If antonia exerts a force of 700 n to walk 6 m up a flight of stairs in 6s how much power does she use?

Work done = (potential energy gained) = (weight x height)

Work done = 700N x 6m

Work done = 4200 Newton-meters

Power = (work done) / (time to do the work)

Power = (4200 Newton-meters) / (6 sec)

Power = (4200/6) (Joules/sec)

Power = 700 watts

700 watts = 0.938 Horsepower Go Antonia !

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
