Answer:
The electrical potential energy is 0.027 Joules.
Explanation: 
The values from the question are 
charge (q) = 
Electric Field strength (E) = 
Distance from source (d) = 0.030 m
Now the formula for the electrical potential energy (U) is given by 

So now insert the values to find the answer 

On further solving 

 
        
             
        
        
        
That statement is false 
Our subconscious tend to give a strong influence to our behaviours even if we are not feeling it directly. 
For example, let's say that there is a boy that hurt by cats and it's ingrained in his head that cats possess high level of danger to him. Even after that boy grow up, his subsconcious would most likely cause a certain level of paranoia that make him either scared of cats or simply annoyed by seeing them.

Answer:
The atmospheric pressure is  .
.
Explanation:
Given that,
Atmospheric pressure  
     
drop height h'= 27.1 mm
Density of mercury 
We need to calculate the height
Using formula of pressure

Put the value into the formula



We need to calculate the new height




We need to calculate the atmospheric pressure
Using formula of atmospheric pressure

Put the value into the formula


Hence, The atmospheric pressure is  .
.
