Three of the fundamental constants of physics are the speed oflight, c= 3.0 x 10^8 m/s, the universal gravitational constant,G=6.7 x 10^-11 m^3*kg^-1*s^-2, and Plancks constant, h=6.6 x 10^-34kg*m^2*s^-1
(a) Find a combination of these three constants that has thedimensions of time. This time is called the Planck time andrepresents the age of the universe before which the laws of physicsas presently understood cannot be applied.
(b) Using the formula for the Planck time derived in part (a), whatis the time in seconds?
