A girl of mass 40kg climbs a rope 8m long at a constant speed in 15s . WhT power does she expand against gravitational forces during the climbs ? I saw that the answer is 213.33
But the Dr. said it’s -213.33 according to ( final h- initial h)
So ... I don’t know what is the right answer
Plz help

8 meters above the spring

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
