The total mass of the Sun is about 2 x 1030 kg. of which about 76 % was hydrogen when the Sun formed. However, only about 14 % of this hydrogen ever becomes available for fusion in the core. The rest remains in layers of the Sun where the temperature is too low for fusion. Part A Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the Sun. Express your answer using two significant figures. m = kg Submit Request Answer Part B The Sun fuses about 600 billion kilograms of hydrogen each second. Based on your result from part A, calculate how long the Sun's initial supply of hydrogen can last. Give your answer in both seconds and years. Express your answer using two significant figures. t =

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
