Correct Answers is A.
The machines gives us some mechanical advantage. This means the mechanical average makes the work output greater than the work input
Simple most example is a lever. The force applied is smaller and the output work is larger as compared to input.
Option B cannot be true, as there must be a force to get some work done.
Option C and D are inverse of what a machine is designed for. A small force can be exerted through a large distance to have a large force exerted through a small distance. Common Example of this principle is a screw opener.
Answer:
The focal length is 
The radius of curvature is 
Explanation:
From the question we are told that
The magnification of the mirror is 
The distance of the person from the mirror(the object distance ) is 
The negative sign shows that it is been placed in front of the mirror
Generally the magnification of the mirror is mathematically represented as
=> 
=> 
Generally from the lens equation we have that
=> 
=>
Generally the radius of curvature is mathematically represented as
=> 
=>
I believe the correct answer from the choices listed above is the first option. <span>A blimp flying around over the Super Bowl has both kinetic and potential energy. It initially posses potential energy then as it moves te said energy is converted to kinetic energy. Hope this answers the question.
