C did the most effort, but A walked the longest, so a reasonable answer is that they all did the same amount of work, as B simply mediates.
Answer:
The metre is currently defined as the length of the path travelled by light in a vacuum in 1299 792 458 of a second. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km
Answer:
1.8L
Explanation:
Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.
So x is the volume at pressure 235
235x = 101(4.2)
x = 424.2/235 = 1.8
Because of the different speeds..
