The heat of combustion of hydrogen (the energy released by burning hydrogen with oxygen) is 1.43�108j/kg. what mass of hydrogen would have to be burned in the sun in one second to release the same amount of energy (i. e., generate the same power) as is released by fusion?

the net reaction for the proton-proton chain is
411h \rightarrow24he + 2\beta+

to find the energy released by this reaction, you will need the following mass data:
mass of 11h=1.007825u and mass of 42he=4.002603u.

the total energy q released in a single fusion reaction event for the equation given in the problem introduction = 4.30�10? 12 j

the power radiated by the sun is about 4�1026w. the number of proton-proton chain fusion reactions in one second = 9.24�1037
mass of hydrogen converted into helium by the fusion reactions in one second = 6.20�1011 kg

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
