State why there is a brief delay in the transmission of an impulse across the synapse?

The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.

How is a stimulus transmitted across a synapse?
Neurons are responsible for transmitting a stimulus across a synapse. The electric potential of the neuron is sensitive to changes in the resting state and sets off electric transmissions.

What does the impulse-momentum theorem state?
Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).
