The correct answer is: True
Explanation:
Indeed the chemical elements in the periodic table are arranged in terms of their atomic number. They are usually written at the top of the elements in the boxes of the periodic table. Furthermore, in the periodic table, the rows are called the periods and columns are called the groups.
If the first sentence of the question is true, then both a and c are correct. That's (d).
Note: The mechanical advantage of the rig in the picture is actually only 2, but I guess we can't stop to discuss that right now.
This is difficult to explain, but it's hypotonic. HypERtonic is where there is where the cells shrivel up because there is more solute (salt is an example of a solute) on the outside, so the water rushes outward towards it and shrivels the cell. Plants like lots of water so they like to be hypotonic, and since you're adding pure H2O, there is no solute being added, so the solute is in the cell, causing the water to rush in. Isotonic is equal throughout the solution.
Answer:
Explanation:
Assuming the roof is origin and UP the positive direction
d = ½at²
d = ½(-9.8)2.7²
d = -35.721
d = -36 m
