A. Use the definition of the center of mass to determine the maximum “wobble” velocity of a star of mass M caused by a planet of mass m orbiting at a distance r from the star with a period T. B. Thanks to Kepler, we know that the mass, period, and distance of an orbiting object are actually related. Use Newton’s version of Kepler’s Third Law to determine the maximum “wobble” velocity in terms of M, m, and r.

Express your answer in kilometers per second to three significant figures .Part B Determine the mass M of each star. Express your answer in kilograms to one significant figure.1. Please help me answer A and B. Well explained please. A. Sets out the two postulates of Albert Einstein's theory of special relativity B. What is simultaneity? Use a concrete example in your explanation.
- Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 kmkm (or even higher) above the surface. Io has a mass of 8.93×1022kg8.93×1022kg and a radius of 1821 kmkm. Part A How high would this material go on earth if it were ejected with the same speed as on Io? (RERE = 6370 kmkm, mE=5.96×1024kgmE=5.96×1024kg) Express your answer with the appropriate units.Two objects, m1 and m2 are gravitationally attracted to one another. However, m1 is 500 times more massive than m2. Which mass experiences the greater gravitational attractive pull force? A) mass m1 experiences a greater attractive force from m2 B) mass m2 experiences a greater attractive force from m1 C) both masses experience equal but opposite attractive forces D) the problem statement does not provide enough information to be solved1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to the earth. You may assume that both clocks can measure time accurately to many significant digits. a. Will the two clocks still be synchronized after one year? Explain your reasoning. b. Imagine that the speed of light was much slower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning, using a calculation.
- You are given two point-like objects, known as M1 & M2. M1 has four times the mass of M2 and they are placed at a distance of d apart from each other. A. Can you sketch (in 2-dimensions) the gravitational field lines that are present in the region of space around the two masses. Show the direction of the field on the field lines. B. Explain quantitatively where you should place a test particle such that it experiences a net gravitational force of zero from the two point-like objects. Indicated this position on your diagram.A space probe with a diameter of 2.50m is moving past Saturn's moon Enceladus.

The nearest star (other than the sun) is Alpha Centauri. It is 4.34 light-years from Earth. How far is that in kilometers?c.

- Recently, astronomers have observed stars and other objects that orbit the center of the Milky Way Galaxy farther out than our Sun, but move around faster than we do. How do astronomers think such an observation can be explained? A, all these faster-moving objects must be escaping from the gravity of the Milky Way and will soon be lost to our Galaxy B. each of the faster-moving outer objects must be the result of a supernova explosion (giving them extra speed) C, it is the Sun that is moving too slowly because of a collision billions of years ago; the outer objects are really moving at the appropriate speed for their distance from the center D there must be a great deal of invisible dark matter outside the orbit of the Sun whose gravitational pull explains the faster motions we see out there E. no one can come up with any explanation for this puzzling observationplease explain why the graph is this way!In a spiral galaxy, the orbital speeds of stars far from the galaxy's center distance from the center increases. as the A. increase B. decrease C. are approximately the same D. The answer changes depending on the galaxy.
