Question

The students obtained a value of 240 m/s for the speed of sound. The accepted value, in a science data book, is 343 m/s.

(i) Calculate the difference between the students' value and the accepted value as a percentage of the accepted value.​

Answer 1

Answer: 30.03%

Step-by-step explanation:

Step 1: Find the difference between the two values.

Difference = |Accepted Value - Students' Value|

Difference = |343 m/s - 240 m/s|

Difference = 103 m/s

Step 2: Divide the difference by the accepted value.

Percentage Difference = (Difference / Accepted Value) * 100

Percentage Difference = (103 m/s / 343 m/s) * 100

Step 3: Calculate the percentage.

Percentage Difference ≈ 30.03%

The difference between the students' value and the accepted value is approximately 30.03% of the accepted value.

Answer 2

The difference between the students' value and the accepted value is:

343 m/s - 240 m/s = 103 m/s

To calculate the difference as a percentage of the accepted value, we divide the difference by the accepted value and multiply by 100:

(103 m/s / 343 m/s) x 100% = 30%

Therefore, the difference between the students' value and the accepted value is 30% of the accepted value.
