They would only know the width of the window. A floor plan is like a top down view of a building. Imagine that you cut your house in half horizontally, and then looked down at it. All you would see would be the width of the windows, not the height or anything else.
The hotter an object is, the more kinetic energy it has, but i'm not sure what is the exact word missing??
Solution :
Given :
Mass attached to the spring = 4 kg
Mass dropped = 6 kg
Force constant = 100 N/m
Initial amplitude = 2 m
Therefore,
a). 

= 10 m/s
Final velocity, v at equilibrium position, v = 5 m/s
Now, 
A' = amplitude = 1.4142 m
b). 
m' = 2m
Hence, 
c). 

Therefore, factor 
Thus, the energy will change half times as the result of the collision.
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
Answer:
algae
Explanation:
The Atlantic off the East Coast of the United States usually appears green. This is due to the presence of algae and plant life.
