Question

The amount of extansion in an elastic spring has a direct variation to the weight that is hanged from it. If a weight 250 g produces an extension of 3.25 cm , then how much weight will produced in extension of 14.3 cm?

Answer 1

Since 250 g produces extension of=3.25 cm
1 cm extension is produced by weight of = 250/3.25=76.92 grams.
14.3 cm extension is produced by weight of = 76.92× 14.3= 1099.9

Answer 2

Answer:

1100

Step-by-step explanation:

(Using x1/ y1 = x2/ y2)

Now, By Substituting we get,

3.25/ 250 = 14.3 / y2

y = 14.3 x 250 / 3.25

= 1100/ 11

Therefore, the weight should be 1100 g.
