It think it has exactly 9
Answer:
Two compounds.
Explanation:
If you have two peaks in your gas chromatograph, this means that you have two compounds.
The gas chromatograph is an instrument that helps identify how many compounds a substance has by observing its behavior against a solid medium through adsorption and the velocity of each compound in it.
Answer:
gamma ray
Explanation:
Gamma emission results in the release of energy without any apparent change in mass or nuclear charge.
Properties of Gamma radiations:
Gamma radiations are high energy radiations having no mass.
These radiations are travel at the speed of light.
Gamma radiations can penetrate into the many materials.
These radiations are also used to treat the cancer.
Lead is used for the protection against gamma radiations because of its high molecular density.
The lead apron are used by the person when treated with gamma radiations.
Lead shields are also used in the wall, windows and doors of the room where gamma radiations are treated, in-order to protect the surroundings.
Multiply velocity and time and you get 0.644 km, but remember that displacement has a direction and so does velocity, so because velocity is positive in the direction that the falcon is going you have a positive displacement.
