It can be described as a constant variation
Answer:
The direction is due south
Explanation:
From the question we are told that
The energy of the electron is 
The earths magnetic field is 
Generally the force on the electron is perpendicular to the velocity of the elecrton and the magnetic field and this is mathematically reresented as
On the first uploaded image is an illustration of the movement of the electron
Looking at the diagram we can see that in terms of direction the magnetic force is
generally i cross k = -j
so the equation above becomes
This show that the direction is towards the south
The force is 2.0 N east
Explanation:
The impulse exerted by a force is defined as the product between the force itself and the time interval during which the force is applied. Mathematically, it is equal to the change in momentum experienced by the object on which the force is acting:
Where
I is the impulse
F is the force
is the time interval during which the force is applied
is the change in momentum
In this problem,
is the time interval
(east) is the impulse
Therefore, the magnitude of the force is
And the direction is the same as the impulse (east).

Answer:
6 climate regions are Mediterranean, Polar, Tropical, Temperate, Arid and Tundra.
Explanation:
There are six main climate regions in the world. These regions distinguished from one another on the basis of climate that exists there. Above mentioned climates are described shortly as follows:
Mediterranean: This region is the region surrounding the Mediterranean sea, Southern California and Southern America. The climate in this region is hot and dry in summer whereas mild winters are there in this region.
Polar: This region is on the South Pole, near the side of Greenland. The climate in this region is very cold and chilled.
Tropical: This region consists of jungles of South America, Africa, some parts of Asia and the islands of Pacific. The climate of this region is Hot. Due to heavy rainfalls in this area, the area is also wet.
Temperate: North America, Europe and Northern Asia is included in this region. The climate is mild hot in summers and cold in winters.
Arid: This region consists of deserts of Africa, Asia, US and Australia. The climate is very hot throughout the year.
Tundra: This region consists of the mountain tops of America, Asia and Greenland. The climate is extremely cold in such regions throughout the year.
