Why is the center of gravity different between regular and irregular shapes?
Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?
Why is it difficult to stand on one foot as compared to one two foot?
Because your body's centre of gravity is disrupted when you stand on one foot. Standing on both feet, your centre of gravity is equidistant from left to right.
How does the bob affects the period of a pendulum?
The period of a pendulum is totally un-affected by the mass of the bob.The time period of pendulum is given by the eqn.T=2*PIE*(l/g)1/2 ;l is the length of pendulum;g is the acceleration due to gravity.'l' is the length from the centre of suspension to the centre of gravity the bob.ie.the length of the pendulum depends on the centre of gravity of the bob,and hence the distribution of mass of the bob.
What is center of gravity of circle of radius r?
It is the centre of the circle. The size of the radius makes no difference.
What is the name of that radius which passes through the center of gravity?
Centre of area of a triangle is the centre point for a circumscribed radius which will pass through all 3 vertices of the triangle.
