Question

2 The table shows the results of an experiment. Determine the value of X. Trial 3 X Amplitude /m Trial 1 0.217 Trial 2 0.247 Trial 4 0.223 Mean 0.224

Answer 1

To find the value of x, we need to determine the amplitude for trial 3.

The table shows that the amplitude for trial 1 is 0.217, for trial 2 is 0.247, for trial 4 is 0.223, and the mean amplitude is 0.224.

Since the mean amplitude is calculated by finding the average of the amplitudes for all trials, we can use this value to determine the amplitude for trial 3.

If we assume that the amplitudes for all trials are evenly distributed, we can subtract the amplitudes for trial 1, 2, and 4 from the mean amplitude and divide the result by the number of trials (which is 4) to find the amplitude for trial 3.

Mean amplitude - Amplitude for trial 1 - Amplitude for trial 2 - Amplitude for trial 4 = Amplitude for trial 3

0.224 - 0.217 - 0.247 - 0.223 = Amplitude for trial 3

0.224 - 0.687 = Amplitude for trial 3

-0.463 = Amplitude for trial 3

Therefore, the value of x, which represents the amplitude for trial 3, is approximately -0.463 meters.
