If the sun revolves around the galactic center with a period of 200 million years and the distance of the sun from the galactic center is 30,000 light-years, determine the mass of our galaxy. 6 x 10^24 kg 2 x 10^30 kg 3 x 10^41 kg 5 x 10^72 kg Which observation confirms the idea that the Moon is primarily responsible for the tides? high tides are strong at full moon high tides occur about one hour later every day, and the Moon rises about one hour later every day high tides are strong at new moon all of the above none of the above Equivalence Principle- Picture with albert Einstein A 1 kg mass is moved horizontally with a force of 10 N on a surface where there is no friction. Calculate the acceleration. 1 m/ s 2 10 m/s 2 0.1 m/s 2 0 If the centripetal acceleration of the Moon toward the earth is 0.0027 m/sec 2 , determine the force by which Earth attracts the Moon. 10 20 newton 2 x 10 20 newton 2 x 10 14 newton 7.25 x 10 23 newton Suppose the earth was twice as large in size but its mass was the same. What would happen to the value of acceleration due to gravity compared to g? remain the same (g) 2g g/2 g/4 4g
