And for q20 pretty sure it’s a right?
Danggggg I guessed the one on the rightWhatever the left thingo was for q18
YeupAnd for q20 pretty sure it’s a right?
yeah but because it wasn’t a horizontal plane mg affected it more and different spots - my teacher thinks it’s d as wellWym it was circular motion for q20. Constant magitude with the axis slightly skewed downwards. Since r was constant
I was meant say products wieghed more then reactants. I swear it said thatmg varied tho ths
it was release of energy - if reactants weigh more than mass has been lost in the form of energy
did the emf graph start at maximum or 0?Yeup
I can’t really remember the question. Guess I’ll cop that one though ggyeah but because it wasn’t a horizontal plane mg affected it more and different spots - my teacher thinks it’s d as well
I got reactants more than products - but if it is products more than you are rightI was meant say products wieghed more then reactants. I swear it said that
Nah consensus seems to be aI can’t really remember the question. Guess I’ll cop that one though gg
Like 37ms at 54 degrees to the horizontalSo what was the answer for the projectile motion question? It was asking for the initial velocity
Oh crapLike 37ms at 54 degrees to the horizontal
SameLike 37ms at 54 degrees to the horizontal
Idk for the 7 marker I just said back emf as one factor and friction separately as another factorWhat did you guys get for the horizontal distance and also for the motor/pully one did you relate the force of friction and force created by the torque of the motor to get the mathematical model
how did you derive the velocity of star B?Like 37ms at 54 degrees to the horizontal
me too - and I used T=niAB as a model and because it said model(s) I used the emf formula as another oneIdk for the 7 marker I just said back emf as one factor and friction separately as another factor
Equate centripetal with grav as both stars on the same circlehow did you derive the velocity of star B?
