What is the period of oscillation of a pendulum that is. 5m long? . 26 s

1. 42 s

6. 28 s

13. 9 s

d) physical means can be used to separate the components of air.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

a 2,000 calorie based diet.

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.
