Independent variable: the student chooses to miss class.
dependent variable: in result of the student missing class his grade goes down.
hyposthesis: if the student misses class multiple times, then his grades will go down.
Answer: Option (c) is the correct answer.
Explanation:
When current passes through a wire then a magnetic field is formed. Therefore, when two wires carry current in the same direction then both the wires with have respective magnetic fields in the same direction and their total magnetic field will be large.
But when current between two wires flow in opposite direction then the magnetic field produced will also be in opposite direction. Therefore, both the magnetic fields cancel each other out. Thus, total magnetic field will be small.
As a result, wires which carry current in the opposite direction repel each other.
Your blood is a living part or tissue of your body that composed of liquid and solid part. The liquid part is made of plasma and mineral like, water, salt and protein. While the solid part is composed of red blood cells, white blood cells and also platelets
If all the particles in a material are made up of
several smaller particles, and every larger particle
is identical, is the material a pure substance or
not? Explain your reasoning.
A pure substance is something like a compound and element. This material made of several particles which seem to be two different particles, I believe, is a mixture. So, it is not a pure substance mixtures are made up of more than one particle while compounds (In a fixed ratio, the fusion of two or more than two atoms) and elements are made up of one molecule essentially.
