Answer:
G
Explanation
The acceleration of gravity is constant, and = 9.8 m/s² , no matter what mass of the object is. Initial speed for both objects = 0 m/s. So, after 2 sec the objects will have the same speed and the same distance.
Answer G: speed=v, distance =d.
A coefficient is a number placed in front of a chemical symbol or formula that shows how many atoms or molecules of the substance are involved in the reaction.
Answer:
The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
Answer:
look for the "W" in the North. Remember that, the "W" may be on its side or inverted to form an "M." If you can recognize the Big Dipper (Ursa Major), the two stars at the edge of the Dipper point toward the North Star (Polaris)
Explanation:
Answer: When the distance between the two object triples then the gravitational force is reduced by one ninth (1/9)th between objects. Gravitational force is inversely proportional to the square of the distance of two object.
Explanation: Therefore, the gravitational force is reduced by the square of the distance between objects.
