How much work is required to lift a 3.08 kg object from the bottom of a 10.3 m deep well?

For an object moved along a vertical line near Earth's surface, the work required is given by:
Work = m g Δh
Where m is the object's mass (3.08 kg in this case), g is the acceleration due to gravity near Earth's surface (9.81 m/s2) and Δh is the change in the object's height (10.3 m in this case).

How much force to lift 50 kilograms onto a shelf 3 meters high?
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

How does the pulley combination helps you do work?
It creates a mechanical advantage and reduces the force required to lift or move an object.
What is the amount of force required to lift an object against the force of gravity equal to?
The acceleration due to gravity (9.8 meters/sec.^2) * mass of object.
When you lift an object energy is transferred to the object which give the object?
Potential energy
Can a screw lift an object?
Yes

How to lift a child?
lift him/her by the bottom!
What occurs if the air moves faster above an object than below it?
Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight. The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.

If the coefficient of static friction is 0.3 how much more force is needed to lift the object than start it sliding?
for lifting the object there is no role of friction,but of air friction.since no info,. is given about it so air friction = 0.thereby for lifting we have mg = mass * 9.8 (the wight of the object). and for sliding we have 0.3*mg . therefore 0.7mg of more force is required to lift it.
