The molecule of ozone (O₃) consists of three oxygen atoms bonded together. Therefore, the atomicity of oxygen in ozone is 3, as there are three oxygen atoms in one molecule of ozone.
In the system shown below, $x(t)=\sin(t)u(t)$. In steady-state, the response $y(t)$ will be 
The time constant of the network shown in the figure is 
The parallel RLC circuit shown in the figure is in resonance. In this circuit,
