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.

When the mass of the cart changes, the time to travel at 4.6 m/s is 28.11 s.
<h3>
Acceleration of the mule</h3>
The acceleration of mule is calculated as follows;
a = v/t
a = 5/10
a = 0.5 m/s²
<h3>For constant applied force</h3>
F1 = F2
m₁v₁/t₁ = m₂v₂/t₂
(180 x 5) / 10 = (550 x 4.6)/t
90 = 2530/t
t = 2530/90
t = 28.11 s
Thus, when the mass of the cart changes, the time to travel at 4.6 m/s is 28.11 s.
