Aball is slightly too large to fit through a hole in a flat plate. the drawing shows two arrangements of this situation. in arrangement i the ball is made from metal a and the plate from metal b. when both the ball and the plate are cooled by the same number of celsius degrees, the ball passes through the hole. in arrangement ii the ball is also made from metal a, but the plate is made from metal c. here, the ball passes through the hole when both the ball and the plate are heated by the same number of celsius degrees. rank the coefficients of linear thermal expansion of metals a, b, and c in descending order (largest first).

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

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.

not too sure thinking all accelerations are pointed down
