The convection currents in the student’s model different from the convection currents in Earth’s atmosphere and oceans, The sun. Because heats is obtained from the sun, is transferred to the Earth's atmosphere and seas.
<h3 /><h3>What is an experiment?</h3>
An experiment is a technique used to prove or disprove a theory, or to test the efficacy or probability of something that has never been done before.
The burner underneath the kettle is the source of heat in this experiment. On Earth, however, this is not the case since the source of heat is the Sun, which heats us from above rather than below.
Convection currents continue to flow in the same direction because when the sun heats air particles on the Earth's surface,
They ascend, but cool as they continue to climb. This causes them to descend, where they are heated up once more.
Hence,heats is obtained from the sun, is transferred to the Earth's atmosphere and seas.

<h2>Answer</h2>
25 miles/hour
<h2>Explanation</h2>
Given that,
<em>A pilot can travel with wind = 416miles </em>
<em>A pilot can travel against wind = 336miles</em>
<em>A pilot can speed without wind = 235miles/hour </em>
<em />
<em />
let wind speed = v miles/hr
pilot's speed with the wind = 235<em>+ v</em>
pilot's speed against the wind = 235 - v
<h2>
Time = distance / speed</h2>
416 / (235 + v) = 336 / (235 - v)
416(235 - v) = 336(235+v)
97760 - 416v = 78960 + 336v
97760 - 78960 = 416v + 336v
18800 = 752v
v = 18800/752
v = 25 miles/hour
wind speed = 25 mph
The water behind a hydroelectric dam stores gravitational potential energy since it is at a higher level than the water on the other side of the dam. As the water falls, this potential energy is converted into kinetic energy, which turns turbines to generate electricity. Often, the water comes from behind a dam built across a river valley. The water high up behind the dam contains gravitational potential energy . This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators , which may be built inside the dam.
Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation.
To solve this problem we will use the concepts related to the electromagnetic force related to the bases founded by Coulumb, the mathematical expression is the following as a function of force per unit area:
Here,
F = Force
L = Length
k = Coulomb constant
I =Each current
d = Distance
Force of the wire one which is located along the line y to 0.47m is then we have
Considering the B is zero at
Therefore the value of y for the line in the plane of the two wires along which the total B is zero is 0.25m
