A relationship exists and the numbers cause one another can be said about two numbers that have either a positive or negative correlation
Option : C
<u>Explanation:</u>
When two numbers have positive correlation, they move in the same direction. If the first variable increases, the second one also increases and if one variable decreases the other one also decreases.If the two numbers have negative correlation, the two numbers move in opposite directions.
A relationship exists between two numbers and the number cause one another. A correlation means that changing one variable affects the other. Correlation among variables need not necessarily imply causation. Positive correlations are mostly used in Finance and stock markets.
Answer:
The medium is what the ray is traveling through.
Explanation:
"Medium" is just another word for the space surrounding the ray. For example, if a ray of light is traveling through water, water would be the medium the light ray is traveling through.
Answer:
A solenoid is a device comprised of a coil of wire, the housing and a moveable plunger (armature). When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in. More simply, a solenoid converts electrical energy into mechanical work.
Explanation:
The coil is made of many turns of tightly wound copper wire. When an electrical current flows through this wire, a strong magnetic field/flux is created.
The housing, usually made of iron or steel, surrounds the coil concentrating the magnetic field generated by the coil.
The plunger is attracted to the stop through the concentration of the magnetic field providing the mechanical force to do work.
An electric field has both magnitude and direction.
I don't think that's one of the first 3 choices.
That kind of depends on the motion of the object. The graph is drawn in order
to illustrate the nature of the object's motion, and they're all different. If they
were all the same, then graphs would be boring, and nobody would draw them
anymore.
