Answer:
q₃ = - 13.0935 μC
Explanation:
Given
q₁ = q₂ = +7.67 μC
We use the equation
V = Kq/r
We can apply it as follows
V₁ = K*q₁/r₁ = K*q₁/(√2*L)
V₂ = K*q₂/r₂ = K*q₂/L
V₃ = K*q₃/r₃ = K*q₃/L
Then
V₁ + V₂ + V₃ = 0
⇒ (K*q₁/(√2*L)) + (K*q₂/L) + (K*q₃/L) = 0
⇒ (K/L)*((q₁/√2) + q₂ + q₃) = 0
⇒ (q₁/√2) + q₂ + q₃ = 0
Since q₁ = q₂
⇒ (q₁)((1/√2) + 1) + q₃ = 0
⇒ q₃ = - (q₁)((1/√2) + 1) = +7.67 μC*(1.7071)
⇒ q₃ = - 13.0935 μC

Answer:
The high-pressure region refers to the condition where the cold and dense air sinks and makes the atmosphere stable, forming clear sky or presence of low clouds in the sky.
On the other hand, the low-pressure region refers to the condition where the hot and less dense air rises upward, and with the presence of a sufficient amount of water content in the air, it gives rise t the formation of the clouds and eventually leads to the occurrence of rainfall.
This is how the process of precipitation is related to the high and the low-pressure air, where the low-pressure zone results in precipitation and high-pressure zone results in a clear sky.
Answer: 0.55 m/s
Explanation:
This situation is related to projectile motion (also called parabolic motion), where the main equations are as follows:
(1)
(2)
Where:
is the horizontal displacement of the pencil
is the pencil's initial velocity
since we are told the pencil rolls <u>horizontally</u> before falling
is the time since the pencil falls until it hits the ground
is the initial height of the pencil
is the final height of the pencil (when it finally hits the ground)
is the acceleration due gravity, always acting vertically downwards
Begining with (1):
(3)
(4)
Finding from (2):
