Answer:
The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).
The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.
Other differences are summarized in a tabular form attached below.
0.12 J/kg . K
Explanation:
Given parameters:
Mass of metal = 20g
Quantity of energy = 30J
Temperature = 12.5K
Unknown:
specific heat = ?
Solution:
The specific heat of a substance is the amount of heat required to raise the temperature of a 1g of the substance by 1K
It is given as:
C = 
input the parameters:
