Answer:
Explanation:
The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength...
In order to find which rational number is between 0 and 1, let's convert them into their decimal form:

Looking at the numbers in their decimal form, we can see that the number between 0 and 1 is one-fourth, therefore the correct option is the second one.
Answer:
The original dimensions of the building is 95 ft × 38 ft.
Explanation:
Let the original length be 'l' and original width be 'w'.
Given:
Original length (l) = 
Original width = 'w'.
So, 
Now, as per question:
Length and width is increased by 7 ft.
So, new length (l') = 
New width (w') = 
New perimeter (P) = 266 ft
Perimeter is given as:

Therefore, original width = 38 ft.
Original length is, 
Hence, the original dimensions of the building is 95 ft × 38 ft.
Answer:Downward
Explanation:
As elevator is moving upward but is decelerating to stop at top
Suppose mg is the weight of man
N is the normal reaction
a is the acceleration

here upward direction is positive while downward direction is negative
Therefore net force is in downward direction
