Abackpack weighs 8.2 newtons and has a mass of 5 kg on tje mion whatt is the strength of gravity on the moon

                                     Weight  =  (mass)  x  (local gravity)

                                        8.2 N  =  (5 kg)  x  ( g )

Divide each side  
by  5 kg :                  8.2 N / 5 kg  =                 g

                               g  =  (8.5 kg-m/s²)  /  (5 kg)

                                   =    (8.5 / 5)    m/s²

                                   =      1.7 m/s²  .

B, if it was a lower watt she could put it in for her normal time and not burn it
