The regions of Great Lakes that are having a localized maximum in snowfall are called: B. snowbelts.

<h3>What is a snowbelt?</h3>

A snowbelt can be defined as a geographical region (area) near the Great Lakes in North America that is typically characterized by heavy localized maximum in snowfall, especially off the southern and eastern shores.

This ultimately implies that, snowbelts are the regions of Great Lakes that are having a localized maximum in snowfall.

In conclusion, hurricanes are more likely to form in the tropical Atlantic during a La Nina year because it weakens the wind shear.

I NEED HELP THIS DUE TODAY! ”What are 12 facts about ENERGY?” 50 points if answered!!
romanna [79]

Answer:

The average U.S. home uses about 11,000 kilowatt hours of electricity per year.

Electricity travels at the speed of light – over 186,000 miles per second.

Electricity can be produced from fossil fuels, large hydro power plants, nuclear power plants, or renewables like wind or solar.

Birds and other small animals can perch on power lines without being electrocuted unless they simultaneously touch another line, which would create a complete circuit.

For electricity to come into your home, it travels from generation facilities to a high-voltage switchyard, to transmission lines, to a substation, to a distribution line, to a transformer, to your house.

Geothermal energy comes from the Earth. It consists of hot water and hot rock that’s just a few miles beneath the Earth’s surface, and can go even deeper to very hot molten rock called magma. It’s considered clean and sustainable.

Renewable energy comes from perpetual sources like wind, solar or geothermal. Most electricity, though, is produced from nonrenewable sources like fossil fuels (coal, crude oil, natural gas, and uranium). They are nonrenewable because there is a finite amount of them that were formed from buried remains of plants and animals that lived millions of years ago. They cannot be replenished the way renewable energy sources can.  

In the U.S., the areas most favorable for geothermal energy use are in Nevada, Oregon, Idaho, Arizona, Utah, Colorado and New Mexico. Geothermal plants are located where water has seeped into the Earth’s crust, and they force the water back up through permeable rock.

Saving energy can be as simple as switching from incandescent light bulbs to CFL or LED versions.  

About 40 percent of energy from all resources is used for electricity, which means that our resources are used more for that purpose than for any other.

 

CFL bulbs consume 80% less electricity than standard bulbs

Natural Gas Facts

When we think about energy facts, we usually focus on electricity, but our homes use natural gas, too! Natural gas is a gaseous mixture of hydrocarbon compounds used as fuel to generate electricity. In order to be used in your home, it must first be processed and converted into dry natural gas. To learn more about its use in your home, check out the natural gas facts below.

 

10 Facts about Natural Gas

The main component of natural gas is methane, with butane, propane, ethane, or pentane sometimes included.

The “rotten egg” smell of natural gas is actually added by power companies so that your nose can detect a gas leak. In its initial state, natural gas is colorless and nearly odorless.

Most natural gas is delivered via pipeline; there are enormous networks that deliver it to processing facilities, which then transport it to the end consumer. Along the route, there are compressors and metering stations to monitor pressure, flow, and leaks.

When natural gas is transported between countries, it travels by ship in liquid form. This way, it takes up less volume. Once it reaches land, it is regasified (or returned to gas form) and sent to the pipelines for distribution.

In the U.S., there are more than 2.5 million miles of pipeline used for transporting natural gas directly into homes and businesses.

It’s reported that 85 percent of the natural gas consumed in the United States is produced domestically.

Energy facts suggest that natural gas is one of the cleanest choices for fossil fuels. It produces less carbon and pollution than other fossil fuels.

The natural gas and oil industry employs nearly 10.3 million Americans. That’s equals to about 5.6 percent of all of U.S. employment.

Approximately 66 million homes and 5 million businesses in the U.S. use natural gas as an energy source.

This is one of the more important natural gas facts: transportation is one of the most difficult and fragile aspects to its use. Because the main component to natural gas is methane, which is a potent greenhouse gas, undetected leaks can contribute to climate change.  

The "rotten smell" is added to the natural gas so your nose can detect a gas leak

Halley's comet orbits the sun roughly once every 76 years. It comes very close to the surface of the Sun on its closest approach
Licemer1 [7]

Answer:

r1 = 5*10^10 m , r2 = 6*10^12 m

v1 = 9*10^4 m/s

From conservation of energy

K1 +U1 = K2 +U2

0.5mv1^2 - GMm/r1 = 0.5mv2^2 - GMm/r2

0.5v1^2 - GM/r1 = 0.5v2^2 - GM/r2

M is mass of sun = 1.98*10^30 kg

G = 6.67*10^-11 N.m^2/kg^2

0.5*(9*10^4)^2 - (6.67*10^-11*1.98*10^30/(5*10^10)) = 0.5v2^2 - (6.67*10^-11*1.98*10^30/(6*10^12))

v2 = 5.35*10^4 m/s

You throw a bouncy rubber ball and a wet lump of clay, both of mass m, at a wall. Both strike the wall at speed v, but while the
lana [24]

Answer:

<em>The fifth option is the correct answer: mv; 2 mv</em>

Explanation:

<u>Change of Momentum</u>

Assume an object has a momentum p1 and after some interaction it now has a momentum p2, the change of momentum is

\Delta p=p_2-p_1

The momentum is computed as

p=mv

Where m is the mass of the object and v its speed. Now let's analyze the situation of both the ball and the clay.

The clay has an initial speed v and a mass m, thus its initial momentum is

p_1=mv

When it hits the wall, it sticks, thus its final speed is 0 and

p_2=0

The change of momentum is

\Delta p=0-mv=-mv

The absolute change is mv

Now for the ball, the initial condition is the same as it was for the clay, but the ball hits back at the same speed, thus its final momentum is

p_2=-mv

The change of momentum is

\Delta p=-mv-mv=-2mv

The absolute change is 2mv

The fifth option is the correct answer: mv; 2 mv

The kinetic friction force between a 60.0-kg object and a horizontal surface is 50.0 N. If the initial speed of the object is 25
Vikki [24]

Answer:

375 m.

Explanation:

From the question,

Work done by the frictional force = Kinetic energy of the object

F×d = 1/2m(v²-u²)..................... Equation 1

Where F = Force of friction, d = distance it slide before coming to rest, m = mass of the object, u = initial speed of the object, v = final speed of the object.

Make d the subject of the equation.

d = 1/2m(v²-u²)/F.................. Equation 2

Given: m = 60.0 kg, v = 0 m/s(coming to rest), u = 25 m/s, F = -50 N.

Note: If is negative because it tends to oppose the motion of the object.

Substitute into equation 2

d = 1/2(60)(0²-25²)/-50

d = 30(-625)/-50

d = -18750/-50

d = 375 m.

Hence the it will slide before coming to rest = 375 m
