Question

HELPPP !!! (20 points) , I’ll give you brainlist !!! here’s the question :
For his experiment,Julio compares how far different springs stretch he uses a centimeter ruler to measure the length of a spring . He attaches a weight to one end of the spring and measures its length again. He then measures the length of the spring with different-sized weights attached .

the graph below shows the results of Julio’s experiment .

Answer 1

Answer:

weight times spring length

Step-by-step explanation:

weight times spring length

Answer 2

Answer:

at w=0------Li =10

at w=10------L=15

L=Li+w×k---------(1)

k is constant of spring

go to (1) by using value of w , Li &L to calculat k

15 = 10+k×10

k=0.5

L=10+0.5*w
