Answer:

At one time the two continents were one landmass

Explanation:

If scientists find the same types of plant fossils on the eastern coast of South America and the western coast of Africa, this suggests that at one time, the two continents were one landmass. When the continents separated, the communities of plants were split, resulting in identical fossils on each coast millions of years later.

A substance with a density of 2.70 g/mL occupies a volume of 21.3 mL. What is the mass of the sample? Report your answer in unit
katen-ka-za [31]
We know the formula of the density:
ρ =\frac{m}{V} ;
So the mass will be equal to:
m = ρ * V = 2.70  * 21.3 = 57,51 g = 57510 mg of substance.
So the answer is 57510.

Which one of Newton's Laws fits this statement: More mass means more force needed to accelerate?
ivolga24 [154]

Answer:

Newton's Second Law

Explanation:

Newton's second law basically states that the acceleration of a body which is produced by a net force is directly proportional to the magnitude of net force applied in the same direction.

This tells us that

     F   is directly proportional to a

⇒ F= ma

So we can also state from the above equation, that when we have more mass, we need more net force to accelerate it. Here, we are keeping the acceleration constant so we can surely say that force and mass varies directly.

Therefore, we have made good use of Newton's Second Law of motion to arrive at this conclusion.
