How much power is required to do 100J of work on an object when a force of 10N pushes it a distance of 10m?

A force of 10 newtons acting through a distance of 10 meters does 100 joules of work.
Power is defined as the rate at which that work is done. So the power during the push is
(100) divided by (the number of seconds the push lasts).
Doing the job in less time indicates more power, just as you'd expect. But the total energy delivered
is still 100 joules, regardless of how slowly or quickly it's delivered.

What object can move with least force to move a distance of 5 meters?
There is no fundamental relationship between the distance an object moves and the force applied to it. Once an object is moving, no force is required to keep it moving, and the distance it can move without applied force is unlimited.
What force pushes an object forwards?
thrust
Is friction a push force?
Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.
What is necessary to keep objects moving in circular motions?
A centripetal force is required - something that pushes the object towards the center. This is in accordance with Newton's Second Law - to have an acceleration (which includes a change of velocity), a force is required.
When one object pushes or pulls another object the first object is what a force on the second object?
Pulling

If only gravity and support force acts on the object what is the net force?
The net force is the sum of all the forces acting on an object. Weight pulls down, buoyancy pushes up. If an object weighs 50 N and the buoyancy force is 40 N, only 10 N is required to lift the object out of the water

What is a ramp that decreases the force required to move an object while increasing the distance the object travels?
simple machine
I push a wall and it pushes back as long as I do - where does this infinite reaction force comes from?
The reaction force is not infinite; it is finite. For example, if you push with a force of 100N, the wall will push back with a force of 100N.If you are thinking that this requires an unlimited amount of energy, then you are confusing the concepts of force and energy. Energy is only required if the force is applied over a certain distance - the energy (or work) required to pull or push an object is equal to the force multiplied by the distance. In the example you give, the wall doesn't budge, so you have a force of 100 N times a distance of zero meters, equals an energy of 0 Joule.
Is the turning force required to turn or twist any object?
Answer:Obviously turning force is required to turn any object but to twist an object twisting force is required.
What is the reaction force to centripetal force in a centrifuge?
The centripetal force is the force with which the centrifuge pushes some object inwards. The opposite force, of course, is the object pushing the centrifuge outwards.
The force of a fluid that pushes an object up is called?
bouyancy or upthrust
Why do objects seldom move when forces are applied?
If the object doesn't move, that means there is an opposing force. In that case, the net force on the object is zero. Two typical cases are: * An object resting on a surface is pulled down by gravity. The surface pushes the object up. * In the case of a force that pulls or pushes sideways, the opposing force is usually friction.
