1. The problem statement, all variables and given/known data At Earth's location, the intensity of sunlight is 1.5kW/m^2. if no energy escaped earth, by how much would Earth's mass increase in 1 day? 2. Relevant equations ΔE=Δmc^2+ΔKE Rearth=6.378x10^3 3. The attempt at a solution I know that the change in kinetic energy does not change, so that value can go to 0. But I'm not sure what exactly I'm supposed to start with. The answer is supposed to be 1.83x10^5kg/day. Any help would REALLY be appreciated.
