yes it is 2*10^-4 m^3/sec

oops the question is how high will the water rise??

Homework Statement A cylindrical bucket, open at the top, is 30.0 cm high and 14.0 cm in diameter. A circular hole with a cross-sectional area 1.72 cm^2 is cut in the center of the bottom of the bucket. Water flows into the bucket from a tube above it at the rate of 2.00×10^−4 m^3/s ...the...

i think it should be from 0 to 1

so its V=2PI* (integral 0 to 2) (x-2)x^0.5 -(x-2)x^4 dx

Volume Of solids question help! Homework Statement i) find the area enclosed by the curves y=x^1/2 and y=x^4 ii)find the volume of the solid when the area in part (i) is rotated about the the line x=2 Homework Equations V=PI*y^2dx The Attempt at a Solution wel the area is simple...

The two events A and B have probabilities 0.2 and 0.4. Also P(A intersect B) = 0.08. (a) Are the two events A and B independent? Explain. well since 0.2*0.4=0.8 they are independent (b) Find the probability that either A or B or both occur. 0.2+0.4+0.08=0.68 (c) Find the probability...

yep sorry it shud be 30-(0.509+0.09(303)) but i get a weird answer

anyone have any idea on residuals well i tried this for the first residual at x=303 and y=30 f(x)=303-(0.509+0.09(30)) =2.2 but R tells me it it 1.67 can u tell me what's wrong with this cheers :)

sorry buddy this is the age we live in get used to it lol

calculating residuals help! Along 14 separate sections of highway measurements of trac volume (x) and rate of accidents (y) were taken. x; 303, 294, 242, 236 ,267, 213, 233, 292 ,287 ,215 ,231 ,195 ,255 ,298 y; 30, 27, 23, 20, 26, 20, 22, 29, 27, 20, 23, 20, 26 ,27 (a)Calculate the...

hmmm its a method of integration to calculate volumes by the shell method

ok z=1/2PI*10*100*10^-9 then

the y values should be from 0 to PI/2 therefore how would i take a slice of the shell, would i just integrate ycosy dy :P

i think i have to calculate the voltage across each component as they are in series but not sure how to use impedance on this question
