How much work is done by a person pushing a cart 20 meters with a force of 50n 8: an electric hoist does 500 joules of work lifting a box 2 meters, how much force does the hoist use if you push on a solid brick wall with a force of 100n how much work is done.

W = force x distance

50 N x 20 m = 1,000 joules

For the first answer.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

did anyone actually do this? like if anyone has submitted this i rly need .
