The diameter of hydrogen atom is about 1.04 times 10-10 meters. A protein molecule has an overall length 1000 times (1 times 10 to the third power) the diameter of hydrogen atom What is the length of the protein molecule in meters if we write it at in scientific notation
Suppose you are designing a proton decay experiment and you can detect 50 percent of the proton decays in a tank of water.How many cubic meters of water is this?
A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 km. 1 year = 3.156 ×× 107 s.   How many meters are there in 1.70 ly? Express your answer using three significant figures. Express in scientific notation!             1.70 ly = _________________m How many AU are there in 1.70 ly light-year? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________AU
