Assuming the gravitylight outputs 1w, find the velocity of a 12kg weight powering the device. clearly state any otherassumptions used to carry out the analysis. b)if the gravitylight operates for 30 minutesat the power level in part a), what length of chainmust be used. is this reasonable? c)according to their website, the gravitylightfunctions withweights around 10kgat heights ofaround 2 meters. find the maximum power the device can produceif it operates for 20 minutes. compare this to the power consumption of other lighting
