Sorry i posted the wrong question? I tried to say why Ampere is the basic/fundamental unit although it is derived from charge/time(columb/sec)

Why ampere is not a S.I unit?

use T=(2*3.14(I/mgr)^(1/2)) r is the distance from center of mass Then inverse T to calculate the value of f.

donot only count the accident done by the human, think how many times human have saved from happening an accident.. it would be better to implicate robot only after inventing artifical intelligence... mathematics and logarithm could not stop sudden accidents...

what about the probable accident ..can robot react on that situations?

what about the black holes? am confused?

this accn.. u solved is for t he pulley not for the block B so use the principle of energy conversion to solve the problem then it will give the acceleration for block B..

i think clouds can also do the same thing but am not sure whether it is a material or not?

1- MA=(effort distance/load distance) just use the formula to claculate here load distance is 11m and MA is 48 so effort distance or length of rope is 48*11

3- u may use simply the Newton'ssecond law..velocity has nothing to do with the force since acceleration is given just divide force by accelaration to get the mass

You use the Stoke law n(viscosity)=[2(density of steel-density of oil)*g*R]/(9v1) v1 is the velocity for steel Again use the same formula for The case of aluminium and divide one equation with other..so that only the unknown will be the density of oil
