We can see it as two movements: one on the north-south axis and one on the west-east axis.
On the north-south Axis, the hiker went 8 km north and 4 km south, so in total the hiker went 4 km north (we can subtract one for the other and the direction remains that which was bigger)
On the west-easth Axis, the hiker went 6 km east and 6 km west, so in total the hiker didn't move on this axis! or, he/she moved but then "came back"
So in total, the hiker only moved4 km north - answer B.

Answer:
They measured their train using their handspan
A lot would happen depends on which perspective you look at it from. Less incoming solar radiation means that there is a greater possibility of the surface temperature of earth reducing. there would be a cooling effect. And it could be major cooling in certain part of the world depending on milankovitch cycles. We know that the amount of light or solar radiation that reaches the earth is unequal in different parts of the world because of the obliquity, eccentricity, and precession of the earth. But, in general you would most likely see a cooling trend around the world and in some parts it would be extreme. In Canada or in the North is general, winters would become even more cooler or colder... winters would become longer perhaps, And summers would 've cooler. on the contrary to what most believe, you would most likely see a decline in precipitation such as snow or rain because this is mostly caused or intensified by warming temperatures. Life would be probably very similar to that of the Pleistocene epoch. how would humans respond to this change... Well most likely they would try to use their tech to control weather because they already do to a smaller proportion.
hope that helps a bit! :)
Answer:
mixture
Explanation:
All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules. Using this fact, matter can be classified into three broad groups: elements, compounds and mixtures. In an element, all the atoms are of the same type. If more than one type of atom is chemically joined, then a compound has been formed. If more than one type of atom or molecule is contained in the same substance, and the particles aren't chemically joined, this is a mixture.
d. lower frequencies and low energy.
Explanation:
Microwaves and infrared waves are lower frequencies and lower energy waves.
They are both non-ionizing radiation.
- Microwaves and infrared waves are both electromagnetic waves.
- They do not require a material medium to be propagated in nature.
- They have little energy because the have very low frequency.
- They also have very long wavelengths.
