4x In which situation is there NO work being done? A a car being pushed 100 m B a 25 N force applied over 6 meters C a mouse pushing a crumb across the floor D L a 10 N force applied to a stationary wall

In physics, work is defined as the transfer or conversion of energy in such a manner that the directional flow of energy moves or changes matter. The equation describes the calculation of work, where is work done, is the force applied, is the distance over which the force is applied and is the angle between the force and the direction of motion. Given this, work equals zero whenever the force or the distance is zero or the angle between force and direction of motion is 90 degrees.## Step 1: Analyze each choiceA) A car being pushed 100m - A car being pushed 100 meters implies a distance and a force, therefore according to the equation , work is being done.B) A 25 N force applied over 6 meters - Since there is a force being applied over a distance, work is being done.C) A mouse pushing a crumb across the floor - The mouse is applying a force to the crumb and the crumb is moving a certain distance. Therefore, work is being done.D) A 10 N force applied to a stationary wall - The wall is not moving so the actual distance moved by the wall is zero. Hence, the work done is zero.
