Ac voltmeters and ammeters usually give rms readings.
Answer:
C. All muscle contractions after Sarah reaches fatigue (about an hour into her run)
Explanation:
At the start of the marathon race, the main source of Sarah's energy will be the Adenosine Triphosphate (ATP) that her muscle has stored. After the exhaustion of the ATP stored, which averagely will be about an hour into the race, the creatine phosphate (which will be converted to ATP) will be her major energy source. But due to the non functionality of the creatine phosphate that she produces, there will be muscle contractions which will affect her race. Therefore, Sarah will suffer muscle contractions after she reaches fatigue( about an hour into her run)
Answer:
When the tree is at rest, its leaves are also at rest. But when we bring the tree in motion by means of shaking it, due to the inertia of leaves they still tend to be in rest. Thus, force is acting on leaves vigorously with changing direction rapidly. This results in detaching of leaves from the tree.
Explanation:

atomic mass of carbon is C = 12 g/mol
atomic mass of hydrogen is H = 1 g/mol
now number of carbon atoms
Similarly the number of hydrogen atoms are
so Carbon atom and hydrogen atom must be in ratio of 10:30
so the ratio is 1:3
now the empirical formula is always in simplest form
