Explanation:
Let acceleration due to Gravity for a planet is given by:

Here,
Escape velocity is given by:

Here,
and g_X = 2g
Therefore,
Answer:
A new substance was formed
Explanation:
According to this question, a shiny and flexible metal called Magnesium (Mg) is burnt in air to produce a white powder that has no shiny or flexible properties, however, has more weight than the magnesium metal itself.
This is possible because a CHEMICAL CHANGE has occured, hence, a new substance has been formed. The formation of a new substance during the burning process (chemical reaction), induced the increase in mass.
It’s hard to perfectly measure the distance something travels, as well as the exact time it takes, making the results have some variation.
Answer:
natural motion and violent motion
