It is a to my knowledge, but I will give an update when i find out
The major muscles involved while performing a wall sit or squat are the quadriceps muscles.
Explanation:
Exercises like wall sit or squat are an isometric exercises which works the entire group of lower body muscles.
Isometric exercises are endurance building exercises which improves the muscle endurance by holding it in a position for longer time. These exercises does not involve any big bodily movements but works by tensing the muscles.
Both these exercises primarily involve the front thigh muscles or the quadriceps. Squats and wall sits help to tone and shape the quads and other muscles involved. The angle of the body should be maintained at right angle to reduce the pressure on these muscles.
Other muscles which are involved in these exercises are the hamstrings, core, lower back muscles etc.
Answer:
A detergent molecule consists of a polar ionic head and a non polar hydrocarbon tail. Polarity of a molecule is due to difference in electronegativities of constituting atoms. For example O-H bond is polar because oxygen is very electronegative compared to hydrogen (3.44 vs 2.2) so O acquires a partial negative charge and H acquires a partial positive change making the bond polar.
Detergent tail molecule is non polar because it is made of hydrocarbons i.e. hydrogen and carbon atoms. Carbon atoms are bonded to each other and to hydrogen atoms. Electronegativities of carbon and hydrogen are almost same ( 2.55 and 2.2 respectively ). The difference is not much to induce polarity in C-H bond also hydrocarbon tails have maximum C-C bonds which have no polarity because both the atoms are same.Hence, the tail of detergent molecule is non polar.
