centrifugal force is a fictitious force. What is happening is that since the earth itself is not a rigid body it will deform when under motion. Although gravity attempts to make the earth spherical, as it is rotating the earth deforms, in such away that it flattens to become an oblique spheroid. This happens as the material at the equator must have a net resultant centripetal force (not centrifugal) which causes its position of equilibrium from the center of the earth to be further away than at the poles as they do not have this force as they are not rotating around the center of mass.
A dish shaped large muscle which moves up and down when there is contraction and expansion of lungs is the diaphragm which is present between the chest cavity and lower abdominal region. The action of the diaphragm is affected by an inflammation occurring below the muscular disc which will affect the process of breathing. The forceful breathing may result in strain and stress in the back muscles of the human body. This in turn causes pain in the shoulder.
Answer:
d. H + O2 ------ H2O
that's the formation of water
Answer:
361.46 N
Explanation:
= Coefficient of thermal expansion = 
Y = Young's modulus for steel = 
A = Area = 
= Original length = 1.28 km
= Change in temperature = 
Length contraction is given by
Also,
The tension in the wire is 361.46 N
