It is a physical change. One is physically change the wheat from one form to the other.
D=-5m
a(gravity)=-9.8m/s^2
vi= 0m/s
t=?
use equation d=vi*t+0.5a*t^2
because vi=0, you can cross out vi*t because anything multiplied by 0= 0
rearrange the equation to say t^2=d/0.5a
t^2= -5/-4.9
t^2=1.02
find the square root...
final answer: t=1s
The radiation detector that uses detection of flashes of light is a <u>scintillation counter.</u>
<h3>What is a scintillation counter?</h3>
A scintillation counter detects and measures ionizing radiation by using the excitation action of incoming radiation on a scintillating substance and detecting the light pulses that arise.
One of the most critical considerations for anyone who operate with or near radiation is being aware of the amounts of radiation present.
This is generally performed through the use of several types of radiation detectors.
The radiation detector that uses detection of flashes of light is a scintillation counter.
Hence,scintillation counter is the correct answer.
