Help me if possible solve and snap a clear solution to me

Practical physics?? Ahn ahn!!

Yh, try na senior man

Physics practical is one of the easiest aspects of science subjects in sec schools. Just follow the instructions, dazall. Now, the readings are there, is it the graph of d1 against d0 that u can't plot? Or is it the slope, which is easier than drinking a glass of water? Or the mass of the ruler, which u can find from the formula provided and the values can be obtained from the graph?

The only thing I think will give u tough time is scale and the scale here is very easy. Depending on the size of graph paper, chose same scale for both vertical & horizontal axis (2 cm to 1 unit on both axes)

Precautions
Avoid parallax, allow the ruler to balance b4 taking readings, allow the Weight to balance without support etc

The slope and the mass of the rules, pls d formula to use and hint on solving them

From the values I'm seeing, u will end up with a straight line graph passing through the origin. I.e intercept =0
Hence, the equation is of the form; y=mx+c, and since c=0, u will arrive at y=mx.
Where m=slope
y=d1
x=d0
From here, u can find the mass of the ruler by substituting for the values stated in the formula.
Which formula are u talking about?
