paper from the funnel and lay it out flat to allow the sand to dry.
Answer:
I found out that you could separate the sand because the filterstion and all the materials uses their elements to filter it out
Findings say that one could separate the sand using the filtration and all the materials uses their elements to filter it out.
What is filtration?Filtration is the technique of segregating the components from a mixture.
In the given experiment, the filter is used to separate a mixture of sand and water.
This experiment can be successfully completed through the filtration process.
Thus, one could separate the sand using the filtration and all the materials uses their elements to filter it out.

Carbon -14 is used to date a palm fossil that originally contained 0.24 grams of carbon -14. The half life is 5700 years. If the fossil is found to be 17,100 years old, how much carbon -14 does it contain now?
Please make sure to show all of your work/process so I can learn how to do it on my own!! thank you
Answer:
Exactly 0.03042 carbon-14 is remaining.
Roughly 0.03 Carbon-14 is remaining. (When/If Multiple Choice)
Explanation:
Not a physics question, this is chemistry, but I'll answer.
First, divide 17,000/5700 to find the t, or time.
t = 2.98245614 or 2.98.
If it originally contained .24 grams, and a half life means x/2,
you would use the formula x/2^p, with p being the number of half lives
(these variables are made up, you can use any you would like)
In 17,000 years, the palm fossil experienced 2.98 half lives.
Thus meaning, using our equation, we would find (.24)/2^2.98
This equals 0.030418784 carbon-14 remaining to be exact.
(For Multiple Choice, it may be required to round to For Multiple Choice, it may be required to round to 3, so .24/2/2/2 or .24/2=.12 then .06 then it equals : .03 Carbon-14)
Carbon -14 is used to date a palm fossil that originally contained 0.24 grams of carbon -14. The half life is 5700 years. If the fossil is found to be 17,100 years old then 0.0303 g of carbon -14 does it contain now.
What is radioactive decay ?The process by which an unstable atomic nucleus loses energy through radiation is known as radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration). A radioactive substance is one that contains unstable nuclei. Alpha decay, beta decay (-decay), and gamma decay (-decay) are three of the most prevalent forms of decay, all of which entail the emission of one or more particles. The mechanism responsible for beta decay is the weak force, while the other two are regulated by electromagnetism and nuclear force. Electron capture is a fourth form of common decay in which an unstable nucleus grabs an inner electron from one of the electron shells.
According to decay formula,
N(t) = N₀ e^(-λt)
Given,
N₀ = 0.24g
t = 17100 years
λ = 0.693/T
Where T is half life.
λ = 0.693/5700 = 1.21 × 10⁻⁴
Putting all the values in the equation,
N(t) = 0.24g e^(-1.21 × 10⁻⁴ ×17,100)
N(t) = 0.0303 g

A ball of play-doh with a mass of 1 kg is thrown at 5 m/s against a wall. The wall causes the play-doh to smash and come to a stop in 0.13 s. What force does the wall apply to the play-doh to make it stop?"
Provide the magnitude of the force applied by the wall (number only).
The magnitude of the force applied by the wall on the ball while smashed is 38.462 newtons.
How to determine the required impact force to stop a ball of Play-Doh(TM)
After a quick reading of the statement we conclude that the impact theorem shall be useful to determine the dynamic force required to stop the ball when smashed. The impulse theorem results from the combination of the Newton's laws of motion, principle of energy conservation and work-energy theorem:
[tex]m \cdot v_{o} = F\cdot \Delta t[/tex] (1)
Where:
m - Mass of the ball, in kilograms.[tex]v_{o}[/tex] - Initial speed of the ball, in meters per second.Δt - Impact time, in seconds. F - Impact force, in newtons.If we know that m = 1 kg, [tex]v_{o} = 5\,\frac{m}{s}[/tex] and Δt = 0.13 s, then the impact force is:
F = (1 kg) · (5 m/s)/(0.13 s)
F = 38.462 N
The magnitude of the force applied by the wall on the ball while smashed is 38.462 newtons. [tex]\blacksquare[/tex]
