D) strongly acid
<h3>Explanation</h3>
A neutral solution have a pH of 7. All the solutions with a pH less than 7 are acid, and the more they tend to 0, the more they are acid. Viceversa with the solutions with pH greater than 7
Answer:If the object's speed increases.
Explanation:
If the object's speed increases, then its kinetic energy will increase. If the kinetic energy increases, the change in kinetic energy will be positive.
Answer:
D. the masses of the objects and the distance between them
Explanation:
Gravitation is a force, a force doesn't care about the shape or density of objects, only about their masses... and distances.
And you can get it using the following equation:
Where :
G is the universal gravitational constant
: G = 6.6726 x 10-11N-m2/kg2
m represent the mass of each of the two objects
d is the distance between the centers of the objects.
Answer:
Lower than it should be.
Explanation:
Hello.
In this case, since the density is computed by:
And we obtain the volume of the solid by substracting the mass of the water and the solid minus the mass of water:
If some water is splashed out of the cylinder, the volume of water will be lower than originally measured, it means that the volume of the solid will be higher than real. In such a way, since the density is in an inversely proportional relationship with volume, as the volume of the solid is wrongly increased, therefore the density of the solid will be lower than in should be.
Regards.
