Idk for the 7 marker I just said back emf as one factor and friction separately as another factor

Yeah but it said make a mathematical model

 

[vernburn]

Its age, since mass (absolute magnitude) is an axis on the graph

Absolute magnitude is size not mass.

 

[Time&moretime]

me too - and I used T=niAB as a model and because it said model(s) I used the emf formula as another one

Yeah, I put as friction increased with velocity (dynamic), the load torque on the motor will increase thus the rotor speed will reduce....... due to decrease back emf...... to increase the current and torque.

No I think it’s luminosity

Equate centripetal with grav as both stars on the same circle
Gotta remember r in centripetal is x/2 and r in grav is x, I forgot this so rip

Not sure about that. Because X is distance between the stars. Doesnt say that its the distance between the center of each star. So i used the radius as well

 

[tokyocalling]

Probably around 84 or something

lmao it is not gonna be that high possibly like 78 ish

 

[black.mamba]

Not sure about that. Because X is distance between the stars. Doesnt say that its the distance between the center of each star. So i used the radius as well

No, distance between is x and the stars must be on the same circle (and are a diameter across, on opposite sides of the circle) for gravity to pull each star to the middle of the circle and act centripetally

No I think it’s luminosity

Yeah you’re right

 

[black.mamba]

Yeah you’re right

And we still don’t know if the answer is mass or age lol

 

[Fabrizio]

And we still don’t know if the answer is mass or age lol

Its age

 

[S12345B]

I got tp

can any1 confirm this? i guessed tp

 

[Fabrizio]

Anyone know how quickly physics answers get posted. Like about the same as maths or longer?

 

[Xanthi]

Predictions:

Band 6 - 68
State Rank - 92

 

[black.mamba]

Its age

Confirmed?

can any1 confirm this? i guessed tp

Is this q18?

 

[Fabrizio]

can any1 confirm this? i guessed tp

What question

 

[S12345B]

What question

jupiters moon

 

[Fabrizio]

Confirmed?



Is this q18?

My teacher said. He said its one of the ones where the others wernt possible so by deduction it has to be age

 

[Fabrizio]

jupiters moon

Was that the one where is asked what point the period of orbit of jupitor would be longest

Predictions:

Band 6 - 68
State Rank - 92

Noooooooo sorry ahah not gonna happen

That’s how I got mass lol
