Yes. It is true that insulation with a high R-value would speed up natural conduction.
Heat transfer is in three modes. Conduction, convection and radiation. In case of conduction, the speed of transfer depends on the conduction property of the material. In case of convection, the speed of transfer depends on the density of the liquid. In case of radiation, the speed of transfer of heat is at the speed of light in air medium and a little bit less in other denser medium.
Conduction is the slower compared to the other two convection and radiation. Radiation is nothing but electromagnetic wave which travels at the speed of light. It is the fastest. Convection is due to free movement of liquid molecules so it is also faster compared to the conduction becuase conduction is passing the disturbed information form one molecule to the other. Here disturbance is in the form of vibration.

inertia
A bow wave is produced when the speed of the source exceeds the natural speed of surface waves in the medium (water). This effect is characterised by the disturbance spreading out in a 'V' formation behind the boat.
Myalin sheath gives insulation to the neurons. They also hasten the nerve conduction by saltatory conduction.
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.

The measurement of the speed of conduction of impulses down a peripheral nerve.
...in a myelinated axon.
Nerve conduction velocity studies (NCV) are used to measure the speed with which an electrical signal is transferred along the nerve.
True
Procedure that measures the speed at which impulses move through the nerves.
By myelin sheath.
First, do you're own anatomy homework in the future. Second, the number of synapses effects the overall time it takes for the signal to go through the reflex arc.
The conduction speed slows when it reaches the bundle of His, and then speeds up as it travels along the Purkinje fibres to the base of the ventricles.
