To solve the problem, we need to calculate the induced electromotive force (e.m.f.) in the coil at \( t = 5 \) seconds, given the magnetic flux through the coil as a function of time. The magnetic flux is given by the equation: \[ \phi(t) = 5t^2 + 10t + 5 \, \text{milliweber} \] ### Step-by-Step Solution: ...
