The answer is A study of different surfaces to compare ability to repel water. Hope this helps!
Answer:
A) v = 1.885 m/s
B) v = 0.39 m/s
C) E = 0.03 J
D) 
Explanation:
Part A
We will use the conservation of energy to find the speed at equilibrium.
where 
and 
Therefore,
Part B
The conservation of energy will be used again.
where 
Therefore, v = 0.39 m/s.
Part C
Total energy of the system is equal to the potential energy at amplitude.
Part D
The general equation of motion in simple harmonic motion is
where 
is the phase angle to be determined by the initial conditions. In this case, the initial condition is that at t = 0, x is maximum. Therefore,
Answer:

Answer: Condensation of moisture in the air onto the glasses.
Explanation:
When you come from a cold environment into a warm ski lodge, the glasses are at a much lower temperature than that of the lodge.
Because the air in the room contains moisture (water vapor), it condenses on a surface whose temperature is lower than the dew point of the room.
