Answer: MET(Metabolic equivalent of task) is the measurement technique that is based on the ratio of the energy that is being spend by an individual by any physical activity to the energy spent by individual sitting in quiet position.
This ration has some reference in which is ratio is measured.The energy being measured in the activity time of the person considers his/her relative mass at that time. This relative mass is compared in accordance with the oxygen amount of 3.5 ml per kg/min that is almost equal to energy of the person in the sitting position.
To solve this problem, we must simply use the concept of Total Energy transferred both in terms of work and heat. This is basically conjugated in the first law of thermodynamics.
If we take the heat absorbed as positive and the expelled as negative we have that the total work done in the heat engine is


For the case of the engine pumps the Energy absorbed is

In this way the ratio between the two would be

So it is reversible, because the state of efficiency of the body is totally efficient.
Answer:
It's really based on personal preference, but I believe that it does make your design look better.
Explanation:
Moreover, fillet can help you save some money on filament and eliminates sharp points or edges.
Answer: The answer to that is false.
Explanation: Trees are a natural plant that doesn't need any technical equipment to grow. If trees weren't a part of the 4 items, then I'm pretty sure that the answer would've been true.
