Answer:
It cannot reach us by conduction or convection as there is no medium such as air in most part of the space between the earth and the sun. From the sun the heat comes to us by another process known as radiation. The transfer of heat by radiation does not require any medium.
<em>The correct option is</em> D. The initial momentum of the blue and green train combined during the collision is 200 kgm/s.
<h3>
Initial momentum of the blue and green train</h3>
Apply the principle of conservation of linear momentum as follows;
Pi = m1v1 + m2v2
where;
- m1 is mass of blue train
- m2 is mass of green train
- v1 is velocity of blue train
- v2 is velocity green train
- Pi is the initial momentum of the two trains
Pi = (50 x 4) + 30(0)
Pi = 200 kgm/s
Thus, the initial momentum of the blue and green train combined is 200 kgm/s.

None of the lenses on that list is a converting lens.
None are converging either.
Potassium iron magnesium aluminum silicate hydroxide and Potassium magnesium aluminum silicate hydroxide.
I would say the answer to your question is A Ferris wheel turning at a constant speed. The reasoning behind this answer is the fact that traveling in a constant direction at a constant speed is not accelerating. The Ferris wheel is the only option that fits this description. The last option would be incorrect due to independent causes such as speed limit changes as well as turns and stops on the highway.
