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.
There are three types of rocks:
Igneous form from the cooling and solidification of magma or lava.
Sedimentary form from pieces of other rocks.
Metamorphic form from the warping of other rocks due to heat and pressure.
Hope this helps!!
The answer is C: irrigation
Answer:
They all travel the same speed.
Explanation:
In the vacuum region , all the light or waves , travels at the same speed , i.e. , at 299,792 kilometers per second , due to the free space available without any obstruction or hindrance .
Being it to be X - rays , Visible light , Infrared light , all travel at the same speed ,
Hence , the correct answer to the statement given in question would be , They all travel the same speed .
