When returning from sea, a green navigational buoy should be passed in and always kept on the port side of the vessel.
The correct answer is can be reversed with no net change in either system or surroundings
Reversibility is a property that expresses the possibility of making the physical processes run in the opposite direction, infinitely varying the conditions that cause them.
The concept of reversibility has great importance in thermodynamics (in the foundation of its second principle), since it is the only type of processes that use the least amount of energy possible; thus, reversibly, the physical processes give their greatest performance.
In practice, it is not possible to obtain a completely reversible evolution of a process, because for this to happen, it should take place in an infinitesimal way, and, therefore, take an infinite time to complete. However, in order to obtain the highest possible efficiency, motors, machines, etc., are designed in such a way that the processes carried out on them are extremely similar to reversible processes.
All of the above. Empathy shows maturity because you are able to do the first two things. Imagining someone else's situation and being able to sympathize with it even if you haven't been in the same situation is empathy.
The null hypothesis makes a claim about population parameter. A null hypothesis is a statement about the value of a population parameter. So the correct answer is (a).
An example of a null hypothesis is one that asserts that no statistical significance can be found in a collection of provided observations. A hypothesis is tested using sample data to determine how plausible it is. It is represented as H0 and is occasionally referred to as simply the "null." To determine if a theory regarding markets, investment methods, or economies is correct or wrong, quantitative analysts employ the null hypothesis, often known as the conjecture. The alternate theory contends that there is a distinction.
Therefore correct answer is (a).
