Question

What is plank time?????????​

Answer 1

In a right-angled triangle, the sine of an angle (θ) is the ratio of its opposite side to the hypotenuse. i.e., sin θ = (opposite side) / (hypotenuse). Then by the definition of inverse sine, θ = sin-1[ (opposite side) / (hypotenuse) ] .

Answer 2

Answer:

The Planck time is the time it takes for a photon to travel a distance equal to the Planck length: = 1.62 × 10-35 m. and is the shortest possible time interval that can be measured. With its associated Planck length, the Planck time defines the scale at which current physical theories fail.
