P wave and S wave Seismic velocity

AI Thread Summary
To calculate the P wave velocity (VP) and S wave velocity (VS) in the mantle above the core-mantle boundary, the necessary velocities can be obtained directly from the provided diagram without needing to compute the elasticity modulus for bulk and shear. The diagram indicates the velocities on the horizontal axis (in km/s) and depth on the vertical axis (in km). It is suggested that the values can be read by inspection, simplifying the calculation process. Clarification on the specific values from the diagram is needed to confirm the results. The discussion emphasizes the importance of utilizing the diagram effectively to derive the required velocities.

Homework Statement


I need to calculate the P wave velocity (VP[mantle]) and S wave velocity (VS[mantle]) in the mantle just above the core-mantle boundary?

All the data is found in the diagram. I know the equation to find compressional wave (P waves) velocity but you need to find the elasticity modulus for bulk and shear, and apparently you don't need to find these there is a simpler way

Hi Caeser. I'm not sure what it is you need to calculate since the diagram provides the velocities by inspection. The horizontal axis is velocity (km/s). The vertical axis is depth (km). The mantle/core boundary is given.
 
did you find the answer?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
