1 GN Z11 is the most distant galaxy we have observed its distance from us is 9 8 Giga parsecs Giga 109 The parsec symbol pc is a unit of length used to measure large distances to astronomical objects outside the Solar System If 1 pc 3 26 light years ly and 1 ly 9 45x1015 m a How far is GN z11 in ly b How far is GN z11 in km 2 The size of protons have been measured to be about 1 fm A femtometer symbol fm is 10 15 meters Compare the distance to GN z11 above to the size of a proton HINT First convert the two measurements to the same units and then take the ratio between the two I am looking for an answer telling me only the order of magnitude difference powers of ten 3 You use about 3 x 108 kg m s 2 of energy every day How much is that in kWh kilowatt hour HINT look at the lecture slides for help but show
