why does a flight across the united state from San Francisco to new York city take less time than the reverse trip?​

Answers

Answer 1
Because the jet stream and prevailing winds in this country tend to run from west to east. So flights from New York to California have a headwind while flights from California to New York have a tail wind.

Imagine a jet traveling at a true airspeed of 400 knots. With a 100 knot tailwind, it will be traveling across the ground at 500 knots. An identical flight going close to that same altitude but in the opposite direction would only be making 300 knots across the ground. Now do you see why one is less than the other?
Answer 2

Because the country's predominant winds and jet stream often blow from west to east. Therefore, there is a headwind for flights from New York to California and a tailwind for flights from California to New York.

Why does the same flight take longer one way?

According to Forbes, the entire world, including the water and even the atmosphere, rotates in the same direction. Going west requires extra time since the earth is pulling the sky's planes eastward. The real cause of your flight time variations depending on your destination's direction is the jet stream.

Air currents known as jet streams occur at extremely high altitudes, including those that aeroplanes frequently fly in. Your aircraft can rapidly accelerate if it is travelling east following a jet stream. In reality, a Atlantic aircraft from Los Angeles to London in February 2019 was able to reach a speed of 801 miles per hour, shattering the previous record.

Why are many economic activities in emerging countries located in coastal areas or in areas with easy access to the coast?

Answers

Answer: People live near the coast, which means in a 50 kilometre distance from the coast because of the infrastructure built there. ... In coastal regions, there is more non-human life (plants, animals etc.) which means that it is more habitable for humans as there are available resources.

Explanation:

Hope it help

Answer:

Hey!

The main reson why many economic activities happen and are located in the coastal areas is mainly because of 2 reasons...

One: Most of their population (and therefore the countries workforce) live in that area and would not move out because inland is an area where you cannot find work ( or work is low paid)

Two: The coastal areas mean the are locations where ports can be built. This is essential for the exportation of goods and services globally via Cargo Ships which is the most reliable source of shipping goods! And many of the countries factories are built there...

which of the errors in surveying follows normal distribution curve?

Answers

Answer:

Random errors

Explanation:

In  surveying, observation errors can be classified as systematic errors or random errors

Systematic errors are errors that have a non-zero average so that the effect of the error can also observed when we find the average of all the observed data values

Systematic error signifies an deficient model due to the bias in the average of the data obtained

Random errors are the errors remaining after the containing the systematic errors and slip ups. Hence random error are due to the limitations of environment including where the the measurements are made, hence the random error will be experienced to be approximately normal as the number of measurements are increased.

Therefore, random errors in surveying follows a normal distribution curve.

Answer:

b. $129.04

Explanation:

Gross pay refers to salary before taxation. We were given Chuck's salary before tax to be $815.70

Gross pay = $815.70

The following items were withheld:

Federal tax = $56,

Social security tax = 6.2% of gross pay = 0.062 * 815.70 = $50.57

Medicare tax = 1.45% of gross pay = 0.0145 * 815.70 = $11.83

State tax = 19% of Federal tax = 0.19 * 56 = $10.64

To calculate how much of Chuck's salary will be withheld, we have the summation of all the items withheld

Total reduction = $ (56 + 50.57 + 11.83 + 10.64)

Total reduction = $129.04

Hence, $129.04 will be reduced from Chuck's gross pay

What is physical geography?

Physical geography is one of the three main branches of geography. Physical geography is the branch of natural science that deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere.

This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain, analyze, interpret, and understand spatial information. The three branches have significant overlap, however. Mental geography and earth science journals communicate and document the results of research carried out in universities and various other research institutions.

Most journals cover specific publish research within that field, however, unlike human geographers, physical geographers tend to publish in interdisciplinary journals.

Wallace Creek has been offset by 130.0 meters (430 feet) to the right along the fault. The age of stream deposits indicates that this offset began 3700 years ago. Based on these figures, calculate the average rate of movement along this segment of the fault in centimeters per year (or inches per year). Keep in mind that your answer is an estimate of the longterm average, not the expected movement each year.

Total offset in centimeters (or inches):___centimeters (or inches)
Average offset per year:___ centimeters per year (or in./yr.)

Answers

Answer:

a. It is given that the Wallace creek has been offset by 130 meters.

Therefore, total offset = 130 m =13000 cm

b. It is also provided that the offset  began 3700 years ago. Therefore average offset per year:

Total offsets ÷ No. of years = 13000 ÷ 3700

= 3.5123 cm per year

Answer:

So Since cool air cannot retain as much water vapor as warmer air can, the excess water precipitates. Moisture blowing in from the ocean is effectively drained, and the air that moves down the ranges' eastern slopes is usually so dry it cannot produce any more rain in the desert
