Which of the following could be considered a scientific statement?
pizza is the best food on earth.

ghosts are all around us.

ants live in colonies.

brown is an ugly color.

-- pizza -- "best" can't be measured

-- brown -- "ugly" can't be measured

So neither of these can be studied, and neither of the statements could be the result of a previous scientific study.

-- ghosts -- there has never been a single verifiable observation to support this statement.

So "ants" is the only statement left. It's supported by hundreds of years of observations, and can be observed by anyone who's interested

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.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
