AI Thread Summary
To find the mass of a mysterious object when only the area is known, the mass per unit area must also be determined. In this case, the average mass per unit area from a previous lab is 0.285824 g/cm². By multiplying this average by the object's area in cm², the total mass can be calculated. This method confirms that knowing both area and mass per unit area is essential for calculating mass. Therefore, the approach of multiplying the average mass per unit area by the area is correct.

Homework Statement


i'm suppose to find the mass of a mysterious object(a tile)i i know the area, which is centimeters squared, and asked to find the mass. would i just multiple g/cm^2 and my area together to get the mass?

Unless you know the mass per unit area you can't get the mass from the area alone.
 
well the average mass per unit area we had from this lab was 0.285824 g/cm^2. so if i multiplied the average x area i would get the mass?

then yes.
 

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...
