Answer:
q = 2,95 10-6 C
Explanation:
The magnetic force on a particle is described by the equation
F = q v x B
Where bold indicate vectors
Let's make the vector product
vxB =![\left[\begin{array}{ccc}i&j&k\\-3&4&12\\0&0&-0.13\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Di%26j%26k%5C%5C-3%264%2612%5C%5C0%260%26-0.13%5Cend%7Barray%7D%5Cright%5D)
v x B = 1.20 106 [i ^ (4 0.130) - j ^ (3 0.130)]
vx B = 1.20 106 [0.52 i ^ - 0.39j ^]
As they give us the force module, let's use Pythagoras' theorem,
|v xB | =1.20 10⁶ √( 0.52² + 0.39²)
|v x B| = 1.20 10⁶ 0.65
v xB = 0.78 10⁶
Let's replace and calculate
2.30 = q 0.78 10⁶
q = 2.3 / 0.78 106
q = 2,95 10-6 C
<span>So the question is what gases form the atmosphere of Uranus. So Uranus and Neptune are classified as "ice giants". They have a similar atmosphere to "gas giants" Saturn and jupiter and Neptunes atmosphere is primarily composed out of hidrogen and helyum. So the correct answer is a.</span>

Explanation:
Distance is a scalar and displacement is a vector
Explanation:
Distance and displacement are two different quantities. Let's review them in detail:
- Distance is a scalar quantity (only a number followed by unit). Distance represents the total length of the path covered by an object during its motion. Therefore, it does not take into account the direction of motion, in its calculation.
- Displacement is a vector quantity, so it has a magnitude, a unit and a direction. Displacement is a vector connecting the initial position to the final position of the motion of an object. Therefore, in its calculation, the direction of motion must be taken into account.
Let's see an example in order to understand distance and displacement better.
Imagine a person moving 5 meters forward and then 2 meters backward. In this case:
- The distance covered by the man is just the total lenght of the path covered, therefore: 5 + 2 = 7 meters
- The displacement of the man is the distance between the initial and final position. Since the man moved 5 m forward and 2 m backward, his final position is 3 meters forward, therefore the displacement is 3 m in the forward direction.
