Free ions. Negative ions have one extra electron, positive ions are missing an electron. Negative ions give up their extra electron easily. I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.
Answer:
Visible, or infrared lights
Using the following formula for linear-motion, the missing variable can be solved:
s = Vi * t + 1/2 (a * t^2)
Where: s = displacement = 29.7 m
Vi = initial velocity = 8.5 m/s
a = acceleration = 9.8
t = time = ?
Substituting:
29.7 = 8.5t + 1/2 (9.8*t^2)
29.7 = 8.5t + 4.9t^2
Dividing both sides by 4.9:
6.06 = 1.73t + t^2
t^2 + 1.73t - 6.06 = 0
(t - 1.74)(t + 3.48) = 0
t = 1.74s
From the above values, the correct answer is 1.74 seconds.
Resident 4 is the correct answer.
Answer:
a 
b 
c 
Explanation:
From the question we are told that
The magnitude of electric dipole moment is 
The electric field is 
The distance between the positive and negative charge center is mathematically evaluated as

Where e is the charge on one electron which has a constant value of 
Substituting values


The maximum torque is mathematically represented as

Here 
This because at maximum the molecule is perpendicular to the field
substituting values


The workdone is mathematically represented as

where
is the potential energy at 180° which is mathematically evaluated as

Where the negative signifies that it is acting against the field
substituting values


and
is the potential energy at 0° which is mathematically evaluated as

substituting values


So ![W = 1.24 *10^{-25} - [-1.24 *10^{-25}]](https://tex.z-dn.net/?f=W%20%3D%20%201.24%20%2A10%5E%7B-25%7D%20-%20%5B-1.24%20%2A10%5E%7B-25%7D%5D)
