For Figure A: 1. Complete the ray diagram to show the image formation.

2. In the diagram, u = 3. For the image obtained, u cm, object size= cm cm, image size... cm

4. Will the magnification obtained in this case be numerically equal to, less than or greater than unity?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

b. a lightning bug, plug of grass, and a worm
