Yes, conduction through the autonomic efferent chain is generally slower than conduction through the somatic motor system. This is because the autonomic nervous system involves two neurons in the pathway (preganglionic and postganglionic), which introduces a delay in signal transmission compared to the direct pathway in the somatic motor system with only one neuron.
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
The somatic nervous system controls the voluntary movement of skeletal muscles, such as when you move your arm. The autonomic nervous systems controls the involuntary actions of internal organs and glands. The beating of your heart is controlled by this system. The autonomic nervous system is further broken up into two parts: the sympathetic, which controls arousal (think fight-or-flight), and the parasympathetic, which controls calming (think rest and digest).
The autonomic nervous system regulates involuntary functions like heart rate and digestion, while the somatic nervous system controls voluntary movements. The autonomic nervous system has two branches: the sympathetic and parasympathetic nervous systems, which have opposing effects on the body. The somatic nervous system mainly controls skeletal muscle movement through motor neurons.
somatic is voluntary autonomic is involuntary.
An efferent somatic (pudendal nerve) output to the external sphincter which relaxes the external sphincter and causes the urine to flow through the urethra is the effector part of the reflex arc.
The nervous system is comprised of two parts, somatic and autonomic. The somatic nervous system is the control over your skeletal muscles. It is voluntary. The autonomic system works automatically. It has system wide effects known as sympathetic (fight or flight) and parasympathetic (rest and digest).

Yes. You are right. Most probably nausea is mediated through autonomic nervous system.
Conduction is the type of energy transfer that occurs when heat is transferred through matter by molecular activity. In this process, the energy is passed from one molecule to the next through direct contact.
