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 electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
