Answer:
51.82
Explanation:
First of all, let's convert both vectors to cartesian coordinates:
Va = 36 < 53° = (36*cos(53), 36*sin(53))
Va = (21.67, 28.75)
Vb = 47 < 157° = (47*cos(157), 47*sin(157))
Vb = (-43.26, 18.36)
The sum of both vectors will be:
Va+Vb = (-21.59, 47.11) Now we will calculate the module of this vector:

On Titan, the largest moon of of Saturn did the Cassini-Huygens probe land in 2004.
To find the answer, we have to know more about the Cassini-Huygens Mission.
<h3>
What is Cassini-Huygens mission?</h3>
- Before arriving at its final destination of Saturn in 2004 and beginning a series of flybys of Saturn's moons, the spacecraft contributed to studies of Jupiter for six months in 2000.
- In the same year, it launched the Huygens probe to explore Titan's atmosphere and surface makeup on Saturn's moon.
- During its second extended mission, Cassini sailed between the rings, entered the planet's atmosphere, and obtained the first measurements of a whole seasonal period for Saturn and its moons.
Thus, we can conclude that, on Titan, the largest moon of of Saturn did the Cassini-Huygens probe land in 2004.

Covalent bonding is a type of chemical bonding wherein there is a sharing of electrons to achieve chemical stability or the octet rule. For instance, the chlorine atom with one unpaired electron shares an electron to sodium to become stable. In the given examples, the situation that portrays covalent bonding is when Chlorine accepts 1 electron from calcium to form a stable bond.
