Damon is Stating that- F=1/T T=2*pi/w so T= 2pi/sqrt(k/m) using our values T=2pi/sqrt(682/13.50)=.884004 Therefore F=1/.884004 -->=1.13121 For the second part acceleration=Aw^2 which must equal the acc. of gravity(g) g=Aw^2 w=sqrt(k/m) so w=7.107638 plugging into our ...

So I have that 1.51 V - 1.065 V = .445 V = E and that ΔG = - 10 mol * 96485 J / mol*V * .445 V ΔG = -429358 J so then plugging in: K = e^(-(-429358)/(8.314 J/mol*K * 298 K)) K = 1.82 * 10^75 The 'correct' answer appears to be 1.5 * 10^75 , but that's not...

Very close. Remember to change mm to meters. Greatly effects answer. Va/Vb = sqrt[(Tension1/Tension2)*(Diameter2^2/Diameter1^2)] Va/Vb = sqrt[(420/840)*((5.9E-4)^2/(1.3E-3)^2)]

Try to use P2-P1 = ρ/2(v1^2-v2^2) Derived from P1 + 1/2ρv1^2 = P2 + 1/2ρv2^2 Then A1V1 = A2V2 is from continuity and can be expressed V1 = A2V2/A1 You get the equation P2 - P1 = ρ/2((A2V2/A1)^2 - V2^2) via substitution And then simplify to 2(P2-P1)/ρ...
