Hi, if someone could help me figure this out I'd really appreciate it. Estimate the average power output of the Sun, given that about 1350 W/m^2 reaches the upper atmosphere of the Earth. I know the answer is 3.8 X 10^26 W but I don't know how to get there. I've tried different equations...

This question; A car takes 3s to acclelerate from to 0 to 50 km/h. Assuming constant power output from the engines and ignoring air resistance, how long does it take to go from o to 100 Km/h?, has been bothering me. I orginally assumed I could use the basic kinamatic equations but the power...

Hey everyone i was just wondering, for future reference, which type of fan generally yields the greatest output velocity/volumetric flowrate and a relatively low pressure drop (ie like +/- 10kpa sort of thing), assuming axial speed is the same for each of the general types of fans. This would be...
