Answer:
The radar scanner is an aerial which rotates continuously. The aerial alternatley transmits and receives in quick successio
Explanation:
When Amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.
All of these observations indicated the presence of covalent bonds.
Pol determined that the pH of the sample is 7, which shows the sample is neutral.
Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.
Answer:
Polyethylene glycol.
Explanation:
The abdominal pain might occur in the area of the pelvic regions and the chest area. The lower abdominal pain is common in children that might occur due to the constipation.
The increase or the presence of the polyethylene glycol in the abdomen can cause pain. This affects the bowel movements, bloating, vomiting, diarrhea and in excess condition may also cause the rectal bleeding in the children as well as in adult.
Thus, the answer is polyethylene glycol.
Answer:
The problem needs to be stated at the beginning of the process.
Explanation:
Conclusions are formed at the end.
It is VERY important to form a hypothesis.
And data can be analyzed many many ways.
Answer:
D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Explanation:
Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.
