How do we calculate and compare K values proportionality? Detauled method please? That 10% one?

 

[Binod Shakya]

it is kind of tricky one
First of all after u got two different value of constant"K".
Pick the small value of 'k'. Then
Find the value of"k+percentage uncertainty of k". U have calculated percentage uncertainty from previous stuffs. So no need to worry.
Then if calculated value exceeds the greatest value of 'k'. i,e another value of 'k'.
Then it supports ur idea, otherwise it wouldnt
Hope u will get through this.
U can also pick greatest value of 'k' calculated.

hey fellas, when drawing a graph, can u plot points on the axis? and can u draw the graph in landscape?

Bro I didnt get your explanation. Tell me how to calculate the %uncertainty of k?

 

[meobunny]

Thank you so muh fellow and he means that you found the k value uncertainity in a previous part, (they will ask th3mselves) so you add it with smallestt K values calculates and see if it exceeds greatest k value then its proptional right? But question is will they always aak us to calculate uncertainity? What if they dont? and what is that method whereyou compare uaing percentages?

Bro I didnt get your explanation. Tell me how to calculate the %uncertainty of k?

percentage uncertainty of 'k' is what u have calculated in previous no.
And get it clear. Look out some paper and u will get through it

previous no?

 

[Binod Shakya]

previous no?

Which session are u trying to solve? Can u plz tell me

 

[Xeshan16]

34

I mean year, session and question no.

 

[Xeshan16]

I

I mean year, session and question no.

I am asking a general question not specific to any paper. BTW it is there in many papers. It is a frequent one

So note down there is percentage uncertainty to be calculated of anything. Read question from the top and mark on the percentage uncertainty to calculate. Dont look for constant only.
Dont get puzzled dude.

I
I think there are even more apparatus

Why and how do you know?

 

[meobunny]

You're welcome ....!!

What was ur gradient and did your valuems support relation? And ur intercept must be negative right? And what was ur diameter? Mine was 0.5 :/

 

[Binod Shakya]

What was ur gradient and did your valuems support relation? And ur intercept must be negative right? And what was ur diameter? Mine was 0.5 :/

Gradient comes around 3 and intercept -4. My result doesnt support the idea

 

[meobunny]

Woah :O it didnt? Ya Allah save me and what was ur diameter?

 

[Binod Shakya]

Woah :O it didnt? Ya Allah save me and what was ur diameter?

Diameter was around 0.3 or 4
Did ur result supported the idea?

 

[Ikram Khaliq]

Gradient= 3.something
Y-intercept= -4.something
Diameter= 0.375 cm
Suggested relationship not supported (percentage uncertainty in the values of k= 24%, criterion= 15%)

 

[Ikram Khaliq]

percentage uncertainty in the value of diameter= 1.33%?

 

[Ikram Khaliq]

were the velocities increasing or decreasing?
