Explanation:

Sample Response: The object starts away from the origin and then moves toward the origin at a constant velocity. Next, it stops for one second. Finally, it moves away from the origin at a greater constant velocity.

What did you include in your description? Check all that apply.

The object starts away from the origin.

The object moves toward the origin at a constant velocity.

The object stops for one second.

The object moves away from the origin at a greater constant velocity.

Answer 2

The circled vectors represent speed.

What is speed?

The is the ratio of distance traveled to time of motion. Speed is a scalar quantity because it has only only magnitude.

From the map, as the magnitude (size) of the green arrows changes, the size of the circled arrows changes accordingly.

Also, the direction of the circled arrow was constant for both top and bottom arrows.

Velocity changes with direction BUT speed does not change with direction, and has a complete meaning with only magnitude.

Thus, the circled vectors represent speed.

uhhh speed of box??? I think

The factor affecting the amount of work done against friction is the distance traveled by the box.

The work done against friction is energy dissipated in reducing frictional force along the horizontal surface.

The magnitude of the work done in reducing the frictional force along the horizontal surface is given as;

W = μFd

where;

μ is the coefficient of frictionF is applied horizontal forced is the horizontal distance traveled by the box

Thus, we can conclude that the factor affecting the amount of work done against friction is the distance traveled by the box.

Keisha has two large dogs and a small dog. The dogs like to play tug-the-rope together. Each of these three diagrams shows one way that the dogs play together with the rope. Look at each arrow and the number that goes with it. They show the direction and amount of force each dog exerts on the rope. There are three illustrations of two dogs pulling at a toy rope.


The left art should show two big dogs pulling on a rope toy each pulling with a force of 20N in the opposite direction. The middle art shows a big dog on left pulling to the left on the rope toy with a force of 20N and a little dog pulling to the right with a force of 12N. The right art shows the rope toy tied to a post, with both dogs pulling on different parts of the toy and in the same direction. One large dog pulls with a force of 20 N and the small dog pulls with a force of 12 N.


Explain whether the forces shown in each diagram are balanced or unbalanced. Use math-based evidence to support your claim for each diagram.

Answers

Answer:

The answer is unbalanced

Explanation:

Though cases like these are not really how the science will be used, they illustrate the principle.

If the left art shows two big dogs pulling on a rope toy each pulling with a force of 20N in the opposite direction. The middle art shows a big dog on left pulling to the left on the rope toy with a force of 20N and a little dog pulling to the right with a force of 12N. The right art shows the rope toy tied to a post, with both dogs pulling on different parts of the toy and in the same direction. One large dog pulls with a force of 20 N and the small dog pulls with a force of 12 N. The atomic theory has been of priceless value to chemists, but it has more than once happened in the history of science that a hypothesis, after having been useful in the discovery Present and the co-ordination of knowledge, has been aban- position doned and replaced by one more in harmony with later of the discoveries

The amount of force exerted in each direction in the rope determines if the force in play is balanced or unbalanced ;

Left art : 20N = 20N (Balanced) Middle : 20N > 12N (Unbalanced) Right art : 20N > 12N (Unbalanced)

To determine if the force acting in two direction is balanced or unbalanced, we calculate the net force acting on the object.

The net force = Force 1 - Force 2

If the netforce = 0 ; then the force is balanced, if otherwise , then it is unbalanced.

Left art :

Net force = 20N - 20N = 0 N

Right art :

20N - 12N = 8N (direction of the 20N force)

Middle :

20N - 12N = 8N (direction of the 20N force)

Therefore, the value of the net force determines if the force is balanced or not.

Answers

Answer:

Explanation:

1) weight = mg = 9.81*1000 = 9810 Newtons

2) frictional force = normal force *

we must assume that the vehicle is on a flat surface so therefore the normal force is the same as the weight of the vehicle.

frictional force = 9810 * 0.55 = 5 395.5 N

3) acceleration: F = ma, a = F/m

assume that only the frictional force is acting on the vehicle:

a = 5395.5/1000 = 5.3955 m/s

4) the car decelerates at 5.3955m/s

over 6 seconds, the car decelerates by: 32.37m/s

5) original speed = 29m/s final speed = 29-32.37 = -3.37m/s which is a negative number, therefore the vehicle would have stopped before it hit the rail.

6) to get to the rail, the vehicle would have had to be traveling at least 32.37m/s which is 72.41 mph

How to calculate weight on
mars?

Answers

it takes the weight of an object on earth and converts it to Martian weight, the formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2. To find the Martian weight, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. This calculates the mass of the object. Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.711m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on mars.

So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.

In the lab, a student is investigating the effects of texting and driving on reaction time. A
student determines his/her reaction time by having a friend release a meter stick at
random intervals while the driver sends text messages. The student, on average,
catches the meter stick after it has traveled 0.64 m.
How far will the student
travel in a car moving at 25 m/s horizontally before reacting?

9.0 m
0.64 m
69 m

Answers

We know that we can write the speed of something as the quotient between the distance it moves and the time it takes to move that distance.

speed = distance/time

Using this, we will find that the correct option is the first one, 9.0 m

The information we know is:

The student, on average, catches the meter stick after it has traveled 0.64m

We need to transform this into time.

Assuming that the meter stick is just released, the only acceleration it will have is the gravitational one, so we have:

a(t) = -9.8m/s^2

To get the velocity of the stick we need to integrate over time, as the it is just released, it will not have initial velocity, thus the constant of integration is zero:

v(t) = (-9.8m/s^2)*t

To get the position equation we need to integrate again, and as the initial position is relative, we can define it as zero, so again the constant of integration is zero:

p(t) = (1/2)(-9.8m/s^2)*t^2

p(t) = (-4.9 m/s^2)*t

We know that the student catches the stick after it traveled (downwards) 0.64m

Then we need to solve:

-0.64m =  (-4.9 m/s^2)*t

√[(-0.64m)/(-4.9m/s^2)] = t = 0.36s

So the reaction time of the student is 0.36 seconds.

Now we can use the first equation:

speed = distance/time

And rewrite it as:

distance = speed*time

So if the car moves at 25m/s and the student needs 0.36 s to react, the distance that he/she will move in that time frame is:

d = (25m/s)*0.36s = 9.0m

So the correct option is the first one.

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.
