AI Thread Summary
To find the density of the stone, first calculate the buoyant force, which is 15 N. This indicates that the volume of the stone is equal to the volume of water displaced. Using the density of water (1000 kg/m³), you can determine the volume of the stone based on the buoyant force. Finally, divide the mass of the stone (calculated from its weight of 50 N) by the volume to find its density. Understanding these steps is crucial for solving similar problems in physics.

Homework Statement



When a 50 N stone is attached to a spring scale and is
submerged in water, the spring scale reads 35 N. What is the density
of the stone?

Homework Equations





The Attempt at a Solution


I found that the buoyant force is 15 N but i don't know what to do after. Can someone please help me step by step. I need to know this for my final tomm and I am stressing out.

i know it becomes 1000(50)/ 15 but i don't know where the 1000 came from. can someone please help?
 


Now you know the buoyant force you also know the volume of the boulder is the same as the volume of displaced water. So you can work out its volume in terms of the density of the water. Next you just divide its mass by the volume to find its density.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
