AI Thread Summary
To determine the height of the water column when a mercury column is 32 inches tall, one must consider the density differences between mercury and water. Mercury has a significantly higher density than water, which means that the water column will need to be taller to exert the same pressure. The relationship between height, density, and pressure in barometers is crucial for solving this problem. Understanding the equation that connects these variables will aid in calculating the height of the water column. Ultimately, the water column will be much taller than 32 inches due to its lower density compared to mercury.

Homework Statement



Two barometers are made with water and mercury. If the mercury column is 32 in. tall, how tall is the water column?

Homework Equations



Not sure where to begin with this question. Someone please help!

Well, do mercury and water have the same density? Which column do you expect would be taller?

Ask yourself these questions, it will give you ideas about this question:
What are barometers used for?...what do mercury and water have in different in relevance to this question?
 
Mercury has a higher density so the water column will be higher. This doesn't really help me much though
 
Usually barometers are used to measure the atm. so if you know it,then you can use the equation to calculate the height of water if you know the density of water. Not so difficult. :)

EDIT:Do you know the equation relating height density and all that.If you have studied barometers you should know it.

Are you sure about that? What is the density of mercury relative to the density of water?
If a constant pressure P supports a mercury column 32 in. tall, don't you think that the height of the mercury column is somehow related to how dense mercury is?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
