Answer:
A
Explanation:
to simplify let's make it apart the denominator into three part
now let's simplify
so the answer is A
hope it helps
for any question comment me ❤❤
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.

R=√20²+40²+2.20.40 cos 50
R=55 N
R/sin β = F/sin α
55/sin 50 = 40/sin α
α = 33°
Those forces are exactly equal.
Gravity always works as a pair of <em>EQUAL</em> forces ... one in each direction
between two masses. Your weight on the Earth is exactly the same as
the Earth's weight on you.
