Deceleration isn't a term in physics; you can have positive acceleration which is speeding up and negative acceleration which is slowing down
Use newton's law F = ma
a = F/m
The options of the given are:
A. A large diameter myelinated fiber
B. A small diameter myelinated fiber
C. A large unmyelinated fiber
D. A small unmyelinated fiber
E. A small fiber with multiple Schwann cells
Answer: Option A, A large diameter myelinated fiber.
Explanation:
The conduction of the nerve impulse would be greatest in the myelinated fiber because the main function of the myelin sheath is to increase the speed of the impulse at which the electrical signals propagate.
In case of the unmyelinated sheath the nerve impulse travels slowly as the conduction waves but in case of the large diameter myelinated sheath the signals travel via saltatory conduction( hop)
In this type of propagation the signals are transferred from the node of Ranvier in one neuron to next node which increases the overall velocity of the action potentials.
C.even though there is almost no material in the interstellar medium, but do transfer energy.
Explanation:
Light waves travels through space even though there is almost no material in the interstellar medium but do transfer energy.
A wave is any disturbance that transmits energy from one place to another.
- Light is a form of wave which belongs to the electromagnetic spectrum.
- They are propagated transverse to their source of energy.
- These electromagnetic waves are special types of waves.
- They are distinct because they do not require a material medium for their propagation unlike other waves.
- In the interstellar medium. a vacuum is in place.
- There are no matter that can be used for propagating waves.
- Light waves still passes through because they do not require any medium to propagate.
