Explain how conduction, convection, and radiation drive the water cycle in Earth’s system.

Answers

Answer:

During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.

Explanation:

Luck For You!

The process, in which conduction, convection, and radiation drive the water cycle in Earth’s system, is discussed in the answer.

What is water cycle?

The energy from the sun is what largely drives the water cycle. By evaporating water from the oceans, lakes, rivers, and even the soil, this solar energy powers the cycle. Through the process of transpiration, more water is transferred from plants to the atmosphere. Water droplets gradually acquire enough mass to fall back to Earth as precipitation as liquid water evaporates or transpires, forming clouds and water vapour.

The precipitation eventually transforms into runoff or groundwater and makes its way back into the surface reservoirs across a variety of periods. The hydrosphere currently contains the same amount of water as it has always contained in the Earth system since the water cycle is essentially a closed system.

Solar heat energy comes on earth's surface via radiation to the ponds, lakes, oceans, seas, rivers and other water resources and then the waterbodies get heated via conduction and evaporation happens. During evaporation time temperature water vapor goes to high altitude via convection of heat and cloud forms.

Answers

Answer:

Explanation:

Kinetic energy can be stored. For example, it takes work to lift a weight and place it on a shelf or to compress a spring. ... Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic. One example of an elastic collision would be one billiard ball striking another.

Please help!! The graph in the figure shows the position of a particle as it travels along the x-axis. What is the magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s?

Answers

The uniform movement allows to find the average speed, for which the correct answer is:

        B) 1.3 m / s

Kinematics studies the movement of bodies, establishing relationships between position, velocity and acceleration. In the special case that the acceleration is zero the motion is called uniform motion.

        v = [tex]\frac{\Delta x}{\Delta t}[/tex]

Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.

In this case

         v = [tex]\frac{2.0 - (-2.0)}{4.0\ -1.0}[/tex]

          v = 1.33 m / s

In conclusion using the uniform motion ratios we can find that the correct answer for the average velocity is

        B) 1.3 m / s

At t = 0s, Ball A is thrown straight up at m/s; Ball B is thrown at 16m/s 30.0° below the horizontal at 32 m/s. How do the magnitudes of the baseballs' accelerations32 2at t = 0s compare (do not neglect air resistance)?

Answers

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is  B

Explanation:

From the question we are told that

  The terminal  velocity of both balls is  [tex]v_t  =  32 \ m/s[/tex]

   The speed with which ball A is thrown up at t =0 s is  [tex]v__A}}  =  16\sqrt{2}[/tex]

   The speed with which ball B is thrown 30° below the horizontal  at t =0 s is  

[tex]v__{B}} =  32\sqrt{2}[/tex]

Generally the acceleration of ball A is (g i.e acceleration due gravity)given that it is thrown straight up  

Generally the vertical  acceleration of ball B is mathematically represented as

    [tex]a  = gcos (90 - 30)[/tex]

      [tex]a  = gcos (60)[/tex]

Generally the ratio of both acceleration is  

     [tex]\frac{a__{{A}}}{a__{{B}}}} =\frac{g}{gsin(60)}[/tex]

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{sin (60)}[/tex]

=>  [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{\frac{\sqrt{3} }{2} }[/tex]

=>[tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} }[/tex]

Rationalizing

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }[/tex]

=> [tex]\frac{a__{{A}}}{a__{{B}}}} = \frac{2 \sqrt{3} }{3}[/tex]

=>[tex]a__{B}} = \frac{2\sqrt{3} }{3} * a__{A}}[/tex]

What is magnetic energy?

Magnetic energy is defined as the shifting of the electrons' charge in various particles. Magnetism is the force that magnets employ to either attract or repel one another. Electric charges in motion are what generate magnetism.

Supposedly invisible or mysterious energy known as "animal magnetism" is claimed to affect people. Franz Mesmer, a German physician, used the term "animal magnetism," also known as mesmerism, to describe what he believed to be an innate natural power that all living things, including people, animals, and plants, had.

Two fish swimming in a river have the following equations of motion:

X 1 = - 6.4 m + (- 1.2 m/s) t

X 2 = 1.3 m + (- 2.7 m/s) t

Which fish is moving faster? ​

Answers

Answer:

The second fish, X2, is moving faster than the first fish, X1

Explanation:

The given parameters for the equation of motion of the fishes are;

X1 = -6.4 m + (-1.2 m/s)×t

X2 = 1.3 m + (-2.7 m/s)×t

The given equation are straight line equations in the slope and intercept form, where the slope is the speed and in m/s and the intercept is the starting point of swimming of the fishes

For the first fish, the intercept = -6.4 m, the slope = the  speed = -1.2 m/s

For the second fish, the intercept = 1.3 m, the slope = the  speed = -2.7 m/s

Whereby the fishes are swimming in the opposite direction of the measurement of length, we have;

The magnitude of the speed of the second fish [tex]\left | -2.7 \ m/s \right | = 2.7 \ m/s[/tex], is larger than the magnitude of the speed of the first fish [tex]\left | -1.2 \ m/s \right | = 1.2 \ m/s[/tex]

Therefore, the second fish, X2, is moving faster than the first fish, X1.
