Calculate the work done in lifting a 500-N barbell 2.2m above the floor what is the potential energy of the barbell when it is lifted to this height?
Work = Force x distance So since the barbell is 500N and the barbell travels 2.2 meters it becomes 500N x 2.2m = 1100 joules (N x m)
800 joules of work was done lifting a 200 newton box to a shelf directly above the box.?

What is The work done holding a 50 kg object at a height of 2 m above the floor for 10 seconds?
The answer is 0. If you used the formula of =>mgh, you would get a value which would be wrong. The question is a trick question. There is no work done in 'holding' an object but work would be done in 'lifting' an object. Hence, 0. ~Dartz

What is a smiley piercing?

What forms of energy are used when someone lifts a barbell to momentary muscular failure?
I don't know what you mean by momentary muscular failure. Surely if this happens he won't succeed in lifting the barbell? Lifting a barbell or indeed any muscular work done involves chemical changes in the muscles which provide the energy required, in this case raising the weight against the force of gravity. The energy used to lift a weight m kg a height of h meters is 9.81 x m x h joules.

If a weight lifter lifts a barbell and then sets it down is any work done?
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.
How long is a long tongue bar?
Each barbell is scaled to the size of the tongue to be pierced therefore there is no "actual size" barbell for tongues, this is why you need to have the piercing done by a professional body piercer who will scale and measure the tongue and place the correctly sized barbell into the piercing.
Can the tongue be pierced with a clear barbell?
Plastics are never used for the initial tongue piercing if the service is provided by and experienced professional body piercer. Plastics can be used once the swelling had gone down and the tongue is ready for it's step down barbell (usually about two weeks after the piercing has been done). Plastics cause a false sens of security and people tend to bite and flex the barbell, this alone can prolong the healing period. If you want it done right go with the metal barbell do your aftercare and once the swelling has eased you can go to a plastic barbell, but be warned that should you have issues the metal barbell should be put back in to the piercing.
