The traveler's total displacement is 53.2 km.
The shortest distance between a particle's starting position and destination is referred to as its displacement vector. Displacement has a distinct physical magnitude than distance. Let's use the motion of a particle making a complete circle as an example. The displacement in this motion is zero, yet the distance traveled is equal to the circle's circumference. The individual displacement vectors are as follows: d1
=22^ikm→d2
= (29.7cos45i29.7sin45) kmd3=104jkm
The traveler's complete disadvantage is,
→d=→d1+→d2+→d3→d
=22^ikM+29.7
cos45^−29.7sin45o) km−10.4^j km→
d=(43^i−31.4^j) km
The magnitude of the total displacement is,
d=√432+31.4/2Km d≈53.2km
The direction is,
θ=tan−1(−31.4/43)
θ=−36.1or 36.1 south of east.

Answer: an element; a compound
A compound is a molecule with at least two kinds of atoms. Since iron is only containing Fe then it shouldn't be a compound.
After iron got rust reaction, it will have oxygen make it become iron oxide. The iron oxide having Fe and O so it is a compound.
Answer:
The reason for phonograph installation is to provide information about humans to interstellar aliens.
Explanation:
Phonographs are archaic forms of gramophone which are able to record and reproduce sound.Phonographs were used in early days in voyagers to help transmit information about humans to nearby alien species in space.
Arboreal
Explanation:
The best term that describes the habitat of bats is arboreal.
The habitat of an organism is its dwelling place in nature. This encompasses the role it plays in the ecosystem.
- Bats spends most of their life time hanging down on trees.
- They are blind flying mammals.
- Animals that lives in trees and trunks are said to be arboreal.
- Other examples are koalas, primates, sloths, spider monkeys, leopards, chameleons etc.
- These animals are adapted for life in tree trunks.
- The have modified body parts that makes them thrive in such habitats.
