Mathematics · Linear Equations
An object hangs from a spring. The formula l = 30 + 2w relates the length l, in centimeters, of the spring to the weight w, in newtons, of the object. Which of the following describes the meaning of the 2 in this context?
- 1The increase in the length, in centimeters, of the spring for each one-newton increase in the weight of the object✓
- 2The increase in the weight, in newtons, of the object for each one-centimeter increase in the length of the spring
- 3The weight, in newtons, of an object that will stretch the spring 30 centimeters
- 4The length, in centimeters, of the spring with no weight attached
Correct answer
The increase in the length, in centimeters, of the spring for each one-newton increase in the weight of the object
