Question 11 of 29

Gamma radiation is very high energy electromagnetic rays, but its behavior is the same as for all radiation. By the principle of conservation of energy after the radiation is emitted, it must be distributed on a spherical surface which determines the behavior of the inverse of the square.

In this experiment you are measuring the rate of counts by time (C), this must be the dependent variable since it is not controlled by the experimenter and on the other hand it measures the distance (X) this is the independent variable since it is the one that we can control.

To make a graph with this data, the counting rate must be plotted against the inverse of the squared distance (1/R²). On the Y axis the counts per second and the X 1 / R² axis, with this graph a line must be obtained.

Another graph that we can make on double logarithmic paper where the Y axis plotted the counting rate and on the X axis the distance, the slope should give -2.

C == A / R²

Log C = log A -2 log R

With either of the two graphs, the law of the inverse of the square is tested

One step of copper mining requires blasting ore to be able to blasted and extracted from mine.

This process causes harm to the Geosphere (Lithosphere)
In this step, they blast the mines inside the earth. Which causes destruction and harm to the geosphere.
We know that, land comes under Geosphere also known as Lithosphere.

Mercury is used to recover minute pieces of gold that is mixed in soil and sediment. Sometimes Mercury can be lost in this process resulting in widespread contamination of local rivers and lakes.

This causes harm to the Hydrosphere.
The portion of earth covered with water is known as hydrosphere.
Since, The Mercury is getting mixed with the water. It is polluting the water that is the hydrosphere.

Hundreds of tons of rock are unearthed, moved and crushed in mining operation significantly increasing the amount of dust and particulates in the air.

This causes harm to the Atmosphere.
The particles of dust get increased in air and eventually gets mixed and spread everywhere.
The air is getting polluted which means the atmosphere is getting harmed.

Strip mining (also known as mountaintop removal) involves scraping away earth and rocks to get to coal buried near the surface. This often results in the destruction of ecosystems.

This causes harm to the Biosphere.
The biosphere consists of plants and animals. And these plants and animals collectively form a habitat called ecosystem.
When a ecosystem is destroyed, the biosphere is harmed.
