Which of the following statements is correct?

it is 11 a. m. in the eastern time zone; therefore, it is 8 a. m.12 p. m.9 a. m. in the pacific time zone.

it is 3 p. m. in the central time zone; therefore, it is 4 p. m.2 p. m.1 p. m. in the mountain time zone.

it is 6 p. m. in the pacific time zone; therefore, it is 4 p. m.5 p. m.7 p. m. in hawaii.

it is 6 p. m. in hawaii; therefore, it is 10 p. m.9 p. m.11 p. m. in the eastern time zone.

it is 3 p. m. in hawaii; therefore, it is 6 p. m.7 p. m.5 p. m. in the mountain time zone.

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.
