A. 47.5 degrees B. 50.0 degrees C. 59.8 degrees D. 66.4 degrees E. 75.3 degrees
Why is there a 4-minute difference between the solar day and the sidereal day?
because the Earth's rotation is variable due to the pull of the Moon. because the Earth's axis is tilted by about 23 degrees. because the Earth is going around the Sun in the course of a year. because the stars slowly change their orientations in the galaxy.
Which of the following is not true of the special theory of relativity?
A) The special theory does not apply to situations that involve substantial acceleration or gravity; for that, you need the general theory of relativity. B) For low speeds, the theory predicts effects that are so small that they cannot be noticed without extremely precise, high-tech measurement. C) The theory is valid only at speeds close to the speed of light. D) The theory tells us that there is no such thing as absolute time or space, because measurements of time and space depend on your reference frame.
