Come Again? =S Can You Write the way to the answer please :) THANK YOUUU <3

I Asked My Friend, But Thanks Anyways !!! =)

thank you =)

fg +fps = ma where fg is the force due to gravity fps is the force due to the person on the scale ma is the submission of the forces of Fy re-arrange the formula to find Fps.

you mean y=2x for the first line...because I did something similar however I took the limit, since cos x can not have y values larger than 1 or -1, i took 2cosx=1 i get zero and using both methods:Y-Y1=m(X-X1) and y=mx+b i get y=2x. i checked it using a graphical calculator the same answer, y=2x

correct answer! dy/dx = cosx-xsinx.

is 153m the correct answer?

I realized my mistake, i was only finding the resultant for the velocity, not the momentum together, if i do not convert km/h into m/s i get the momentum as 1.24*10^5 is that correct?

I tried solving this by separating the components into the vertical and horizontal, before and after collision. but i only obtain velocity and the deg, however the questions asks for the distance...

Thank you, helped, the equations do balance out, and there are more than one ways to solve this either by multiplying the first equation by 2 and then manipulating further as well as just canceling out and adding all by hess's law.

i tried using it for CH4, below is my working am i correct? cause i researched a website(cannot post link) and it uses enthalpy of formation!!! i am using the molar enthalpy of formation equation: (ndeltaHf products) - (ndeltaHf reactants) CH4 + 2O2 ↔ 2H2O + CO2 deltaCOMB = [(2*-241.8)+(-393.5)]-[-74.6] =-502.5kJ

missing information, * length AB = 0.8m

x-96=29

1.35

Differentiate between the term in the following pairs

co-dominance

I would like to see the work please
