edbor:
ibroh22 long time, i see you guys are digging this practical out..

GL guys,,we dey here o

ibroh22:
can you snap how you set up the question 3

dat will b 2maro

let me make my own contribution..
Q1. SHM BIFILAR SUSPENSION someone did put a video which is correct
Q2. HEAT seems all is good
Q3. Potentiometer .. the readings am seeing eh, even up to 2.9v..doesn't the potentiometer wire have resistance? V=KL where v is voltage k is spring constant L is length of wire..so at 100cm mark you should not have up to 2v self.
i made my connection the bulb brightness increases as current and voltage with increases in length

The bifilar suspension, the graph, cuts across both the negative and positive axes? For length 50 and 40cm, I obtained a negative logarithm, going with the trend, as L decreases, the period also decreases.

the connecting wires, also have resistance.

Brymo:
the connecting wires, also have resistance.

quite negligible, because if you use the wire to measure voltage of 2cells 3.0v you will still get 3.0v, any way when i made my connection at 100cm mark on the potentiometer with the bulb connected i had 1.5v as voltage and 0.4A as current

Let's not forget, 2maro by God's grace, let's upload our results as quick as possible for comparison.

the emf not the voltage.

Brymo:
the emf not the voltage.

if you are told to calculate the emf of a cell, the unit is in what?

of course i'll try hopefully won't be distracted

Thanks so much man!

edbor:

volts

At this point, i will advice anyone who is having problems with the connection of the circuit to simply go for question 1 and 2. Question 2 graph will be the easiest!

I wish everyone who is writing or having students writing the physics success in the name of God..

abi o,,,,have u tried the experiment,,,wat are your values

check this video sir

CondomSir,,have u watched the video?

please am new here also a new teacher in the system we all are aware that tumoro is the physics practical day. in fact today cus is 12am already please I need assistance my skull depends on me please somebody

Q3 reading at my own ends:
V= 1.1, 1.3, 1.5, 1.6, 1.7, 1.8
I = 0.3, 0.4, 0.5, 0.6, 0.7,0.8
Slope = 2.254
Intercept = -0.615

ibroh22:
CondomSir,,have u watched the video?

I think i have watched it days back and it includes the movement required here. Right now, i'm with a small java phone that cannot watch video, otherwise i'd have watched it again to confirm

Just bear it in mind that if the question is exactly the same with the one online, just use one hand to pull one end of the rule towards you and use the other hand to push the other end away from you. Then release the rule

Bro what do you need assistance on? Also, you may want to go through the thread from page 0, it could help

you may call me @09060315008

the e.m.f of a cell is d P.d across its terminals, wen it is not connected to any load

Brymo:

okay chief emf.. but i asked the unit, lets not dwell on this.

God bless you for yha kind gesture toward that fella...Don't copy Natureboy91 dat requested for money to help me wen am a novice then....#GodOfWonders

i got 1.75 as slope can't remember the intercept gave everything to my students. .but I'll be with them early today

Brymo:
Remember 2 follow instructions, yellow paper said bulb(touch light). I connected my circuit d bulb came to life. Nobody is talking about heat, which is d simplest. It's on impurity.

Bro, i already told them.

ibroh22:
Am talking about your own value,,did you get it

Yes, two points are tending to the vertical.

Perfectly correct.

lolz, sure. Let's dwell on d most needful. Don't forget roomies, snapshot ur results as soon as possible for comparison, and state emphatically ur constraints.

Look out u, u misinterpreted me. Ask ibroh22 & others who called me if i requested anything. Yeye guy, no wonder some guys are backward, always thinking the opposite. So, all i listed here, i asked of anything, right? Ingrate!
