I was thinking of using related rates as my ia topic but Im not sure how to apply related rates into physics or medicine. Thank you. When a pendulum is displaced sideways from its equilibrium position, there is a restoring force due to gravity that causes it to accelerate back to its equilibrium position. Thus \({dT\over{t}}\) < 0. So, here it goes: All around us, changes happen. Find amount of salt in the tank at any time \(t\).Ans:Here, \({V_0} = 100,\,a = 20,\,b = 0\), and \(e = f = 5\),Now, from equation \(\frac{{dQ}}{{dt}} + f\left( {\frac{Q}{{\left( {{V_0} + et ft} \right)}}} \right) = be\), we get\(\frac{{dQ}}{{dt}} + \left( {\frac{1}{{20}}} \right)Q = 0\)The solution of this linear equation is \(Q = c{e^{\frac{{ t}}{{20}}}}\,(i)\)At \(t = 0\)we are given that \(Q = a = 20\)Substituting these values into \((i)\), we find that \(c = 20\)so that \((i)\)can be rewritten as\(Q = 20{e^{\frac{{ t}}{{20}}}}\)Note that as \(t \to \infty ,\,Q \to 0\)as it should since only freshwater is added.
