Answer:
because when an object approaches the speed of light, it's mass starts to increase exponentially, and would be infinite at the speed of light. It would therefore require MORE than an infinite amount of energy to accelerate even a single electron to the speed of light
 
        
             
        
        
        
Answer:
The true weight of the aluminium is  4.5021 kg
 4.5021 kg
Explanation:
Given data
 = 4.5 kg
 = 4.5 kg
 = 1.29
 = 1.29 
 = 2.7×
 = 2.7× 
The true mass of the aluminium is given by 

Put all the values in above equation we get

 4.5021 kg
 4.5021 kg
Therefore the true weight of the aluminium is  4.5021 kg
 4.5021 kg
