i said the same but others said special relativity doesn't apply when gravity is involved i think?

Couple Multis, same Couple silly mistakes later

Did mass increase or decrease lol If it decreased then release of energu

No way this was easier than last year wth this was def harder

Yea

Apparently state rank cutoff was 93 last year bc of harsh marking

What was the exact question and diagram again for hertzsprung

Jupiter’s moon

For q18 it’s the point where Earth is moving down (point on the left) not sure what letter tho

Confirmed? Is this q18?

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

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

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

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

Nah consensus seems to be a Weight is constant

And for q20 pretty sure it’s a right?

Whatever the left thingo was for q18

yes please !!

parabolically up? Also why mass?
