velocity (m/s)Kinetic energy varies with the square of velocity so the graph indicates the teams increase in velocity over the course.

5. How fast did the shoes travel? (4 points) a. From where the shoes spilled (48°N, 161°W) to where they first made landfall (49

Leto [7]

Answer:

a) d = 35.0143 Km

t = 188 days

v = 7.76*10⁻³ Km/h

b) d = 28.6356 Km

t = 2165 days

v = 5.51*10-4 Km/h

Explanation:

a. From where the shoes spilled (48°N, 161°W) to where they first made landfall (49°N, 126°W), how many kilometers did they travel?

We can use the equation

d = √(∆N²+∆W²)

⇒ d = √((49-48)²+(126-161)²) = 35.0143 Km

How many days did they take to travel that distance? (You can use November 30 as the date found).

From May 27, 1990 to November 30, 1990 we have

t = 5 days + (30 days/month)*(3 months) + (31 days/month)*(3 months) = 188 days

⇒ t = 188 days = (188 days)*(24 hours/day) = 4512 hours

What was their rate of travel in kilometers per hour?

We use the equation

v = d/t ⇒ v = 35.0143 Km/ 4512 h

⇒ v = 7.76*10⁻³ Km/h

b. From where the shoes spilled (48°N, 161°W) to where they were found in 1996 (54°N, 133°W), how many kilometers did they travel?

We can use the equation

d = √(∆N²+∆W²)

⇒ d = √((54-48)²+(133-161)²) = 28.6356 Km

How many days did they take to travel that distance (use April 30 as the date found)?

From May 27, 1990 to April 30, 1996 we have

t = 5 days + (30 days/month)*(4 months) + (31 days/month)*(6 months) + 29 days + (365 days/ year)*(4 years)+ (366 days/ year)*(1 year)= 2165 days

⇒ t = 2165 days = (2165 days)*(24 hours/day) = 51960 hours

What was their rate of travel in kilometers per hour?

We use the equation

v = d/t ⇒ v = 28.6356 Km/ 51960 h

⇒ v = 5.51*10-4 Km/h

Which continent or region has the most countries that are expected to have a decrease in cropland by 0.3 hectares or more?

Snezhnost [94]

EUROPE

Major reduction in cropland has been noted due to afforestation and urbanization. The growing of grasslands and forests as well as building of cities have slowed down the conversions of spaces into croplands.

The EU is working on the decline slowly but us determined to succeed in establishing croplands.

What physical feature allowed settlers in the Fertile Crescent to grow crops? sea tides flooding rivers natural canals eroding m

Drupady [299]

Hey there! I'm happy to help!

The Fertile Crescent is basically where human civilization started. It stretches from Mesopotamia and across the Mediterranean coast to Egypt. Early civilizations depended on agriculture. To make agriculture, you need a river because it is a good water source to help grow your crops.

If you look at the map I have provided below, you will see that there are tons of rivers. This would make it very easy for settlers to grow crops. This means that sea tides and eroding mountains aren't the answer. I don't think the rivers were flooding and natural canals is an oxymoron because canals are artificial waterways, but this all should give you and idea.

Have a wonderful day! :D

Continued movement of the continental crust on the west side of the San Andreas fault could result in which of the following fea

Mamont248 [21]

Answer:

Option (C)

Explanation:

San Andreas is a prominent example of a transform fault, in which the plates namely the Pacific Plate and the North American plate slide past each other. The movement of the associated plates in this fault is in the right lateral, strike-slip. With the continuous and rapid movement of both the plates in its respective direction, the west side of the fault would get detached from the fault zone and lead to the formation of an island. The movement of the plates along this fault is responsible for the occurrence of shallow focus tremendous earthquakes.

Thus, the correct answer is option (C).
