First I will parallel two of the resistors, creating a net 1 ohm. Then I will series that with the remaining 2-ohm resistor, resulting in 3 ohms.
        
             
        
        
        
A=(vf-vi)/t
a=(50-25)/10
a=2.5m/s^2
        
             
        
        
        
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by  here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
 here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron 
We know that 
Potential well dimension = 
Mass of electron 
So energy required to electron to jump from ground state to 3rd state 



 
        
             
        
        
        
Answer:
Centripetal acceleration is defined as the property of the motion of an object, traversing a circular path. Any object that is moving in a circle and has an acceleration vector pointed towards the center of that circle is known as Centripetal acceleration. ... Centripetal means towards the center.
 
        
                    
             
        
        
        
For the answer to the question above, I the answer is yes, It is <u><em>both </em></u><span><u><em>contaminated and </em></u><u><em>radioactive</em></u></span><u><em> at the same time</em></u>. That's why they keep the water spinning.I hope my answer helped you. Have a nice day!
