The seasons are caused by varying length of the day light time, which is a result of the tilt of earth's axis relative to the direction perpendicular to the ecliptic. a. the the varying angle at which the sun's rays strike earth, a result of the tilt of earth's axis relative to the direction perpendicular to the ccliptic. b. the changing sun-earth distance, which is a result of the ellipticity of earth's orbit. d. a and b

cancer risk hope this

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

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.
