Answer: So, a line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
Explanation:
Answer:
Hypothesis---experiments----results----conclusion.
Explanation:
First we make a hypothesis means a statement about why the tree looks unhealthy. In this segment of scientific method we have to test the hypothesis through experimentation. After that we have to take the readings of various parts of the tree and analyze the data to find out the problem. In the next step, we have to made the results on the basis of the data that is obtained. In the last we have to write the conclusion of the analysis and see the hypothesis.
Answer:
it depends on density which causes oil to float on water
Explanation:
imagine wearing socks soaked oil and walked in water :0
The calculation of pH is based on the activity (aH) of hydrogen ions (H+) dissolved in solution. Specifically, the pH range of numbers is based on a logarithmic scale:
pH=-log (aH)
Log functions are used to rescale very large numbers (or very small numbers) into values much closer to 1. This is often done to deal with more reasonable
Numbers (for pH, 1 to 14). Mathematically, the negative sign in the formula means that pH must be less than 1.
The lower the number on the pH scale, the greater the concentration of hydrogen ions and the greater the material's acidity. The higher the number assigned on the pH scale, the greater the concentration of hydroxide ions and the more basic, or alkaline, the material.
The answer is 4.
Answer:
the partial of colloidal are smaller and they are not heavy whereas the partial of suspension are larger but they are heavy and less movement thus they settle down due to gravity
