The quanaty of charge $Q$ in coulombs (C) that has passed trrough a point in a wice wo to time $t$ (measured in seconds) is given by $Q(t)=t^3?4P^2+6t+t$. (The unk of cuerent is an ampere $1A$ = 1 C/s. (a) Find the current (in A) when $\mathrm{t}?0.6\mathrm{s}$ (b) Find the current $($ in A) when $t=1$ s. At what time (in s) is the cuerent the lowent?
