Show that the statement in the text is correct: namely, that roughly 600 million tons of hydrogen must be converted to helium in the sun each second to explain its energy output. (hint: recall einstein’s most famous formula, and remember that for each kg of hydrogen, 0.0071 kg of mass is converted into energy.) how long will it be before 10% of the hydrogen is converted into helium? does this answer agree with the lifetime you calculated in exercise 16.35?

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
