Answer:
The foam board has a larger gravitational force but it also has a very large air resistance force. The net (total) force on the foam board will give it a smaller acceleration than paper.
Explanation:
The air molecules get knocked away and take some of the kinetic energy away from the object, which makes the object slow down
Answer:

Answer:
There could be a few answers for this question, but my answer would be two different plants. Maybe a bush on the ground fighting for the energy of the sun with a tall tree. Leaves collect the energy from the sun and convert it to energy usable for the plant. a bush on the ground would be fighting for the sunlight with a tall tree.
Explanation:
(a) the sublimation of dry ice [conversion of CO2(s) directly to CO2(g)]
The balanced equation is given as;
CO2(s) --> CO2(g)
This reaction is endothermic, hence; Heat is a reactant and is needed to start the reaction.
(b) the reaction of 1 mol of sulfur dioxide with oxygen.
The balanced equation is given as;
2SO2 + O2 --> 2SO3
This reaction is exothermic, hence; Heat is a product and is given off by the reaction.
