Answer & Explanation:
Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.
Crest: points A and E
Trough: points C and J
Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.
Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).
I asked that question on my brainly account to answer your question so the people that answerd my question said this is right I HOPE IT IS!!
Answer:
D: Increasing temperature
Explanation:
From collision theory, we know that the more the increase in collisions, the faster the rate of the chemical reaction.
Now, the amount of solid solute in a solvent will change with a corresponding change in temperature. What we mean is that, the higher the temperature increases, the higher the number of collisions between the solvent molecules as well as leading to an increase in the solute particles which will mean an increase in the amount of the solid solute dissolved. The correct answer is option D.
Answer: Each trial was repeated several times during the experiment.
A scientific design refers to a scientific plan or methodology, which needs to be followed to perform a experiment so as to obtain accurate and appropriate result matching with the situation of the hypothesis. Each trial was repeated several times during the experiment best describes an experiment that had a good scientific design because trials in an experiment brings either concordant or consistent results or inconsistent results. The concordant results suggests that the methodology applied is correct, and inconsistent results show that methodology applied is incorrect.
Answer:
The last one, to swim
Explanation:
The function of cilia and flagella move liquid past the surface of the cell. For single cells, such as sperm, this enables them to swim. For cells anchored in a tissue, like the epithelial cells lining our air passages, this moves liquid over the surface of the cell (e.g., driving particle-laden mucus toward the throat).
