Using the expression(see reference):
W = Fd cos(θ)
where:
F is the Force = 80 N
d is the Displacement = 10 m
θ is the Angle = 0 rad (As the push is horizontal)
we calculate the value for Work done(W):
W = 80*10*Cos[0]
∴ W = 800.0 Joule

When a person pushes a crate across the floor what is the effect?
It goes across.
What happens when someone pushes a chair across the floor?
intertia takes place
If a race car travels along a raceway at a constant velocity of 200kmh what horizontal forces act?
The road is the horizontal force on the car. The tires push on the road which is the action and the road pushes forward on the tires which is the reaction.
When a person pushes a crate across the floor what force is working in reaction to the pushing force?
friction
What is a contact force between two boxes?
It is an external force that pushes on two boxes in contact on a horizontal surface. You can determine the acceleration of the boxes and the magnitude of the force between them.

What happens when someone pushes a chair across the room using newtons second law of motion?
The chair movement is dependent on its weight and the amount of force
Does a dome Mountain from when hardened magma is uplifted and pushes up a horizontal layer of rock?
No.
What is the different between a Igneous dike rock and a Igneous sill rock?
AnswerA dike is an intrusive body of magma that pushes its way across layers of sediments.A sill is an intrusive body of magma that pushes its way between layers of sediments.
