Question:
The earth receives 1.8 1014 kJ/s of solar energy. What mass of solar material is converted to energy over a 24 h period to provide the daily amount of solar energy to the earth?
I believe you have to use E = MC^2 but am not sure how to get the units right (i need answer in kg)
Answer:
Yes, you would use E = mc^2.
E = energy = 1.81014 kj
m = mass = unknown
c = speed of light = 3.00 x 10^8 m/s
Use E = mc^2 to calculate mass per second. This will give you the mass in kg. Then multiply this answer by the number of seconds in one hour (3600) and multiply that answer by the number of hours in one day (24)
