Re: Any Physics Students On Here? Please Help Me ASAP With These Assignments by Nobody: 5:11pm On Apr 03, 2018 |
We were asked to calculate the difference in length at T2 temperature. We were given L1 for both rods but not L2. L1= 5m Also, we were given the linear expansivity for the both rods. Linear expansivity for Aluminium rod is given as 23*10^-6 Linear expansivity for Nickel rod was given as 13*10^-6 Now when dealing with length, we talk about linearity not the area. The area expansivity (B-Beta) given was just to confuse you. The formula for linear expansivity (alpha) is; Linear expansivity = Change in length (L2-L1)/L1(T2-T1) I.e L.E = (L2-L1)/L1(T2-T1) We have all parameters for all except L2, so we calculate L2 For Aluminum rod. 23*10^-6=(L2-5)/5(70-20) 23*10^-6=(L2-5)/250 23*10^-6 * 250 = L2-5 5.75*10^-3 = L2 - 5 5+5.75*10^-3=L2 L2=5.00575m (For Aluminium Rod) For Nickel Rod 13*10^-6=(L2-5)/5(70-20) 13*10^-6=(L2-5)/250 13*10^-6 * 250 = L2-5 3.25*10^-3= L2 - 5 5+3.25*10^-3=L2 L2= 5.00325m (For nickel rod) Now the question says the difference in length of both rods when the temp is at 70 L2 of Aluminium - L2 of Nickel = 5.00575m - 5.00325m 2.5*10^-3 or 0.0025m (Your answer) PS: (The initial length of both rod was 5m before the temperature increased from 20 to 70, therefore you gotta find the new length first and subtract. Always understand a question first before you solve) (I'll keep modifying until I'm done writing) CC: Preciousgirl 2 Likes |

Re: Any Physics Students On Here? Please Help Me ASAP With These Assignments by Nobody: 5:18pm On Apr 03, 2018 |
chicoMX: This is so wrong. The difference in length of the both rods not the difference in length of individual rods. Not dL of Nickel and dL of Aluminium |

iamsirmichael1:Worked it on black andwhite too but servers shit as usual. Your answer would have been right if your standard form had been right , the linear expansivity values were raised to the powers of negative 6 and the answer concomitantly should be .002575m which approximately equals .0026m 1 Like |

Opentokwowledge: University of Life?? You don't say. Anyways, I'm still a student at a university in Nigeria studying engineering. That's about as much I can say about myself. I presume I'm conversing with my uncle's mate. I liked how you circumvent my question and gave your own answer to your own question. Hehehehe So please Sir, answer 'my' question. We're all in the university of life |
