<h3>What is the Hooke's law?</h3>
Hooke's law states that the extension of a given material is directly proportional to the force applied as log as the elastic limit is not exceeded. Thus we have to know that; F = Ke
F = force applied
K = force constant
e = extension
Using the graph;
K = F/e
F = 200N
e = 5 cm or 5 * 10^-2 m
K = 200N/ 5 * 10^-2 m
K = 4000 N/m
Now;
Work = 1/2Ke^2
Work = 0.5 * 4000 N/m * (5 * 10^-2 m)^2
Work = 5 J

D. March because it is just below the 1 million marker on the graph and it is the only one that low.
Well, in order to figure out the answer is to divide until you figure out how many miles they went per second. If it takes 5 seconds to reach 50 miles per hour it took 10 seconds per every 10 miles meaning each mile took 1 second. (Not actually possible but the answer) So, If it finished a 100 mile trip in 2 hours it took an hour for 50 miles. If it took 1 hour for 50 miles divide 60/50 which gets you 1.2 so it took 1.2 miles per minute meaning the car went 120 miles per hour I believe. I hope this helps :)
Main Answer:
Assume that the temperature rises by 9.9 F
Initial Temperatures will be C1, F1
Final temperatures will be C2, F1 + 9.9
The relation between celsius and fahrenheit temperature is as follows:
C = 5/9(F - 32)
Increase in temperature in celsius will be
C2 - C1 = F2 - F1
C2 - C1 = 5/9 ( F1 +9.9 -32) - 5/9 ( F1 -32)
C2 - C1 = 5/9 ( F1 +9.9 -32 - F1 +32)
C2 - C1 = 5/9 (9.9)
C2 - C1 = 5.5C

What is temperature?
Temperature is defined as the degree of coldness or hotness of an object or a substance. Generally, it is measured in various temperature scales. They are celsius, fahrenheit, kelvin.
