Specific heat capacity and magnification

AI Thread Summary
The discussion revolves around deriving the formulas for specific heat capacity and magnification power of a lens. Specific heat capacity for an ideal gas at constant pressure is expressed as Q/(n*dT), where Q is the heat added, n is the number of moles, and dT is the temperature change. The ideal gas law, pV=nRT, can be utilized to find temperature at various stages. The original poster seeks assistance with these derivations, indicating a need for clarity on the concepts. The conversation emphasizes the importance of understanding these fundamental physics principles.

Hello, Faizan Here
Can anyone show ne how to derive the formula of specific heat capacity pls.? Also i need the derivation of the formula of magnification power of a lens? Thanks in advance to anyone who helps me.

Don't you have a textbook?
 
to obtain specific heat capacity of an ideal gas at constant pressure =
Q/(n*dT) where Q is amount of heat , n is numba of moles of gas and dT is change in temp. You can use pV=nRT to find the temp at different stages where R =8.314;
hope that helps
peace
 
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 .
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...
