I think the last option is the correct answer. <span>The powder increased the hydrogen ion concentration of the solution. The said statement is the inference we can make from the situation. pH is the measure of hydrogen ions in a solution. The powder when added in the solution most likely dissociates into ions, especially hydrogen ions, thus decreasing the pH.</span>
Answer:
Explanation:
It may not make any difference. The information missing is the radius of the planet.
However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..
The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase. The question is done by a proportion.
The Solar System model that changed the view of the people about the Earth and the other objects in the sky was proposed by the Polish astronomer Nicolai Copernicus in the 16th century.
Copernicus, by observing the sky and the objects on it, managed to get to a conclusion that drastically differed from the viewpoint that was in place for almost 2,000 years. He proposed that the Earth is actually not the center of the universe, but that that position is held by the Sun, while the Earth and the other planets are spinning around the Sun.
In the Solar System model we can observe the Sun as the largest object, situated in the middle, being static. All the other planets, including the Earth, are spinning around the Sun. The Moon on the other hand is spinning around the Earth, being the only object to do so, but it is also spinning around the Sun as the other objects.
