That's true.
Newton's law of universal gravitation says that the gravitational
force between two objects is

F = G · M₁ · M₂ / D² .

There's no note under the equation that says "only up to
this certain distance, and zero any farther than that".

The equation is true no matter how gigantic the distance
is between the objects.

Answer:

The time is $t = 8.78 \ s$

Explanation:

From the question we are told that

The initial height of the eye is $h _1 = 20 \ cm = 0.2 \ m$

The height of the eye when you jumped up is $h_2 = 150 \ cm = 1.5 \ m$

An illustration of this question is shown on the first uploaded image

Generally the radius of the earth is $R = 6.38*10^{6} \ m$

Now from the diagram first sun means first time you saw the sun and the second sun means second time you saw the sun then

H is the height increase when you quickly stood up which is mathematically evaluated as

$H = h_2 -h_1$

$H = 1.5 - 0.2$

$H = 1.3 \ m$

Also $\theta$ i the angular displacement between the first and second position and from geometry it is also the angle at one of the sides of the right angle triangle
