Immediately following the arrival of the stimulus at a skeletal muscle cell, there is a short period called the latent period during which the events of excitation-contraction coupling occur.
This process is a connection between transduction in the sarcolemma and the initiation of muscle contraction. Sarcolemma is nothing but the cell membrane of skeletal muscle.
A single muscle twitch has a latent period, a contraction phase when tension increases and a relaxation phase when tension decreases.
The period of incubation, the interval preceding exposure to a pathogen toxin or radiation, and when effects occur. Muscle contracting, the time between a nerve stimulus and muscle contraction.

Answer:
Measurement is called the process of finding exact quantity of a substances.
B) The amount of work done
Answer:
yᵢ = h
vᵢᵧ = 0
Explanation:
Let initial velocity = u
final velocity = v
height = h
acceleration due to gravity = g
Therefore fro equation of motion,
Here initial velocity is zero.
Hence, 
but since it points downward and you positive is taken in the up direction
