Suppose a galaxy is moving away from Earth at a speed of 0.78c. It emits radio waves of 0.680 m. What wavelength would we detect on Earth? with a wavelength
6. Consider a planet of mass m in orbit about a star of mass M. Since M >> m, we can assume the star is at rest. a) Show that the energy of the planet can be written as GMm E = 2mr? b) Now assume the planet is in a perfectly circular orbit. What is the energy in this case? c) Represent the energy obtained in part (b) on an energy diagram. (Draw and label very carefully.)
Suppose an alien race on a distant planet tries to send a message to us, with a laser (light). However, we were unaware that there is a stellar-mass black hole almost directly between us and them. How would this complicate our attempts to locate their position in the Galaxy? O Gravitational lensing would make the signal appear to be coming from a different location O The information carried by the laser (light) would be altered O It would not matter The black hole absorbs all of the light
Imagine that we had two electrons that were initially VERY far apart, moving towardeach other at nearly the speed of light, roughly 3 x 108 m/s. How close can they get to each other?
D Question 3 If a given mass undergoes a process in which that mass generates energy, what can we say about whether mass is conserved or not in light of E=mC²? O Mass is absolutely conserved because mass cannot be created or destroyed. O Mass is absolutely not conserved because an appreciable part is converted to energy. O We can assume that mass is conserved because the amount of mass converted to the energy is extremely small, and hence negligible O Mass is not conserved because a big part is converted to energy. O None of the above is reasonable.
Is it possible in principle for a human being who has a life expectancy of 70 years to make a round-trip journey to a part of the universe thousands of light-years distant? Explain.
