Answer:
The point at which the electrical potential is zero is x = +0.33 m.
Explanation:
By definition the electrical potential is:
Where:
K: is Coulomb's constant = 9x10⁹ N*m²/C²
q: is the charge
r: is the distance
The point at which the electrical potential is zero can be calculated as follows:
(1)
q₁ is the first charge = +3 mC
r₁ is the distance from the point to the first charge
q₂ is the first charge = -6 mC
r₂ is the distance from the point to the second charge
By replacing r₁ = 1 - r₂ into equation (1) we have:
(2)
By solving equation (2) for r₂:
Therefore, the point at which the electrical potential is zero is x = +0.33 m.

The answer is; nodes
A standing wave occurs when two waves with the same properties moving in the opposite direction, in the same media, interfere with one another. Nodes are points where the waves interact destructively causing an appearance of the wave standing still. The opposite of nodes is antinodes where they are points of maximum displacement due to constructive destruction.
Terminal velocity is the point when an accelerating object reaches a constant speed. When an object is in free fall on earth, this happens due to the drag force of the atmosphere that pushes up on the object.
If the earth had no atmosphere, the object would keep accelerating and never reach terminal velocity due to the lack of air drag.
V=f*wavelength
30m/s=f*(0.35m)
f=85.7 Hz
Answer:
The unique sound quality of a clarinet or a violin is caused by the relative intensity of different harmonics in each note.
