Homework Statement 1) What is the mass of 100% Ethanol? 2) How much ethanol would be expected from 18% glucose solution? 3) What else will be generated? How can we calculate this amount? Given: Fermentation Equation: C6H12O6(aq) + 2C2H5OH(aq) + 2CO2(g) + Heat...

for the apparent weight i used the formula wapp = mg(1+ay/g) g would be 0.223 but what would ay be?

really? i didn't think a name like that would be pretty serious around here. Sorry, if i offended you.

i got 4.3586 as my acceleration..

k but like what do you mean substitute?

um it doesn't orbit earth.. whoops i mean 1. k but what about finding g?

Homework Statement Communications satellites are placed in a circular orbit where they stay directly over a fixed point on the equator as the Earth rotates. These are called geosynchronous orbits. The altitude of a geosynchronous orbit is 3.58 x10^7 m a)What is the period of a satellite in...

so i should work with diagram b right? to find the acceleration of block a.

oh crud i forgot, it should be Fgx in both questions.

k well for box A i got Fnet = F B on A - Ff and for Box B i got F net = -F a on B - Ff but what would F b on a be equal to if i broke it down into f=ma format? Would it be f= mass of b times the acceleration of b?

Homework Statement Two packages at UPS start sliding down the 20 degree ramp shown in the figure. Package A has a mass of 7.00 kg and a coefficient of kinetic friction of 0.180. Package B has a mass of 12.0 kg and a coefficient of kinetic friction of 0.150. How long does it take package A...

oh cool it was right. Thanks Astronuc.

then for t = 2 to t = 10 Constant Velocity so a = 0 x = 3.924 (8) + 1/2 (0)(8)^2 Took t=8 since 10-2 = 8 x = 31.392m then for t=10 to t=12 x = (3.924)(2) + 1/2 (-1.962)(2)^2 x = 3.924m and the total i got was 39.24 m ( Realized i had an error in there so i changed it)

k well i did for t=0 to t=2 x = (0)(2) +1/2 (1.962)(2)^2 x = 3.924m Vf^2 = (0)^2 +2(1.962)(3.924) Vf = 3.924 is that correct so far?

Basically for t=0 to t=2 i got 3.924 m t=2 to t=10 i got 31.392m t=10 to t=12 i got 27.468m and i got the total to be 62.784m whoops i should start editing my posts instead of continuously posting. Sorry.
