Because the nucleus is made up of positively charged protons and neutrally charged neutrons, and no negatively charged particles, the charge of the nucleus will always be equal to the sum of the charges of its protons. A simpler way to say it is because each proton has a +1 charge, the charge of the nucleus will be the same as the number of protons in it.
        
             
        
        
        
Answer:
R = 9.85 ohm , r = 0.85 ohm
Explanation:
Let the two resistances by r and R. 
when they are connected in series:
V = 12 V 
i = 1.12 A
The equivalent resistance when they are connected in series is 
Rs = r + R 
So, By using Ohm's law
V = i Rs
Rs = V / i = 12 / 1.12 = 10.7 ohm 
R + r = 10.7 ohm    .... (1)
When they are connected in parallel:
V = 12 V 
i = 9.39 A
The equivalent resistance when they are connected in parallel

So, By using Ohm's law
V = i Rp
Rp = V / i = 12 / 9.39 = 1.28 ohm 
 .... (2)
    .... (2) 
by substituting the value of R + r from equation (1) in equation (2), we get 
r R = 8.36 ..... (3)

 ..... (4)
 ..... (4)
By solvng equation (1) and (4), we get 
R = 9.85 ohm , r = 0.85 ohm
 
        
             
        
        
        
I thinks its He uses proof to show the evidence is relevant. But im not totally positive on it hope this helps
        
                    
             
        
        
        
150*4=600
So the answer is 600
        
             
        
        
        
Answer:
Ozone layer in the upper atmosphere filters most of the harmful radiations of shorter wavelength. It actually absorbs the hazardous radiations like ultraviolet, gamma rays, x- rays and most of all those having shorter wavelength then the visible light. That's how the earth's atmosphere protects life on earth. But unfortunately, climate change and global warming is causing the depletion of ozone layer which is causing skin related diseases and harming not only the human life but also the plants and animals.
