Assertion (A): The function ke^st with both σ and ω positive and s > 0 depicts a sinusoid whose amplitude increases with time.

Reason (R): If σ = 0, ke^st becomes a sinusoid.

1. On executing the return statement, it immediately transfers the control back to the calling program.
2. There is no restriction on the number of 'return' statements present in a function.
3. The 'return' statement must be present at the end of called function.

Assertion (A): Capacitance effect can be used to measure thickness of sheets, displacement and pressure.

Reason (R): Capacitance between two plates depends on the area of plates, distance between plates and permittivity of medium.

Assertion (A): Feedback control systems offer more accurate control than open loop systems.

Reason (R): The feedback path establishes a link for comparison of input and output and subsequent error correction.
