or do you not have any.
bc i picked Humans sometimes modify their environment to allow travel and the movement of goods.
Answer:
Tides
Explanation:
The moon affects the tides. The moons gravity is connected to Earth, and since the oceans cover most of Earth, the moon's gravity creates low and high tides.
By using ordinary language to describe the events surrounding the nose's disappearance arrived at this answer after reading a portion o f the story involving the disappearance of the nose. "But, to his unbounded astonishment, there was only a flat patch on his face where the nose should have been! Greatly alarmed, he got some water, washed, and rubbed his eyes hard with the towel. Yes, the nose indeed was gone! He prodded the spot with a hand—pinched himself to make sure that he was not still asleep. But no; he was not still sleeping. Then he leapt from the bed, and shook himself. No nose! Finally, he got his clothes on, and hurried to the office of the Police Commissioner. "In the above quote, ordinary language was used. It would seem as though losing a nose is no big deal for the character. Instead, he is more concerned of going to the office. His reaction is quite unbelievable.
Answer:
B and C
Explanation:
B. In a given rock sample, the amount of Silicon-32 isotopes gets divided in half about every 170yrs.
This is the concept of half-life. Half life is the time take for half of a radioactive isotope to disintegrate. The shorter the half life the faster the isotope disintegrates.
From the question, we were told that it would take 170yrs for half of the isotope of Silicon to disintegrate to Phosphorus. This is the half life.
C. The half life can be used to determine the amount of Si-32 that has decayed from the time closure temperature was reached.
The closure temperature is very important in radioactivity. It is the temperature at which a system has cooled and there is no resulting disintegration of parent and daughter isotopes.
From first order kinetics, we know that the rate at which radioactive elements decay at any time is directly proportional to the number of radioactive atoms present. A knowledge of the half life helps to figure out the number of atoms that has decayed in time.
