Asupervisor spends a day inspecting a nuclear plant for potential radiation leaks. she has to move throughout the plant inspecting all the equipment and machinery. she needs to take two different radiation detection devices to ensure her safety and to find radiation leaks. she needs the results immediately. which two devices would be the best choices for the task? geiger counter and scintillation counter geiger counter and cloud chamber cloud chamber and scintillation counter film badge and scintillation counter

Geiger counter and scintillation counter

Explanation:

The Geiger counter was invented by Hans Geiger in 1908 to measure the levels of radiation in bodies and the environment, so it is one of the indispensable equipment for the inspector to detect radiation leaks in a nuclear power plant. It contains a tube with argon, which ionizes by being crossed by alpha and beta particles of radiation, closing the electric circuit and triggering the counter.

Similarly, a scintillation detector is an apparatus used to detect ionizing radiation. When something in the environment has been reached by radiation, this detector emits a small ray of light, indicating the radiation contamination.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
