Answer: Layer's of the Sun.
Explanation:
The three words of the list correspond to the layers of the interior and atmosphere of the Sun.
This briefly tells you what every layer is:
Core: it is the central zone of the zone.
There is where the nuclear reactions (fusion) that transform hydrogen into helium and produce vast amounts of energy occur.
Radiation zone:
Is a very hot region in the interior of the sum where electromagnetic radiation is the mechanism of heat energy transference.
Convection zone
<span>It is the outermost layer of the interior of the Sun, which is less dense than the radiation zone and the main heat transference mechanism is convection.

Answer:
The total applied force on the trolley is 5 N toward the North.
Explanation:
In this problem, Ben is pushing the trolley to north and Gary is pushing it to south. So both the forces are acting 180° opposite to each other. As force is a vector quantity, the net force or total force acting on any object should be calculated by vector addition of number of forces along with their directions. So in this case, if we consider the force Ben is applying as F1 and the force Gary is applying as F2 on the trolley. Then the net or total force acting on the trolley will be . This is because, F1 and F2 are acting opposite to each other in direction.Thus, .
So the total force acting on the trolley is 5 N and it is toward the north direction.
