Answer:
A. Heat flowing from cold to hot
Explanation:
The second law of thermodynamics speaks about entropy and directions of processes. These directions go only in one direction, just as time moves only in one direction, as we know it. It is impossible to see time moving forward in a different sense. In the same way, the processes associated with heat transfer, go in a single direction this direction is associated with bodies at different temperatures. Where heat is transferred from a higher temperature body to a lower temperature body.
Heat transfer processes from a cold body to a hot body, do not exist and can not be achieved in a natural way.

An integrated circuit(IC) is a semiconductor water on which thousands of tiny resistors, transistors are fabricated.
Remember that an integrated circuit are the heart and brains of most circuits. They are the keystone of modern electronics.

If all the mass of fuel and oxygen is burned to form gases of combustion, the downward velocity of these gases would be 12,505 m/s.
<h3>
Conservation of linear momentum</h3>
The principle of conservation of linear momentum states that, the total momentum of an isolated system is constant.
The downward velocity of thes gases is calculated as follows;
v1(m1 + m2) = v2(m2)
305(1000 + 25) = v2(25)
312,625 = 25v2
v2 = 312,625/25
v2 = 12,505 m/s
Thus, If all the mass of fuel and oxygen is burned to form gases of combustion, the downward velocity of these gases would be 12,505 m/s.

The skeletal system is a body system comprised of bone structures and tissues that help hold the body up. It also gives the body its shape - as if it was the framework. On top of that, it protects internal organs within the body.
Therefore, the skeletal system is a body system comprised of bone structures and tissues that give the body its shape and protects internal organs.
Hope this helps!
