Can the planet core produce S waves?

Click For Summary
S waves can only travel through solid materials, indicating that if they are observed from a quake on the far side of a planet, the planet's core must be solid. This conclusion is supported by the fundamental properties of seismic waves, as S waves cannot propagate through liquids or gases. The presence of S waves suggests that the core does not contain any fluid or gaseous components. Therefore, the core's composition is confirmed to be solid based on the behavior of S waves. Understanding this phenomenon is crucial for insights into planetary geology and core structure.

Please justify your answer with Relevant Equations and show your work. Thank you.
 
S waves can transmit only in solid substance
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
