can you help me in my

Experiment


Addition and Resolution of Vectors



Questions

1-
Compare the graphical and analytical (addition of components) methods for adding vectors.
Which is more accurate? Give possible sources of error for both methods. Why is it useful to use both methods?


What are the possible sources of error in the experimental method? (Why is it necessary to allow the strings to slip loosely about the ring**


**
If the weights of all the mass hangers were the same, could their weights have been neglected? Explain.***






What is the effect of the weight of the ring? What difference would it make if the ring were considerably more massive****


*****
do the thoritcal value of m3 and @3= angle 3 depend upon accelaration due to gravity g



thank you very mush

Hi sara! Welcome to PF! :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 
thank you tiny yes i am stuk :(


i nee for you help


how i can answer thi question
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
