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
Mechanical energy is being used when a person pushes heavy boxes across the floor. The person's muscles convert chemical energy into mechanical energy to move the boxes.
In a parallel circuit, each component has its own separate pathway for current flow. Therefore, the voltage across each component remains the same because the voltage source pushes the same amount of voltage through each pathway simultaneously.
The person's push creates a force that accelerates the crate. As long as the force overcomes friction, the crate will move across the floor.
The work done by the person on the box can be calculated using the formula: Work = Force x Distance. In this case, the person applies a force of 200N over a distance of 5 meters. Thus, the work done is 200N x 5m = 1000 Joules.
The energy being used is mechanical energy. When the person pushes the boxes, they are converting the chemical energy stored in their muscles into kinetic energy to move the boxes.
No.

Clouds move fast across the sky due to the wind. The wind pushes the clouds along, causing them to travel quickly.
When someone pushes a chair across the room using Newton's second law of motion, the chair accelerates in the direction of the force applied. This acceleration is directly proportional to the force applied and inversely proportional to the mass of the chair. As long as the force is greater than any opposing forces like friction, the chair will continue to accelerate in the direction of the push.
