A Genius Should Help Me With This Physics Calculation. by oocyte: 10:29am On Oct 18, 2020 |
The resistance Rt of a substance at temperature t°c which is measured by a Mercury thermometer is Rt=Ro/1+∆t^2 where Ro is the resistance of the substance at 0°c and ∆=5.0×10^-5, calculate the resistance of the substance at 100°c and 80°c,if the Resistance of the substance is used as a thermometric property for a resistance thermometer, what will the resistance thermometer read when a Mercury thermometer reads 100°c and 80°c ? comment on your answer. please l really need someone to help me solve the calculation,l have exhausted every knowledge l have and they gave this assignment to my sister studying in polytechnic. 1 Like |

First you are to calculate what Ro is by setting Rt to Zero so as to know the resistance at t = 0 degress celsius that is if it is not a contant for every material. Once you have determined the value of Ro; do your calculation for Rt when t=80 and t = 100. Try it out... If it still proves difficult, let me know |

oocyte:remaining part NOTE s,i unit is ohm and not degre celcius as written in the solution i made a mistake.......for the comment aspect u input those values in the formular provided to get temperature reading said "as resistance increases,temperature............. And as resistance decreases,temperature........." 1 Like

oocyte: As a science student, it's been ages I touched physics or math — I only know how to calculate money now. I'm more into practical now, not theories. Sorry I couldn't help. |

we can't do without Google What we don't understand is that these people are setting past questions for us. Any assignments given to me my junior ones, I don't have any problem if I am with a phone. If I can't find the right answer, I will surely find examples.
