Using this principle, check whether the equation f = 2 II is dimensionally correct,
g
where f-frequency, l-length and g-acceleration due to gravity.

please answer this question immediately

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
