The Hubble Law, can be used to determine the age of the universe. Using your average value of H0, calculate the recessional velocity of a galaxy which is 800 Mpc away. Velocity of a galaxy 800 Mpc away (Vgalaxy.):.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
