A spring that obeys Hooke's law has a spring force constant of 266 N/m. This spring is then stretched by 28.4 cm. (a) What is the magnitude of the force required to stretch the spring by this distance

75.544 N.

Explanation:

From Hooke's law,

Applying,

F = ke Equation 1

Where F = Force required to stretch the spring, k = force constant of the spring, e = extension.

From the question,

Given: k = 266 N/m, e = 28.4 cm = 0.284 m

Substitute these values into equation 1

F = 266(0.284)

F = 75.544 N.

Hence the force required to stretch the spring is 75.544 N

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
