Answer:
Highest energy will be equal to 
Explanation:
Charged on doubly ionized helium atom 
It is accelerated with maximum voltage of 3 MV
So voltage 
Now energy is given by 
So highest energy will be equal to 
Answer:
0.693 (you can round it up if you want to)
Explanation:
Density= mass ÷ volume
54.2 ÷ 78.1 = 0.693
I hope this helped☺
Density = mass/volume
D = 40/80 = 0.5g
D= 0.5g
Answer: The layers are ordered by density, with the least dense layer on top, and the densest layer on the bottom.
