Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the sun.
pogonyaev
Total mass of the Sun = 2x10^30kg 

<span>So 76% of that = (2x10^30kg)*(0.76) = 1.52x10^30kg ----> total amount of Hydrogen i</span><span>f only 12% of that is used for fusion, then (1.52x10^30kg)*(0.12) = 1.82x10^9kg</span>

What is the kinetic energy of a 1 kilogram ball is thrown into the air with an initial velocity of 30 m/sec
disa [49]
To find this we should use the equation Ek=1/2mv^2 where Ek is the kinetic energy, m is the mass and v is the velocity. So by this Ek=1/2*1*30^2 which then makes Ek=450 joules
