Answer:
V = 331.13 mL of 50 by mass NO3 solution
Explanation:
∴ δ sln = 2.00 g/mL
∴ %m HNO3 = 50% = ( mass HNO3 / mass sln ) × 100
∴ V required sln = 500 mL
∴ δ HNO3 = 1.51 g/mL.......from literature
⇒ V sln = mass sln / δ sln = 500 mL
⇒ mass sln = (500 mL )×( 2 g/mL ) = 1000 g sln
⇒ mass HNO3 = ( 0.5 )×(1000 g) = 500 g HNO3
⇒ V HNO3 = ( 500 g HNO3 )×(ml HNO3/1.51 g ) = 331.13 mL

Option A an E.
Explanation:
Energy can be described as the capability to do work. It is what has to be transferred to an object in order to get this object to do work. Energy can be in various forms such as heat energy, kinetic, potential, electrical, chemical, nuclear etc.
It takes energy to do quite a number of things, from cooking food to driving and also in engaging in exercises.
Answer:
The smallest possible inside length of the tank is 
m.
Explanation:
As we know that
Thus, volume of 
liter tank is also equal to 
cubic meter
The volume of a cube is equal to 
, where, x is the length of the side of the cube
With the give condition,
Solving the above equation, we get -
The smallest possible inside length of the tank is m.
