Answer:
It becomes a giant or supergiant.
Explanation:
Once all the hydrogen supply is gone, fusion of hydrogen into helium stops. The core starts to contract and liberates energy, which heats the superior layer until it becomes hot enough to start the fusion of hydrogen into helium.
 
        
             
        
        
        
The number of electrons is equal to the number of protons.
        
             
        
        
        
Answer:
0.00016 kg
Explanation:  
Given: 
Power = P = 1.2 × 10⁹ Watts
Power =  work done / Time 
efficiency = 0.30
Input power = 1.2 × 10⁹ / 0.30 =  4  × 10⁹ W
Energy =  4  × 10⁹ x 60 x 60 = 1.44 x 10¹³ joules 
E = m c² , where c is the speed of light and m is the mass.
⇒ mass = m = E / c²  = (1.44 x 10¹³) / (3 × 10⁸ )² 
                                    = 0.00016 kg 
 
        
             
        
        
        
The mass of this bag of cement in S.I. units (kg) is equal to 0.062 kilograms.
<u>Given the following data:</u>
- Mass of cement = 62 grams.
To calculate the mass of this bag of cement in S.I. units (kg):
<h3>How to convert to 
S.I. units.</h3>
In Science, kilograms (kg) is the standard unit of measurement or S.I. units of the mass of a physical object. Thus, we would convert the value of the mass of this bag of cement in grams to kilograms (kg) as follows:
<u>Conversion:</u>
1000 grams = 1 kilograms.
62 grams = X kilograms.
Cross-multiplying, we have:
X = 
X = 0.062 kilograms.
