Answer:
W₂ is three times W₁ (W₂ = 3W₁)
Step-by-step explanation:
Applying,
W = ke²/2............. Equation 1
Where W = workdone in stretching the spring, k = spring constant, e = extension.
For W₁,
W₁ = ke₁²/2
Given: e₁ = 30-20 = 10 cm = 0.1 m
Substitute these value into equation 1
W₁ = k(0.1²)/2
W₁ = 0.005k Joules
For W₂,
W₂ = (ke/2)-W₁
Given: e = (40-20) = 20 cm = 0.1 m
Substitute these value into equation 1
W₂ = (k×0.2²/2)-0.005
W₂ = 0.015k Joules.
W₂/W₁ = 0.015k/0.005k
W₂/W₁ = 3
Therefore,
W₂ = 3W₁

<u>Area Of Compound Regions</u>
When a surface has no regular shape, it can be usually divided into smaller regular parts and add their areas. The surface shown in the figure can be split into 3 smaller rectangles (please refer to the image below).
The area of the yellow part is
The pink region has a height h=4 yd - 3 yd = 1 yd
The area of the pink region is
The total area is
Answer:
Step-by-step explanation:
If the equation of height of a man is modeled by the function y = 1.6x + 48 where;
y is the height of a man
x is the shoe size
To get the approximate shoe size for a man having a height of 60 inches, we will substitute y = 60 into the formula ans solve for x as shoen;
y = 1.6x + 48
60 = 1.6x + 48
1.6x = 60-48
1.6x = 12
x = 60/1.6
x = 7.5
x = 7 1/2
Hence the approximate shoe size for a man having a height of 60 inches is 7 1/2
