What Hadad can do is be determined or persistent in interconnecting with the doctor in numerous visits for the reason that sometimes a doctor doesn't see all the indications or a fundamental issue in the first visit. He must go see the doctor few times maybe there are a series of test to do to know what is happening to Hadad.
A standard for comparison that helps to ensure that the experimental result is caused by the condition being tested is the control.
<u>Explanation:</u>
In an experiment, we need to use a reference or standard term with which we compare our obtained results for better accuracy and precision. So there will several conditions or boundary conditions that need to include in those experiments to prevent the experiment from having a fallback or repair.
Among these several conditions, some of the conditions are mostly given to compare with the conditions occurred during the running of the experiment. And if any case, there is any change in those conditions with respect to standard conditions during the running of the experiment, then the experiment should be stopped.
So, these conditions which are standard comparison and helps to ensure that the experimental result is caused by the condition being tested and not anything else is termed as control.
Answer:
B. Marginal cost equals long-run average total cost.
Explanation:
The zero profit condition implies that entry continues until all firms are producing at minimum long run average total cost. Since the marginal cost curve cuts the long run average total cost curve at its minimum point, marginal cost and long run average total cost must be equal in long run equilibrium.
Answer:
Capillary Action.
Explanation:
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
Answer:
As the skydiver falls to the Earth, she experiences positive acceleration only due to gravity.
Explanation:
As the skydiver falls to the Earth, she experiences friction in the form of air resistance which tries to slow her down and is proportional to the her velocity. So it cannot have a positive acceleration as it acts in opposite direction to slow her down.
Inertia during skydiving is experienced when we open an parachute, the parachute slows down the speed of are descent hence changing our inertia of motion with a velocity.
Only the Earth's, gravitational field has an positive acceleration as it pulls us towards the Earth, hence increasing our velocity.
