My guess for this one would be; 400 N

My reasoning would be; it starts at 0 on both X and Y, if you need to get to 1.00 meters thats 4/4. 1/4 of 1.00 is .25, and on .25 its on 100 so multiply it by 4 to make 1.00 and you get 400 N

Answer:

The needed force is 400 N.

Explanation:

We need to calculate the force for 1.00 m string

According to graph,

The force applied for stretch from 0.10 to 0.15 is 20 N.

0.10-0.15 = 0.05 m

So, the force applied is 20 N for 0.05 m.

For stretch 0.05 m = 20 N

For stretch 1 m = $\dfrac{20}{0.05}= 400\ N$

Hence, The needed force is 400 N.

Because the specific metals aren’t mentioned in this inquiry. The educational guesses that we can propose is that:
1. The hypothetical inquiry: There are existing metals for making pots that will cook food much faster.

2. The one-tailed alternative hypothesis: There are other metals for making pots that will cook food much faster than the other metals. 
3. The one-tailed null hypothesis: All metals that are used in making pots will cook food at an equal rate.
