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.

Explanation: I'm going to do some more research lol
Answer:
Country which shares a border with the northernmost part of China : RUSSIA
Looking at the map I attached, you will notice that the northernmost part of China is to the North East between 120° E and 135° E. The country that borders this area is Russia.
Countries located between 105° E and 135° E lines of longitude:
Looking at the map and the lines of longitude circled, countries between these two lines of longitude are:
- North Korea
- South Korea
- Philippians
