AI Thread Summary
To calculate the time it takes for light to travel 54 cm through glycerine, the speed of light in glycerine must be determined, which is approximately 2.1 x 10^8 meters per second. The time can be calculated using the formula time = distance/speed. The discussion emphasizes that the aquarium's environment, including air and glass, does not significantly impact the calculation for light traveling solely through glycerine. Therefore, the focus remains on the properties of glycerine for this specific calculation. Understanding these factors is crucial for accurate results.

Determine the time it takes for light to travel 54 cm through glycerine in an aquarium.

Do I account for air, glycerine and glass?

I would answer the precise question given. What's the speed of light in glycerine? How far does it travel through the glycerine? (Given no additional context, the fact that it's in an aquarium seems irrelevant.)
 

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 '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 hanging mass'

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...
