difference between positive acceleration and negative acceleration? difference between hemogenous and heterogeneous? difference between element and compound? difference between true solution and collidal solution?
Answers
Answer:
homogeneous mixture
Explanation:
the particles of homogeneous mixture are very small in size.
the particles cannot be seen with naked eye.
example- salt solution, sugar solution.
heterogeneous mixture
the particles of heterogeneous mixture are very big.
the particles is visible with naked eye.
example- chalk Powder,sand solution..

Answer:
Explanation:
1) That means that the direction of the acceleration determines whether you will be adding to or subtracting from the velocity. Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity.
Positive acceleration means that there is an increase in speed and negative acceleration means that there is a decrease in speed.
2)A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.
