People who work around radioactivity wear film badges to monitor the amount of radiation that reaches their bodies. each badge consists of a small piece of photographic film enclosed in a lightproof wrapper. what kind of radiation do these devices monitor, and how can they determine the amount of radiation people receive?

Explained

Explanation:

People who work around radioactivity wear film badges to monitor the amount of radiation that reaches their bodies to prevent themselves from the harmful gamma rays. These film badges monitor gamma rays. Gamma rays are a form of electromagnetic radiation. As a result the greater of the exposure the darker the film will be once produced. So, by measuring the darkness of these films one can easily determine the amount of radiation people receive.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
