Question 8 The star Betelgeuse is about 520 light-years away, If the speed of light were twice its present value, how far away would Betelgeuse be? O 2080 ly O 560 ly O 260 ly O 1040 ly O 130 ly Question 9 Which of the following is the reason for an ocean of water under Europa's frozen surface? O Furopa had many icy comets crash into the surface bring water to the moon and melting the water as it fell into the core. O Furopa formed with an unusual amount of liquid water in the core and the coldness of space wasn't able to freeze it. O upiter's strong gravitational force is causing Europa to flex in its orbit, leading to an increase in internal heating O Europa's close proximity to Jupiter puts it into a gravitational tug-of-war with Jupiter's largest moon Ganymede. Question 10 How was Neptune discovered? O When a large comet broke up and hit the planet, the explosion was seen from Earth-based telescopes O From a large sky survey that identified the "blue-green" planet.

The Planck time is the unique interval of time that can be built out of G, c, and h. Some physicists think that time intervals shorter than the Planck time have no meaning. Using G = 6.7 x 10-11 kg-1 m3 s-2, c = 3 x 108 m s-1, and h = 6.6 x 10-34 kg m2 s-1, calculate the Planck time, in units of 10-43 s.
16. Today, astronomers can detect and measure stellar parallax for thousands of the nearest stars, providing us with direct evidence that Earth really does orbit the Sun. Moreover, these measurements allow us to calculate distances to these relatively nearby stars. If we hope to use parallax to measure distances to even more-distant stars, which of the following telescopes would be most useful?
