Want this question answered?
Work done equals force times distance, so 10.0 times 0.9 is 9 joules.
you will 'exert' a torque of (30*0.85)N.m at the hinges = 25.5N.m
When you stand on a floor, the force that you exert on the floor because of your weight is equal to the force with which the floor supports your weight.
a force of depend on mass
force x distance force=9800n distance=250m 9800 x 250= 2450000 Mega Joutes

10 J (novanet)
10 J (novanet)
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.

Because it's five times heavier of course !
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
When you stand on a floor, the force that you exert on the floor because of your weight is equal to the force with which the floor supports your weight.
a force of depend on mass
force x distance force=9800n distance=250m 9800 x 250= 2450000 Mega Joutes
Work = Force X Distance 20 N X 10 m = 200 N-m
How much force you can exert at one time.
