Earth receives 1400 `W//m^(2)` of solar power. If all the solar energy falling on a lens of area `0.2m^(2)` is focussed onto a block of ice of mass 2.80g, it takes 110t(in sec) time to melt the ice. Value of t is:

Earth receives 1400 W//m^2 of solar power. If all the solar energy falling on a lens of area 0.2m^2 is focused on to a block of ice of mass 280 grams, the time taken to melt the ice will be….. Minutes. (Latent heat of fusion of ice= 3.3xx10^5J//kg)

If the solar energy received in 5 minutes by 10 m^2 area is 4200 kJ , find the value of solar constant.

If the solar constant is 1.4 kW//m^(2) , then the solar energy received by 1 m^(2) area in one hour is :
