Process of Science: Devise an experiment you could conduct (using any technology you can dream up—it doesn't have to already exist) to test a prediction of special relativity
What will be an ideal response?
Many are possible. One may be to test the twin paradox by sending an astronaut away for a long time at relativistic speeds to observe their aging compared to those remaining on Earth.

All three circuits below have R = 100 ?, C = 1.0 mF, and emf ? = (5.0 V) sin (377 t). The inductors in (B) and (C) are placed sufficiently far apart so that they do not alter one another's inductance. Such inductors add combine like resistors. Which statement regarding the angular resonance frequencies ?A, ?B, and ?C is correct?

In general, when we compare the mass of a galaxy or cluster of galaxies to the amount of light it emits (that is, when we look at it mass-to-light ratio), we expect that
A) the higher amount of mass relative to light (higher mass-to-light ratio), the lower the proportion of dark matter. B) the higher the amount of mass relative to light (higher mass-to-light ratio), the greater the proportion of dark matter. C) the amount of light should be at least one solar luminosity for each solar mass of matter (mass-to-light ratio less than or equal to 1). D) the higher the amount of mass relative to light (higher mass-to-light ratio), the older the galaxy or cluster.
A solid sphere, solid cylinder, and a hollow pipe all have equal masses and radii. If the three are released simultaneously at the top of an inclined plane, and roll without slipping which will reach the bottom first?
A) sphere B) pipe C) cylinder D) they all reach bottom in the same time E) It depends on the angle of inclination.
