5. Convert the following as indicated in the bracket. (a) 2 m 50 cm 15 mm (cm) (kg) (b) 250 gm (c) 8 minutes 20 seconds (d) 780 kg 500 gm (seconds) (quintal) (An (e) 108 km/hr (m/s)​

the answer would be   dignified - apex

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

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.
