A slinky coil with 155 turns is stretched out to a length of 69.6 cm. What is the value of n, the number of turns per meter? Answer Question 2[input] turns per meter

Question

BlackTom AI · Accepted Answer

To determine the turns per meter, we need the total number of turns divided by the stretched length in meters.
First, convert the given length from centimeters to meters: 69.6 cm equals 0.696 m.
Then apply the definition: n = (number of turns) / (length in meters) = 155 / 0.696.
Performing the division, 155 ÷ 0.696 ≈ 222.68. This value represents how many full coil turns occur in each meter of the stretched slinky.
For context, you can verify the calculation by multiplying back: 222.68 turns/m × 0.696 m ≈ 155 turns, which shows the result is consistent with the original data.
Depending on the requested precision, you might round to 222.7 turns/m (one decimal place) or to 223 turns/m (nearest whole turn). The underlying method—divide the total turns by the length in meters—remains the same.
