How do we solve question 6, 9,25??

For question 9, you need to find the extension, in order to do that, you need to subtract the unloaded length from the length of the spring given (16.4-15=1.4) Then use the answer (1.4) which is the extension to find the load using the graph given
For question 25, use the equation for echo which is speed=(2*distance)/time. Substituting values would give you the distance which is 240m.

1.2N/2=0.6

wrong it's B, because 6 discs were removed and they weighed 1.8N so the answer is 1.8/6. Also it was clearly shown that there was a black carrier
