This topic is actually quite controversial, but the answer in this case would be C.
Just some food for thought, the 2nd law of thermodynamics entropy of the universe is always increasing, but that doesn't necessarily mean that earth's entropy has to. As long as the net change in entropy of the universe is increasing it doesn't matter if one planet is decreasing a nominal amount. Next, Earth as said is not a closed system and you could argue that the sunlight and energy from the sun is increasing the total energy within the system that is earth meaning that it is increasing in entropy. Next, if you consider increasing entropy as an increase in the number of possible permutations that the universe or parts of the universe can take, then it is completely possible that an ordered planet and life is possible, although rare. This theory explains why there are so many life forms and why entropy is actually increasing when divergent evolution occurs.

Best of luck, my man.
Answer:
0.9432 m/s
Explanation:
We are given;
Mass of swimmer;m_s = 64.38 kg
Mass of log; m_l = 237 kg
Velocity of swimmer; v_s = 3.472 m/s
Now, if we consider the first log and the swimmer as our system, then the force between the swimmer and the log and the log and the swimmer are internal forces. Thus, there are no external forces and therefore momentum must be conserved.
So;
Initial momentum = final momentum
m_l × v_l = m_s × v_s
Where v_l is speed of the log relative to water
Making v_l the subject, we have;
v_l = (m_s × v_s)/m_l
Plugging in the relevant values, we have;
v_l = (64.38 × 3.472)/237
v_l = 0.9432 m/s
<span>The equilibrant, also known as the counterbalancer in a force system, is an equal but opposite force that produces equilibrium. It acts against the resultant force to keep a body motionless. Suppose we have a 20kg mass on one end of a swing and nothing on the other. The swing will be titled unevenly because no force balances the 20kg weight. On the other hand suppose a weight of 40kg rest on the other end. This force doesn't produce equilibrium either because it isn't equal to the 20kg weight; the swing would tilt towards the weight of larger mass. A 20kg mass will balance the system. Hence the force which balances other forces, thus bringing an object to equilibrium is the equilbrant.</span>
