Answer:
W1 = W2 = 50k Joules (assuming W1 and W2 have the same force constant, k)
W1 - W2 = 0
Step-by-step explanation:
Work done in stretching a spring is given by 1/2ke^2
Where, k is force constant and e is extension
e1 = 30cm - 20cm = 10cm
W1 = 1/2k(e1)^2 = 1/2×k×10^2 = 50k Joules
e2 = 40cm - 30cm = 10cm
W2 = 1/2k(e2)^2 = 1/2×k×10^2 = 50k Joules
W1 = W2 = 50k Joules provided W1 and W2 have equal force constant
Therefore, W1 - W2 = 0
For Part A: You would put a dot on -8 on your line graph, and also put a dot on 13 as well. This is representing the temperatures of White Plains, NY.
For part B: The answer would be 21 degrees warmer.
Hope this helps!

Answer:
x= -5
Step-by-step explanation:
f(x) = [ x^2 - 25 ] / [ x + 5 ] = [ (x + 5) ( x- 5)] / [ x + 5 ] = x - 5
This will be the graph of f(x) = x - 5 with a "hole" at x = - 5
Answer:
56.25
Step-by-step explanation:
Hello!
To complete the square
- we take the b-value
- Divide it by 2
- And square it
<h3>Complete the square:</h3>
We add 56.25 to both sides.
