Select the correct answer from each drop-down menu.

tends to raise co2 levels in the atmosphere, but
to lower co2 levels in the atmosphere.

1st blank options
-carpooling instead of driving alone
-cutting down trees instead of growing trees
-reusing an item instead of buying new
-using energy-efficient cars instead of gas guzzlers

2nd blank options
-driving instead of walking
-releasing emissions instead of storing them
-using clean energy sources instead of fossil fuels

Cutting down trees instead of growing trees raises levels in the atmosphere, and Using clean energy sources instead of fossil fuels decreases the co2 levels in the atmosphere.

Explanation:

We know that the cutting down of tree and more use of fossil fuels increase the carbon dioxide in atmosphere and we can overcome it by using clean energy sources instead of fossil fuels.

no

sodium is solid at rt

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.
