I do not know exactly that if I am actually left-handed or right-handed?
I use my left hand for writing, other than that activities like playing the piano, I need not have to look focus on the right hand, the left hand would need more attention.

Playing of pool and badminton is use of right hand too, only that when my right hand is tired or change of angle, I used my left hand.

I can't shut my right eye long enough, which brain is more in control?

Help - someone gave this puzzle to my 9 year old for a bit of fun to see if he can work it out - I've tried several times but don't seem to get anywhere................

A bath takes 5 minutes to fill with the plug in. It takes 8 minutes to empty when you take the plug out. How long does it take for the bath to fill with the plug out ?

Cheers
Andrew

assuming that angular velocity is constant & axis of rotation is thro' the center of the disc,how does the circular disc distribute the tangential velocity linearly (i.e. ang vel * radius) along the radius.
alternately what does one mean by velocity increasing radially and how is this achieved by the material of the disc?

then consider sulphur is yellow.It mean sulphurs atoms are yellow.It also mean that electrons protons neutrons and other subatomic particles are yellow which make its atom yellow which in turn make sulphur yellow.is it true?
if true then in case of a blue element all its sub atomic particles are blue.
how is this colour distribution applied on subatomic particles of other substances

Very small crystals composed of 1000 to 100,000 atoms, called quantum dots, are being investigated for use in electronic devices.

(a) Calculate the mass in grams of a quantum dot consisting of 1.200 104 atoms of silicon.

(b) Assuming that the silicon in the dot has a density of 2.3 g/cm3, calculate its volume.

(c) Assuming that the dot has the shape of a cube, calculate the length of each edge of the cube.
