3. What will happen if:
a. the object travels closer to the speed of light?
b. the object travels at the speed of light?
c. the object travels faster than the speed of light?
Speed = distance / time.
The letter "c" is used to represent the speed of light.
c = d / t
Assuming that the difference in the light travel time between the two dates was 7.6 minutes and that 1.00 AU = 150,000,000 km determine the speed of light.
a. 299,000,000 km/s
b. 299,000,000 m/s
c. 299,000 AU/minute
d. 299 AU/s
1. A rocket flies toward the earth at c, and the captain shines a
laser light beam in the forward direction. Which of the follow-
ing statements about the speed of this light are correct? (There
may be more than one correct answer.)
A. The captain measures speed c for the light.
B. An observer on earth measures speed e for the light.
C. An observer on earth measures speed c for the light.
D. The captain measures speed c for the light.

- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardWhen Sedna was discovered in 2003, it was the most distant object known to orbit the Sun. Currently, it is moving toward the inner solar system. Its period is 10,500 years. Its perihelion distance is 75 AU. a. What is its semimajor axis in astronomical units? b. What is its aphelion distance?arrow_forwardWhat, on a sphere, is analogous to a two-dimensional Cartesian coordinate system?arrow_forward
