chemistry-igcse1.weebly.comSo if you record the temperature change during heating a solid, the temperature will first rise, then it will remain constant for a while (this is the melting point) and then it will rise again. The following figure is a heating curve of a solid. At point ‘A’ the state is …

The Tg was evaluated according to DIN EN ISO 11357-2 on the basis of the curve, the slope of which is stepped in the transition range. The torsion modulus and the damping curves shown in figs. 8 to 13 enable Tg’s to be defined on the basis of the damping maximum. Since this is a

Exploring Parabolas: The shape of a satellite dish
spacemath.gsfc.nasa.govon the curve of the parabola, that means that we can solve for a for this particular dish. We get a (5.0) 2 =1.0 so a = 1/25. Then the focus will be at f = 1/(4/25) so f = 25/4 = 6 ¼ meters above the bottom of the dish. Let’s design a few parabolic reflectors that we can use to reflect and concentrate sound waves, or sunlight! Problem 1
