In Fizeau's experiment to measure the speed of light, the wheel has 475 notches and rotates with a speed of 40.0 rev/sec. Light passing through one notch travels to the mirror and back just in time to pass through the next notch
If the distance between the wheel and the mirror is 7890 m, what is the speed of light measured by this experiment? A) 3.00 × 108 m/s
B) 3.00 × 10-8 m/s
C) 3.22 × 108 m/s
D) 3.22 × 10-8 m/s
E) 2.25 × 108 m/s

A 10-N block and a 1-N block lie on a horizontal frictionless table. To impart equal horizontal accelerations, we would have to push the heavier block with
A) an equal force. B) 10 times as much force. C) 10 squared or 100 times as much force. D) 1/10 as much force. E) none of the above
According to our theory of solar system formation, why did Uranus and Neptune end up to be much less massive than Jupiter and Saturn?
A) The colder gas in the outer regions of the solar nebula had less gravity and therefore could not gather up into such large balls as it could closer in. B) Ices were able to condense at the distance of Jupiter and Saturn, but only rock and metal could condense at the distances of Uranus and Neptune. C) Particles in the solar nebula were more spread out at greater distances, so that accretion took longer and there was less time to pull in gas before the solar wind cleared the nebula. D) The size differences are thought to be a random coincidence.
An F-type star would have a larger habitable zone than does our Sun
