A copper bar is $80 \mathrm{~cm}$ long at $15^{\circ} \mathrm{C}$. What is the increase in length when it is heated to $35^{\circ} \mathrm{C}$ ? The linear expansion coefficient for copper is $1.7 \times 10^{-5}{ }^{\circ} \mathrm{C}^{-1}$

Yeah. For this problem on the topic of sound waves, we are told that a copper bar is given a blow at one end. The sound of the blow that is traveling through air at zero degrees, reaches the opposite end of the bar 6.4 milliseconds later than the sound transmitted through the metal bar. You want to know the length of the Spar. Now the difference in time of the two sound waves, delta T. Is equal to the length of the bar. El into one over The speed of sound in air at 0°C minus the speed of sound. In copper we see you. So this is equal to the length of the bar. Our times the speed of sound and copper. VCU. My honesty speed of sound in the air divided by the speed of sound and air. Times the speed of sound in copper. And so if we rearrange this equation, we find that L. Is equal to the the A. Times we see you divided by the C. U. Minus V. A. Times the time delayed out of tea. All of these values are known The speed of sound and a. 0°C is 331 m/s And through copper is three 56 Times 10 to the power three meters per second. This is divided by 3560 -331 meters per second times the time delay, which is 6.4 milliseconds or 6.4 Times 10 to the -3 seconds. So this gives us the length of the Bar L. to be two .34 m.

Hello and welcome to this video solution of numerous here you have to tell why the melting point of copper is higher than that observed. So for copper we have the electronic configuration as Oregon three D 10 And Forest one and that for that of zinc it is almost same that is Oregon three D 10. And for us to and we have to remember that during meddling bond formation that the electrons of copper are involved. Right? So metallic the electrons are involved. Okay, and as a result a large amount of free electrons are present. Editors now deal with the business of free electrons, melting point raises okay melting point races. So this is one case and there is also a second case we can consider. So what about the structural, okay structural in case of the eye, corporal crystals and zinc crystals. So corporate has got ccP puppet packing that is cubic close packing structure while that of zinc has http. And due to this, the density of corporate is much more, okay, intensity is much more in case of copper. Now do do do this difference in density? The melting point of corporate is also greater than C. So here we can select option uh option A. That is the dialect concert corporate involved in mentally funding. Right? I hope this is clear to you and have a very good rest of the day. Thank you.

As we all know that the velocity of the sound in solid is given by B. Is equal to under hood. Why buy a roll? Why is the young models of the solid and row? Is the density of the given solid? From the ever data I can write beach proportional to under route. Why? So in this problem we already know that the youngs modelers for copper let it be Y. C. Is equal to 8.9 multiplication tend to the about three P. A. And young modelers object. Why Jack is equal to 8.5 multiplication. 10 to the power three P. A. So the young models of jink YJ at age less than young. Smart lots of copper. So adding jing to copper, so adding drink to cooper, so adding zinc to copper houses did decrease cows. Is the decrease in speed causes the decrease in speed of sound, The speed of sound. So this is our answer.

As we know that Ziada, no, it colorless at to room temperature at room temporary here also see you two CL two. Each can inlays due to the absence of due to the absence of a UNP aired electron. Therefore, here in this problem only option age correct? While the other options are incorrect. So, so here in this problem, Option B, option C, option B are the answers.
