Lifting a weight to a height of 20 meters takes 20 seconds for one crane and 10 seconds for anotherIs there any difference in the amount of work done on the weight by each crane?PROVE WITH SOLUTION THANKS SIR!
you could try wax paperbut you really shouldnt be using so much glue that it soaks all the way through the fabric
There is a great fabric glue called No Sew Avail at craft stores and fabric stores.
there's no difference in the amount of work its because in this casethe work done is the change of potential energy of the weights their change in Potential Energy is the same (since they end up with the same height) soo, work done is the same ) work has nothing to do with time )
