Answer:
It would be 2.2 if you have to round the five to the one but if your not rounding the number, it'd be 2.1.
Explanation:
Answer:
a
The mass is 
b
The velocity is 
Explanation:
From the question we are told that
The speed of the protons is 
The mass of the protons is 
The speed of the rebounding protons are 
The negative sign shows that it is moving in the opposite direction
Now according to the law of energy conservation mass of one nucleus of the unknown element. is mathematically represented as
Where
is the mass of a single proton
So substituting values


The mass of on proton is 
So 

Now according to the law of linear momentum conservation the speed of the unknown nucleus immediately after such a collision is mathematically evaluated as

Now
because before collision the the nucleus was at rest
So

=> 
Recall that 
So

=> 
substituting values


BecausE the first 'a' is used with a 'u' making a "ahh" sound
The second 'a' isn't paired with any other vowels so it's sound is a strong A sound
And the 'a' at the end is paired with an 'i' in front of it making an "ee-uhh" sound
plz rate me lol i tried <3
The answer is D. Electrical energy can be transformed into both heat and light.
