1 answer:
Orlov [11]3 years ago

Answer:

(c.) as the force of Earth's gravity on an object increases, the object's mass increases

Explanation:

Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".

It is mathematically expressed as:

    F = \frac{Gm_{1} m_{2} }{r^{2} }

F is the gravitational force on either particle

m₁ and m₂ are the masses

r is the distance between particles

G is the universal gravitation constant.

From this expression, we see that the force of earth's gravity is directly proportional to mass.

Chemist preformed Reaction of solid magnesium burning and found that the mass of the magnesium oxide what is greater than the ma
tankabanditka [31]

Answer:

The magnesium reacted with the oxygen in the air.

Explanation:

For argument’s sake, let’s say that the mass of magnesium oxide was 3 g and that of the oxide was 5 g.  

The reaction was

            magnesium + oxygen ⟶ magnesium oxide

Mass:           3 g                                          5 g

Mass of oxygen = 5 g – 3 g = 2 g

The 3 g of magnesium must have combined with 2 g of oxygen to form 5 g of magnesium oxide.
