Malik formed a hypothesis that an increase in atmospheric oxygen levels by 10% would cause red-legged grasshoppers to grow large
r than normal. Suppose that Malik performs an experiment to test his hypothesis. Which of these actions would represent a scientific mistake in his experiment? He experiments on live grasshoppers instead of preserved ones.
He focuses on red-legged grasshoppers instead of all kinds of grasshoppers.
He varies the nitrogen and carbon dioxide levels in the air from one trial to the next.
He conducts the experiment in a controlled lab setting with a lab partner.
He measures the mass and length of his specimens at the start of each trial.
This depends on the direction of the velocity vector to the magnetic field vector. The force is F=q(VxB) ("x" is the cross product.) The max force is when V and B are perpendicular. Then F=qVB = (1.602e-19)(2000)(300) = 9.612e-14 N
At 10 m/s, it will take (2 m)/(10 m/s) = 0.2 s to bridge the gap.
_____ However, it will take an additional 0.514 seconds (0.714 s total) for the policeman to land on the building below. The answer depends on the meaning of the question.
