The Hubble constant, H0, is approximately 73 km/(s × Mpc). This value is given in mixed units because it uses both kilometers and megaparsecs, which both measure distance. Multiplying this value by the conversion factor (1 Mpc)/(3.086 × 1019 km) fixes this issue. What is the resulting value for the Hubble constant? Write your answer in scientific notation. Be sure to include simplified units.

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.
