Answers

Answer:

The THREE processes responsible for the loss of the sun's heat in the atmosphere - conduction, convection, and radiation

Explanation:

The three processes by which the sun losses heat are as follows -

conduction, convection, and radiation

In conduct a direct medium contact  is required to transfer heat while in radiation no medium/contact  is required to transfer heat.

While in convection, heat is transferred by actual motion of matter.

Determine whether each set of points make a right triangle using the Pythagorean Theorem. 1. A(3 , -4) B(-4 , 3) C(0 , 0) 2. O(2 , 5) P(-1 , 3) Q(7 , 4) 3. T(1 , 1) U(3 , 3) V(5 , 1)

Answers

Answer:

[tex]1.\ A(3 , -4)\ B(-4 , 3)\ C(0 , 0)[/tex] -- Not right triangle

[tex]2.\ O(2 , 5)\ P(-1 , 3)\ Q(7 , 4)[/tex] -- Not right triangle

[tex]3.\ T(1 , 1)\ U(3 , 3)\ V(5 , 1)[/tex] -- Right triangle

Explanation:

Required

Determine whether the given points make a right triangle

[tex]1.\ A(3 , -4)\ B(-4 , 3)\ C(0 , 0)[/tex]

First, calculate the distance between each point using:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

[tex]AB = \sqrt{(3 - -4)^2 + (-4 - 3)^2}= \sqrt{98} = 7\sqrt 2[/tex]

[tex]BC = \sqrt{(-4 - 0)^2 + (3 - 0)^2}= \sqrt{25} = 5[/tex]

[tex]AC = \sqrt{(3 - 0)^2 + (-4 - 0)^2}= \sqrt{25} = 5[/tex]

From the above computations, the longest side is AB.

So;

[tex]AB^2 = BC^2 + AC^2[/tex] --- Test of Pythagoras

[tex](7\sqrt 2)^2 = 5^2 + 5^2[/tex]

[tex]98 = 25 + 25[/tex]

[tex]98 \ne 50[/tex]

The above points do not make a right triangle

[tex]2.\ O(2 , 5)\ P(-1 , 3)\ Q(7 , 4)[/tex]

Calculate distance

[tex]OP = \sqrt{(2 - -1)^2 + (5 - 3)^2}= \sqrt{13}[/tex]

[tex]PQ = \sqrt{(-1 -7)^2 + (3 - 4)^2}= \sqrt{65}[/tex]

[tex]OQ = \sqrt{(2 -7)^2 + (5 - 4)^2}= \sqrt{26}[/tex]

From the above computations, the longest side is PQ

So;

[tex]PQ^2 = OP^2 + OQ^2[/tex] --- Test of Pythagoras

[tex]\sqrt{65}^2 = \sqrt{13}^2 + \sqrt{26}^2[/tex]

[tex]65 = 13 + 26[/tex]

[tex]65 \ne 39[/tex]

The above points do not make a right triangle

[tex]3.\ T(1 , 1)\ U(3 , 3)\ V(5 , 1)[/tex]

Calculate distance

[tex]TU = \sqrt{(1 -3)^2 + (1 - 3)^2}= \sqrt{8} = 2\sqrt2[/tex]

[tex]UV = \sqrt{(3 -5)^2 + (1 - 3)^2}= \sqrt{8} = 2\sqrt2[/tex]

[tex]TV = \sqrt{(1 -5)^2 + (1 - 1)^2}= \sqrt{16} = 4[/tex]

From the above computations, the longest side is TV

So;

[tex]TV^2 = TU^2 + UV^2[/tex] --- Test of Pythagoras

[tex]4^2 = (2\sqrt 2)^2 +(2\sqrt 2)^2[/tex]

[tex]16 = 8 + 8[/tex]

[tex]16 = 16[/tex]

The above points not make a right triangle

Por lo tanto, debe considerarse a los habitantes de los Estados Unidos nacidos en Puerto Rico como ciudadanos americanos con la misma cantidad y calidad de derechos que todo otro ciudadano americano.

conclusion about tropical cyclones​

Answers

Explanation:

summary about tropical cyclone

A tropical cyclone corresponds to a center of low atmospheric pressure that results in strong storms and winds that can reach up to 118 km/h.

How are tropical cyclones formed?

They are formed from the meeting of hot and humid air from tropical regions that rises to the upper layers of the atmosphere, while the denser and colder air sinks to the surface.

In this way, there is an increase in heat that occurs due to the condensation of hot and humid air, generating the convection process and the formation of the cyclone.

Therefore, tropical cyclones can cause destruction of coastal areas and generate flooding and destruction of vegetation.

Based on observations he made with his naked eye, Ptolemy saw the Universe as a set of nested, transparent spheres, with Earth in the center. He posited that the Moon, Mercury, Venus, and the Sun all revolved around Earth.Nicolaus Copernicus was an astronomer who proposed a heliocentric system, that the planets orbit around the Sun; that Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow changes in the direction of this axis account for the precession of the equinoxes.Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science". ... He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects.(1) agricultural improvements that made possible the provision of food for a larger nonagricultural population, (2) economic changes that resulted in a wider distribution of wealth, the decline of land as a source of wealth in the face of rising industrial production, and increased international trade, (3) political changes reflecting the shift in economic power, as well as new state policies corresponding to the needs of an industrialized society.These are the first three industrial revolutions that transformed our modern society. With each of these three advancements—the steam engine, the age of science and mass production, and the rise of digital technology—the world around us fundamentally changed.
