The particles will move up and down over small areas.
Option B.
<u>Explanation:</u>
The type of the wave that has been discussed in the question is the transverse kind of wave. The transverse kind of wave are the waves where the particle motion is the perpendicular to the motion of the wave.
In the transverse kind of wave the which is a moving kind of a wave where the oscillations are perpendicular to the direction of the movement of the wave.
Since hex means 6 from Greek, the answer is D) SF6
The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.
<h3>Force on the charge</h3>
The force on the charge is calculated as follows;
F = k(q1q2)/r²
where;
- r is the distance between the charges = 2 m - 1m = 1m
F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²
F = 1.8 x 10⁻⁸ N
Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

Under the assumption that the three rocks are dropped from the same height, they will hit the ground at the same speed. The gravity of Earth is virtually the same for any object that is small compared to the size of the Earth. The acceleration will change with the distance from the Earth, but this change is so small for the range of heights we work with (consider the range of heights from sea level to the tip of Mount Everest) that we can take the average value and assume it to be constant. This constant value of acceleration due to Earth's gravity is 9.80665m/s²
Because the objects fall under the same constant acceleration, they will hit the ground at the same speed.
