when we need to represent the magnetic field in a specific region where it is given that magnetic field lines are perpendicular to the plane and going inside the plane then we always use the concept of representation by "X"
here this symbol represents that field lines are going into the plane
it is also the uniform magnetic field always
so the correct answer would be
<u>Magnetic Field</u>
Answer:
Polar areas
Explanation:
From what I know Arctic, Antarctic, and polar air masses are cold. Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm).
- With the options you gave, you can immeditaly elimate 1. tropical areas and 2. an area where its summertime.
- Your then left with two options 1. an area where its wintertime and 2. polar areas
I then concluded that cold air masses tend to originate from POLAR AREAS.
Definitely not the last 2. My bet is on the first option. If it is wrong don't hit me please...
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun at it travels through its year long pat around the sun.
Direction of motion is one part of a complete description of velocity.
So if the direction of motion changes, that's a <em>change of velocity</em>, even if the speed didn't change.
The change of direction is called "an acceleration", even if the speed didn't change.
