The earth, the sun, and the seven other planets that are in orbit around the sun are part of a. a constellation. b. a solar system. c. a black hole. d. a star cluster.

B. A solar system

Explanation:

A solar system is a system consisting of a sun and the planets orbiting around the stars.

In our case, the star at the centre of the system is the Sun, while the Earth and all the other seven planets orbit around the Sun. The planets of our solar system are, in order from the closest to the farthest from the Sun:

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Neptune

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.
