Dimensional analysis: 1.35 kilometers per second = 3019.86 miles per hourFurther explanation

Dimensional analysis, also known as factor-label method or unit-factor method, is a method used to convert one unit to a different unit.

Dimensional Analysis is a very basic aspect of measurement and has many applications such as in applied physics.

There are seven steps to do dimensional analysis:

Identify the starting factor. Identify answer units. Determine conversion factors needed. Ensure the conversion factors are in the correct format. Cancel units that appear in both the numerator and denominator. Simplify the fractions. Solve.

1.35 kilometers per second= ? miles per hour

So first we identify the starting factor:

1.35 km/second * 0.621 miles/km = 0.838 miles/sec (the km cancel out)

Next, we need to convert from seconds into hours. There are 60 second in a minute and 60 minutes in an hour, so there are 60*60=3600 second/hour. Thus,

0.838 miles/second * 3600 second/hour = 3019.86 miles/hour.

Most of the information you process while driving is what you

Answers

Mostly you process information through sight while you are driving. Think about when you are at a stop sign. Firstly, you have to see the stop sign to know to stop at that particular location. Secondly, you would look around to make sure no one is driving on the cross road and no one is turning in front of your vehicle. Then, only after seeing the location is clear would you drive forward in your desired direction. While sight is the main sense used while driving, a good driver is also noticing what they hear as well. Ambulances, cops, and even trains inform of their location by sound. With these two senses being used, a good driver can drive safely.

Answers

I think the answer would be specialization?

Within a major, students can choose to study a specific area. This is called a specialization. Thus, option B is correct.

What is specialization?

Specialization is defined as the process of focusing resources (labor, capital, and land) on producing a small variety of goods. Because not everyone must farm, an excess of food leads to employment specialization. As a result, some people are able to pursue other interests, like metalworking.

People who can devote time to their crafts become skilled at them and make a living from them, which leads to the development of new technologies. Because some individuals were able to opt out of food production due to the surplus food production produced by other communities, specialized professions and related classes began to emerge.

Therefore, Within a major, students can choose to study a specific area. This is called a specialization. Thus, option B is correct.

Dimensional analysis 134 miles = ? Inches

Answers

134 mi/1 = 5280 ft/1 mi = 12 inches/1 ft
(So first, the miles unit is crossed out, so the next unit would be feet. There are 12 inches in 1 foot. So now ft are crossed out and remaining unit is inches. Multiply across, so 134 x 5280 x 12  = 8490240.)

In 134 miles, there are 8,490,240 inches.




Dimensional analysis 134 miles = 8490240. We can use a conversion factor of 63,360 inches per mile to convert 134 miles to inches.

The conversion factor of 63360 inches per mile can be used to convert 134 miles to inches.

12 inches/1 foot 5280 times 12 equals 63360

134 miles is equal to 134 63360 inches.

8,490,240 inches equal 134 miles.

We may eliminate the miles unit using dimensional analysis and replace it with inches by setting up the conversion factor as a fraction with miles in the denominator and inches in the numerator.

Answers

Answer:

D - Provide Labor and Buy Goods / edu

Explanation:

In order for the economy to be strong, individuals must produce goods and buy goods. The correct option is c.

What is economy?

An economy is a network of interconnected production and consumption activities that ultimately determine resource allocation within a group.

The overall production and consumption of goods and services meets the needs of those who live and work within it.

Producing goods is required to create value and generate income in the economy, whereas purchasing goods is required to generate demand for those goods and stimulate economic growth.

Paying workers and providing labor are important components of economic activity, but they are insufficient to create a strong economy on their own.

Personality refers to the unique set of traits, behaviors, and characteristics that define an individual. It is often believed that personality is fixed and unchanging, but recent research has shown that people have the ability to change and develop their personalities over time.

What makes people's personalities change?

Mental diseases including bipolar disorder, depression, or personality disorders can lead to personality changes. Physical conditions including a urinary tract infection (particularly in elderly persons), a concussion, or a brain tumor may also be to blame. Making a successful treatment possible requires an understanding of the cause.

Personality change can also be influenced by social and cultural factors. People's personalities are often shaped by the norms and values of the society and culture they live in. For example, someone who grows up in a collectivist culture may value cooperation and harmony over individual achievement, while someone who grows up in an individualistic culture may value independence and self-reliance.

Dimensional analysis 8.9x10^5 tons= ? Ounces

Answers

We know that there are 32,000 ounces in 1 ton. Therefore we use this conversion factor in our calculations. So to convert:

8.9 x 10^5 tons * (32,000 ounces / 1 ton) = 2.848 x 10^10 ounces

 

Writing in 2 significant figures:

2.85 x 10^10 ounces

Answer: 28.48x10^9 ounces.

Explanation:

We know that 1 ton = 32000 ounces.

Now, if we have 8.9x10^5 tons, how many ounces we have?

we know that each ton is equivalent to 32000 (or 3.2x10^4) ounces, so we need to multiply the number of tons by the number of ounces that each ton has:

8.9x10^5* 3.2x10^4 = (8.9*3.2)x(10^5*10^4) = (28.48)x10^(5+4) = 28.48x10^9

So 8.9x10^5 tons are equivalent to 28.48x10^9 ounces.
