I'm in my physics course right now and recently became interested in mineral deposits and my teacher told me to look into how geologists use the wave nature of light to find mineral deposists.. I am not sure if I am just really confused about the subject or if I just can't find anything but...

Homework Statement A mass of 5 kg is suspended by two strings, 24 cm and 32 cm long, from two points that are 40 cm apart and at the same level. Determine the tension in each of the strings. Would the 40 cm length be the resultant or do you rearrange the 24 and 32 as head to tail...

Can anyone help me understand mass spectrometers? Their separation and analyzing techniques? This isn't a homework question, I just am curious and want to know. thanks

But I don't understand what the experimental errors are... how could string have affected it in any way?

Homework Statement String that is equal in length to the string connecting the pulley is sometimes tied to the bottoms of the two masses, where it hangs suspended between them. Explain why this would reduce experimental errors. Homework Equations The Attempt at a Solution I'm...

calculating percent error in a lab please help! Homework Statement I have to calculate an experimental value for g using values from my lab. I got -45.9 as my value, and now i have to calculate the percent error Homework Equations a= g (m2 - m1/ m2+m1) was the equation i used...
