Re: 2013 HSC physics marathon
If an object travelled at relavistic speeds it would experience mass dilation and its mass would increase. As a result of its mass increasing, its acceleration would decrease, assuming net force is constant. If this trend continues, the final outcome would be that...
Re: mola heat of combustion
change in H=m*C*change in temp
4.18*200*change in temp=836*change in temp
=0.836*change in temp
moles of fuel=grams of fuel/MM of fuel
moles of fuel=0.6/60.094
=0.001
Molar heat of combustion=2021 kJ/mol
and, we know molar heat of combustion is kJ/(mol of fuel) or...
yeah. the only thing that is 'difficult' in geo applications of differentiation is maxima and minima and btw i have first hand experience cos i have an assessment tomorrow too!
