AI Thread Summary
To calculate the mass of glycerin based on the given energy and temperature change, the equation Q = C*M*(T2-T1) is used. The specific heat capacity (C) of glycerin is approximately 2400 J/kg·K. When using C as 2.4, the calculated mass is 545.63 g, while using the correct value of 2400 results in a mass of 0.55 g. The discussion highlights the importance of using the correct specific heat value for accurate calculations. Accurate calculations are crucial for applications involving glycerin in soap production.

Homework Statement



Glycerin, a major component of soap, is heated before being poured into moulds. Calculate the mass of glycerin if 5.50 x 10^3 J of energy causes a 4.20°C temperature rise.


Homework Equations


Q = C*M*(T2-T1)

I need to look up C which is specific heat for glycerin. I think its 2400 Jkg-1K-1. Or 2.4. I'm not sure

Q = 5.5x10^3 J
T2-T1 = 4.2
C=?



The Attempt at a Solution



I got m= 545.634921 g when I plugged in 2.4 as c.
and m= 0.545634921 g when I plugged in 2400 as c.

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...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
