Question

question 5
if the sun somehow became twice as massive, your weight as normally measured here on earth would
not change.
quadruple.
double.

question 6
when you step on a weighing scale at noon, the earth pulls you down and the overhead sun pulls you upward. the reason the suns pull doesnt decrease your weight at noon is because
the suns pull on you is negligibly small.
of tidal effects in the \solid\ earth.
the weighing scale is calibrated only in earth weight.
the suns pull is cancelled by the gravitation of other celestial bodies.
you, the scale, and the earth are in free fall (in orbit) around the sun.

Explanation:

For Question 5, weight is the force of gravity on an object. The gravitational force between two masses (you and the Earth) is given by $F = G\frac{Mm}{r^{2}}$, where $G$ is the gravitational constant, $M$ is the mass of the Earth, $m$ is your mass, and $r$ is the distance between you and the center of the Earth. If the sun's mass doubles, the gravitational force between the sun and the Earth - and by extension, the overall gravitational - related interactions in the solar - system context change. But your weight on Earth is determined by the Earth's gravitational pull on you. Since the Earth's mass and your mass and the distance between you and the Earth's center remain the same, your weight on Earth would not change.
For Question 6, the sun's gravitational pull on you is much smaller compared to the Earth's gravitational pull on you because the sun is very far away. The weighing scale measures the normal force exerted on you by the Earth's surface, which is equal to your weight on Earth. The sun's pull is negligible in comparison to the Earth's pull for the purpose of weighing on Earth - based scales.

Answer:

Question 5: not change.
Question 6: the sun's pull on you is negligibly small.
