To determine the length of the second pendulum || second Pendulum || #activity @a2zpractical991

These two This was thin. These four This one So hello guys and welcome to my channel Friends, I and Sashas Ishukla And you are viewing A2J practical So, friends, today's experiment is about Basically, Physics 12th Activity No. 2 I am about to leave. So friends, today we will find out Activity No. 2 And whose name is to determine the length of a seconds pendulum And this is a very active activity. Alright, and for carrying out this activity, you will have four to five March. And fronts, this is one of the easiest experiments in physics. Activity Number 2 So, fronts on this practical channel On this A-to-Jet practical, you will be tested on Physics, Chemistry, and All related videos will be available together I have completed all the practicals from 11th to 12th grade on that subject. Please go and check him out. So if you liked it, please subscribe to this channel Subscribe and support me, and if If you liked this video, definitely share it with your friends Share it, I'll be active on your activity number 2 Your Activity Number 2 Vernier scale on Who was doing zero touch Where were you teaching at 1.9? The number of divisions on the vernier scale How much is 0.01? The vernier scale reading I obtained How many were there? It was a 6, 6 coincidence. You saw it To perform this experiment You'll get a fever, that's right. I am about 100 cm tall. I have taken a 100 cm thread. Because I have to perform the experiment Performing Linth-wise 80, 90, and 100 Friends, I have a bob at my place. Alright We also need to find the radius for Bob. I will tell you how to find the radius of this. And this will surely give you a stand that feels just right. Here is my stand. This is one I have here So this rubber cock here First, you need to take the length. It's a bus scale. So, what should I do with the scale? A 100 cm one I have a 100 cm one The thread is fine, okay We will see your filai 100 cm What is it from here to here? It's exactly 100 cm. What am I supposed to do with this now? I've just found out, it's 100 cm. So I'm here, this thing that's mine So this rubber cock here I'll attach it here. First, I basically need to do it at 80. So I was there in the 80s and 90s And what will I keep doing with all these things? Keeping changing them constantly. You must be seeing this bob below, right? Issa You must be seeing the one below, Issa Bob. I'll zoom in on it. You'll have to take a bob from Bob. And where they are connected, that's where blew the wind You will have to do it yourself. Major will remain. So it should be 80 centimeters Alright My heart is broken. So I'll pull it a bit more, along with the upper part I'll take care of it. It is 80 cm. So, Philal This has become my 80 cm. Right. What will you have to see? that you take it from here Alright And Bob's Who is Bob Half of the distance that it had They should be around that much It should be 80 cm. Now 80 cm What is there to see in you? What do you want to see? 20 oscillations For the sake of the child How long do you think it will take? Alright Writing for 30 seconds Writing for 40 seconds They need to see you. So, how do you want to see 20 oscillations? Look here This is a bob haircut. At rest position Now you have to look here So 20 oscillations Such that for 20 oscillations How long does it take? What would you want even in a stop watch? For you first They won't take it even earlier. First, you must see me That you have to take And Here, what should I do with Alka's this eclipser position? I will display it. So if you don't understand the English, I'll also tell you in Hindi. I mean, this is basically a rest bike. So what am I doing with this terrace? I will eliminate this position. I'm leaving from here. So, when I bring it here and place it down, it will move here and come here, only then will it become one. Then it will come from here to here, and it will be two, okay? So how much time does it take for 20 to happen? I have to note this down for myself, so let's begin. So, look, this is the first one I'm taking here. And put it here I'm letting it go. That's it, your one, two This is three This is four, this is five. This is it. This together with this dough Nine What is this ten? What is this? Bar Ther **** Fifteen thousand Session Eight Usnisi And this is twenty Alright then You are seeing that twenty oscillations have been completed About the timing for this 35 seconds How long does it take? You can see it here, it's about 36 seconds Then this will become yours, T1 So, how to find T2 I'm stopping by the Wapet stop. I'll set it to zero and catch Bob with the whip And from the Vaport position But the pre-embNature of this from the return to the return I will display it and from the switch 20 oscillations, what should I do? Count them? Okay. One Two thin Four, these are theirs And how much has it become? Twenty is fine So, Lagaag 37 has arrived here, here. So what you basically need to do is 80 cm I need to take a leak. The dust from here all the way to Bhopal 80 cm and How much does it oscillate in 20 oscillations? What needs to be done to him? You have to major in it, okay? Whatever timing comes, this one here T1 and T2 will be obtained; you can then calculate its mean. So what should I do? I'll make this Fred a bit shorter and lower. Alright, Fred, how much has it become right now? I'll check myself; is this 90 cm? Okay, so this is exactly It is 90 cm, okay So for 90 cm, which is the length I'm considering I'm calculating how much comes in. So, what will you have to do then? We'll have to catch Bob again from behind. Alright, and what will Bob have to do? It will just slightly come here from the rest position. And just as you will let it go So Bob will go from here and come back here. This will become one of your oscillations. So you'll have to take 20, and what else will you have to do with the stopwatch? I'll start if you start here with the stopwatch This came in one This one 19 And how much has it become? 20 So in France, when I saw it, it was at 40. It runs on this. If you are oscillating So if you increase the length So basically, what happens is That time which is ours That time increases for us When you're looking forerais that within a short minimum time 20 oscillations are being completed Your time oscillation is increasing. 40 seconds remaining When we do for 100 It is completed in 43 seconds. So this is a very easy experiment. What do you need to see? if you increase the length Then your timing will also improve. To complete 20 oscillations I will provide you with calculations and graphical things I have been given three observations. Was done for the 80s I had been given the timing. The previous 36 And for Ti-2 39 But when the length was increased to 90 cm I was given team 40. And for Ti-2 39 Then I increased the length and the increase So I met Tom and Jadu. If you had increased the loan So, timing also increases. So, 20 oscillations in its own way After that, this is the length of the pendulum If you are with me It is big that Your 80 cm But for Pranich 80.98 90 100 100.98 36 36.5 39.5 42.5 t
