Studies of the relationship of the sun to our Galaxy- The Milky Way - Have revealed that the sun is located near the outer edge of the galatic disc, about 30,000 (Ly) (1Ly= 9.46X1015m) from the center. The sun has an orbital speed of aproximately 250 km/s around the galactic center.
(a) what is the period of the sun's galactic motion?
(b) what is the order of magnitude of the mass of the milky way galaxy?
(c) Suppose the galaxy is made mostly of stars of which the sun is typical. What is the order of magnitude of the number of stars in the Milky Way?
You can turn the crank at a maximum rate of 3 turns per second, but hand crank is connected to the coil through a set of gears that makes the coil spin at a rate 6 times larger than the rate at which you turn the crank. What is the maximum emf you ca..
