Calculating Specific Gravity and Density of a Body

AI Thread Summary
To find the density of a body weighing 100 N in oil with a density of 0.8 g/cm³ and 60 N in water, the apparent weight formula is applied. The buoyant force must be calculated based on the difference in weights when immersed in both fluids. The solution provided is 1.3 g/cm³, indicating the body's density. However, there is confusion about the application of the buoyant force formula, as the initial attempts did not yield the correct results. Detailed calculations and explanations are needed to clarify the misunderstanding.

Homework Statement



If you have a body that weighs 100 N dipped in oil that has density equal to 0.8 g / cm³. This same body when immersed in water begins to weigh 60 N. How do I find the density / specific body mass?

Homework Equations


Solution= 1,3 g/cm³

The Attempt at a Solution


Already tried using the formula of the apparent weight = actual weight - buoyant and not worked.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
