So I received a lab today for physics. The first part of the lab I finished in about 20 minutes,had no trouble with it, but I don't understand what I'm doing wrong in the second part. I have to find the density of steel in excel, using experimental data that we found in class a few weeks ago.
The diameter, mass, and volume of the sphere are correct. This is my data:
Diameter Mass Volume
3.97 0.36 8.31
6.2 1.04 12.98
9.4 3.52 19.68
12.5 8.35 26.17
13.45 10.02 28.16
15.67 16.3 32.80
But for the density I keep getting these numbers:
Density
0.043318519
0.080131498
0.178886028
0.31910828
0.35588284
0.49691284
The balls are made of steel, so obviously the density I found is incorrect. Can someone please tell me what I'm doing wrong. I know the density is mass/volume... I know that, so I don't know what I'm doing wrong.
I'm sorry that the density and stuff are messed up, I don't know why physics forum did so
