At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is
∑ F = 450 N - (0.75 kg) g = (0.75 kg) a
where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of
a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²
Then its maximum tangential speed v is such that
a = v² / (1.0 m)
⇒ v = √((1.0 m) a) ≈ 25 m/s
The purpose of the Missouri Compromise was to keep a balance between the number of slave states and the number of free states in the Union. It allowed Missouri to enter as a slave state at the same time Maine entered as a free state, thus maintaining a balance in numbers of free and slave states.
The test organism ferments sucrose best under reduced oxygen conditions.
The sample was incubated less than 24 hours, which allowed for only limited fermentation.
The media was contaminated.
The organism is an obligate aerobe and therefore can only grow inside the Durham tube.
The media was prepared wrong.
The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
The test organism did not ferment sucrose.
1)The test organism ferments sucrose best under reduced oxygen conditions.
2)The sample was incubated less than 24 hours, which allowed for only limited fermentation.
3)The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
