True or False As most substances are cooled, they expand

Answers

Answer: false. Most substances contract as they cool because the atoms are arranging themselves into a condensed, stable structure. An exception to this rule is water, since it’s atomic structure in a solid state is less dense than its liquid form. Water is an anomaly though, and most substances follow the rule of cooler = more condensed, warmer = expanded.

SC.7.E.6.2 hi how do you do this

Answers

The Rock cycle is a model that describes the formation degradation, and regeneration of rocks as a result of sedimentation magma, and metamorphism. All rocks are made of minerals.

Rock circulation is the process by which rocks change continuously between three types igneous sedimentary and metamorphic. The three processes that transform one rock into another are crystallization, metamorphism erosion, and sedimentation. Any rock can be transformed into another rock by undergoing one or more of these processes. This creates a lock cycle.

Rock circulation is a fundamental concept that describes the transition between three rock types metamorphic igneous, and sedimentary rocks. Simply put it is a set of processes that create and transform rock types within the Earth's crust. Rock cycling by definition is the natural process by which sedimentary igneous, and metamorphic rocks are formed, transformed from one type to another, and destroyed.

A motorcycle can reach a speed of 60 mi/hr much faster than a minivan can

Answers

Answer:

Newton's Second Law of motion

Explanation:

Newton's second law of motion states that 'the rate of change of the momentum of a body is directly proportional to, and in the same direction as, the net force acting on it.' This law applies to the given situation stating that 'a motorcycle can reach a speed of 60mph much faster than a minivan' as the smaller mass accelerates more quickly than the larger. This is because the van would require a more stopping distance as it would be difficult to decelerate due to the heavy mass. While for a motorcycle, it would be much easier to decelerate due to lesser mass. Thus, Newton's second law applies here.

Answers

Answer:

Noble gases are nonreactive elements.

Explanation:

We call Group 18 of the Periodic Table "Noble gases" because they are inert gases. They do not like to bond with other elements.

The reason why is because their outermost shell for electrons is full. These electrons, called valence electrons, are are completely maxed out and therefore makes the element stable. This in turn makes it so that it doesn't really bond with other elements.

Do some research on digital vs. analog recording, and decide which you think gives the most accurate and best quality sound. State the advantages and disadvantages of each in a paragraph. Be sure to back up your opinions with facts, and state your sources.

have 2-6 paragraphs pleasee

Answers

Answer:

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.

Analog refers to a continuously changing representation of a continuously variable quantity. Digital, however, refers to representing these variable quantities in terms of actual numbers, or digits. The last two sentences seem a bit complex, but let’s try to simplify them with an example. If you consider the numbers 1 and 2 on a number line, there are actually an infinite number of points between 1 and 2. This is what analog represents—the infinite number of possibilities between 1 and 2. Digital, on the other hand, only looks at certain number of fixed points along the line between 1 and 2 (for example, 1 ¼, 1 ½, 1 ¾, and 2).

Can you see the difference? Digital takes a few “snapshots” of the number line, while analog takes the whole line into account.

As another example, think of analog vs. digital as the difference between seeing something in real life and watching it on film. When we see something happen in real life, there are no “spaces” between what we see, so we’re watching it happen in analog. Film, however, is actually a series of still photographs that are taken in rapid-fire intervals, and when we see them in succession, it tricks our minds into thinking we’re seeing a continuous flow of movement. So in a manner of speaking, when we watch the event happen on film, we’re watching it digitally, because we’re watching increments of the event, rather than the whole thing in fluid motion. (Not to be confused with digital video vs. film, which is another discussion completely!)

Let’s bring this idea into audio, music, and the studio. Sound occurs naturally in analog–that is to say, sound occurs in a continuous set of waves that we hear with the human ear. (Think of it as a “wavy” line with an infinite number of points along it.) When we capture that sound in a way that represents all the possible frequencies, we’re recording in analog; when we use computers to translate the sound into a series of numbers that approximate what we’re hearing, we’re recording in digital.

Thus, a purely analog recording would be something that was recorded on tape and produced using manual equipment to mix, master and press into a vinyl LP. A purely digital recording would be recorded on a computer program such as Pro Tools, mixed, mastered and produced digitally, and eventually burned onto a CD as an MP3 or audio file.

The most ironic aspect of the debate about digital vs. analog recording is that nowadays a lot of music is a combination of the two.  For example, you might record a song onto analog tape, but mix and master it digitally, or release it on the Internet as an MP3.

So what’s the difference in quality between analog and digital? The idea between digital recording is that our ears and brains technically can’t determine the spaces between the digital values, just like our brains interpret film as continuous motion. However, to many people, analog sound tends to be warmer, has more texture and is thought to capture a truer representation of the actual sound. Digital is felt to be somewhat cold, technical and perhaps lacking in analog’s nuance.

However digital is much cheaper. Recording an album with analog technology can require a whole studio full of equipment, but with digital recording technology, it’s possible to record a whole album in a bedroom on a laptop. And whereas analog technology can wear out or be damaged, digital media can last for an indefinite length of time.

Today many recording artists, both major and independent, record using a mixture of digital and analog techniques. While analog audio does give warmth and a truer sound quality, digital is cheaper to work with and offers more control over the finished product.

Two ice skaters on ice push away from each other. What will be the effect of the forces of their pushing each other if their masses are different?

Answers

Answer:If the masses are different, the lighter ice skater will accelerate faster than the ice skater with more mass.

Explanation:

The lighter skater will accelerate more quickly than the heavier skater if there are mass discrepancies.

used an idea?

According to Newton's third law, the action and reaction forces in any force interaction must be equal and moving in the opposite directions. These pressures, nevertheless, affect a variety of items. In this case, each skater will experience the same amount of force, and if any other horizontal forces, such as friction, operating on each skater in the opposite direction from the pushing force are less than the pushing force, each will accelerate in that direction. The two skater system's center of mass will remain where it is if there is little to no friction to prevent the skaters from moving.

The graph below represents the motion of a car during a 3.0 s time interval. What is the total displacement
of the object at the end of 3.0s

Answers

Answer:

The total displacement of the object is 20 m

Explanation:

Velocity vs Time Graph

It shows the behavior of the velocity as time increases. If the velocity increases, then the acceleration is positive, if the velocity decreases, the acceleration is negative, and if the velocity is constant, then the acceleration is zero.

The distance covered by the car can be calculated as the area behind the graph.

The total area can be calculated in two parts: One triangle from t=0 sec to t=2 sec, and one rectangle from t=2 sec to t=3 sec.

The area of a triangle is

A1= B*H/2, where B is the length of the base, and H is the length of the Height. The base is B=2 seconds, and the height is H = 10 m/s, thus:

A1= (2 sec)*(10 m/sec)/2=10 m

The area of a rectangle is

A2=W*L, where W is the width, L is the length. W=1 sec, L=10 m/s, thus:

A2=(1 sec)*(10 m/sec) = 10 m

Total displacement= 10 m + 10 m = 20 m

The total displacement of the object is 20 m

Answers

Responder:

Explicación:

Fuerza = Masa × aceleración

Dado que aceleración = velocidad final - velocidad inicial / tiempo

Fuerza = m (v-u) / t

Dado

Masa = 1000 kg

v = 15 m / s

u = 0 m / s

t = 20 segundos

Sustituye los valores dados en la fórmula para calcular la fuerza.

F = 1000 (15-0) / 20
