The answer to your question is green
First off, you should be looking at the whole world, not just the northeastern US. Are other regions warming? Can you provide proof that simply because the northeast received a lot of snow and low temperatures, climate change is not a viable theory?
Answer:
13. c) Net
14. a) Gravity
15. d) Watt
16. b) the speed will suddenly decrease.
Explanation:
13. The <u>net </u> force is combination of all individual forces.
14. When we sit on the chair , then <u>gravitational force</u> acts on our body due to our mass.
F = mg
here, F = force due to gravity , g = acceleration due to gravity and m= mass of the body
15.Power : It is the force acting per unit area .It is discovered by James Watt

Its unit is
.In honor of the Scientist , its unit is Watt.
Watt = 
16. When the parachute first opens , the <u>speed of the skydiver suddenly decreases</u> because of the resistance offered by the air particles.(For more details look at the figure attached)
17. Transfer of momentum from one object to other is t<u>he law of conservation of momentum</u><u> </u>(NOT ENERGY).So the answer is<u> </u><u>False</u>
<u> Law of Conservation of Momentum : </u> Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
Alpha particles, also called alpha ray or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a <u>helium-4 nucleus. </u>They are generally produced in the process of alpha decay, but may also be produced in other ways.
