Answers

Answer 1

Answer:

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. Stars start their lives as clouds of dust and gas.

What happens in winter in the Northern Hemisphere when the North Pole tilts away from the sun?
A. Rays of sunlight do not hit the Northern Hemisphere at all. There is no daylight and it is
extremely cold.
B. Rays of sunlight hit less directly. The days are shorter and temperature colder.
C. Rays of sunlight hit the Northern Hemisphere directly. Days are long and
temperatures are warmer.
D. Rays of sunlight do not affect the day length or temperature in the Northern
Hemisphere.

Answers

Answer:

B. Rays of sunlight hit less directly. The days are shorter and temperature colder.

Explanation:

When the north pole tilts away from the sun, the sun's rays are displaced below the equator line, that is, towards the southern hemisphere. It causes the northern hemisphere to receive fewer solar rays and to receive them indirectly, which leaves the atmosphere cooler and decreases the length of the day. This moment coincides with winter and autumn in the northern hemisphere. This inclination of the north pole lasts six months and after that period the moment of inclination of the south pole begins, which causes the sun's rays to be displaced towards the northern hemisphere.

Michelle's camping tent is in the shape of a triangular prism She wants to reinforce the fabric of her tent with a waterproofing treatment Find the total surface area, including the floor of Michelle's tent shown below. Round your answer to the nearest square foot.​

Answers

Answer:

208

Explanation:

The total surface area of a triangular prism can be calculated from its bases, and height. From the image of the tent, its surface area is calculated to be 52.8  m²which is equal to 568 square foot.

What is the surface area of a triangular prism ?

The triangular prism is a kind of geometry contains two triangular faces and two rectangular bases. The area of the triangular base is calculated as follows:

surface area = bh + (s1 + s2+ s3)L

Where b be the base of the triangle and L be the length of the prism. The s1, s2 and s3 be the three sides of the triangle.

From the tent image.

base of the triangle = 3 m

Hight h = 2.6 m

s1 = s2 = 3 m

s3 = base = 3 m

length of the prism L = 5 m

Then,

the surface area of the tent with the shape of triangular prism is:

S = 3 m×2.6 m +  (3 +3 + 3 m)5 m =  52.8 m²

1 m² = 10.76 sq feet

then 52.8 m² = 568 square foot

Therefore, the total surface area of the tent is 568 square foot.

What does the climate and environment have to do with sustainable development?​

Answers

Answer:

Explanation:

Sustainability could simply be defined as the reasonable maintainance at present to prevent compromising the availability of such resources in the future. Sustainable development has become a popular term in our changing environment today especially as the need for energy as soared and the need to mitigate and adapt to the use of more climate friendly resources has become increasingly important. We need to tailor our needs and wants in such a way that it does not jeopardize the environment the future generations will live in. Changes in climate and weather patterns is on the horizon largely due to continued emission of green house gases (mostly carbon) into the atmosphere, these emissions will most likely increase as the energy demands have risen largely due to population growth. Without sustainable development strategies, the environment runs the risk of being challenged by food security, water level changes all due to changes in climatic condition triggered largely by human activities.

Definition?

Answers

Explanation:

Monsoon

Monsoon is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea.

Atmospheric pressure

Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth. A standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

(Extra Info) P_h= P_0 e

P_h = pressure at height h

P_0 = sea level pressure

g = acceleration due to gravity

k = Boltzmann's constant (ideal gas constant divided by Avogadro's number)

T = absolute temperature

m = mass of one air molecule

Upwind

In the direction from which the wind is blowing.

Downwind

In the direction opposite to the direction the wind is blowing.

Orographic effects

The orographic effect occurs when air masses are forced to flow over high topography. As air rises over mountains, it cools and water vapor condenses. As a result, it is common for rain to be concentrated on the windward side of mountains, and for rainfall to increase with elevation in the direction of storm tracks.
