Correct answer only !

a mountain climber exerts 41,000 j of work to climb a cliff. how much power does the climber need if she wants to finish in only 500 seconds? power = work / time

Power = work / time

So the work here is given as 41,000 J

and the time is 500 s

So...

Power = 41,000 / 500

Power = 82 W

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

does anyone know or what?
