Answer:
Boyle's Law simply describes the relationship between the pressure and volume of an enclosed gas when Temperature remains constant. Tripling the pressure will reduce its volume to 1/3, and so on. Alternatively, if you double the volume available to an enclosed gas, pressure is halved.
Explanation:
Answer:
They both work together in order to create a good experience for the passenger, but I think that the answer is changing acceleration because when the rollercoaster changes acceleration it gives it speed.

I really hope this helps.
Answer:
The volume of the extra water is 
Solution:
As per the question:
Mass of the canoe, 
Height of the canoe, h = 21.5 ft
Mass of the kevlar canoe, 
Now, we know that, bouyant force equals the weight of the fluid displaced:
Now,

(1)
where
V = volume
= density
m = mass
Now, for the canoe,
Using eqn (1):


Similarly, for Kevlar canoe:

Now, for the excess volume:
V = 
V = 
Answer:
Explanation:
30 we know that radius is 18 and the circumference is 36pi and the time to go around is is 36pi/30=1.2pi≈3.76991118
