The work required to stretch the spring is 350J.
<h3>Hooke's Law</h3>
This law can be written by the formula: F=kx, where:
F= elastic force (N)
k= spring constant (N/m)
x= linear displacement (m)
<h3>Spring Work</h3>
For finding the spring work in J, you should apply the formula , where:
W= work (J)
k= spring constant (N/m)
x= difference between the linear displacements (m)
The question gives:
x=5 cm=0.05m requires a force of 1.4N
x=8 cm =0.08m
- Step 1 - First, you should find the spring constant from Hooke's law, for x=5 cm and F=1.4N.
- Step 2 - Now you can apply the formula for spring work.

Answer:
A. (2,-7)
Step-by-step explanation:
Using DESMOS, we graph the linear equations. We see below two lines intersecting. The solution to a system is always the point at which it intersects. The solution here is (2,-7). This is the first option or option A.
Answer: D // Jenna and Amy
Step-by-step explanation:
jordan's is bigger than amy's but smaller than jennas
fiona and wendy's cats are bigger than amy's but smaller than jordan's
inequality for size:
amy < fiona & wendy < jordan < jenna
bigger cats are faster & smaller cats are more obedient
jennas cat is fastest
amy's cat is most obedient
To get the answer to this question you would have to multiply these numbers.
The normal price appears to be 65.95 for 180.5 feet.
First we could divide 430.25 by 180.5
This divides out to become 2.39027778.
We would then multiply This by our normal price for 180.5 feet, which is 65.95.
This gives us 157.63882.
We would next need to take the 10 percent off. The easiest way to do this is to multiply our price by .90
This would give us 141.484938.
"A and B must be disjoint" is the one among the following choices given in the question that must be true for <span>P (A and B) = P (A) * P (B). The correct option among all the options that are given in the question is the fourth option or option "D". I hope that this is the answer that has come to your great help.</span>
