Thanks to Newton, we now know that the time $$t$$ (expressed in seconds) that an object needs to fall to the ground from a height $$h$$ (expressed in meters) is given by the formula \[ \sqrt{\frac{2h}{g}}\,, \] where $$g$$ is the gravitational constant given by $$g$$ = 9.81 m/s².

On two separate lines:
The time (in seconds, decimal) that it takes for an apple to fall on Newton's head from a height of 6.7 meters. Please pay attention to the fact that Isaac Newton is sitting under the tree with his head 1.37 m above the ground.
The number of tasks (integer) that
Newton's laptop can perform while the apple is falling from the tree, if
you know that Newton's laptop can perform exactly one task in one
microsecond (1µs = $$10^{-6}$$ s).
