Ameta-analysis (anderson & bushman, 2001)
reported that the average correlation between time spent playing video games ( x)
and engaging in aggressive behavior ( y) in a set of 21
well-controlled experimental studies was 19. this correlation was judged to be
statistically significant. in your own words, what can you say about the nature
of the relationship?

15.3 cos 65 degrees trig

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.
