The answer should be A. Because the energy in gasoline is called chemical. When burned it is heat, Then to power a vehicle, it is mechanical energy. But I don't know whether the question wants to mean that the energy in the gasoline will not convert totally to the heat, so it will lose. But if think like this, when heat energy transform to mechanical, it will lose again. So I think the answer is A.
Answer:
79.8g/dm³
Explanation:
As you can see, the solution in the problem contains 0.5 moles of copper sulfate per dm³. To solve this question we must convert these moles to grams using its molar mass (Molar mass CuSO4 = 159.609g/mol) as follows:
0.5mol CuSO4/dm³ * (159.609g/mol) =
<h3>79.8g/dm³</h3>
Answer:
The correct statement should be The energies of electron are <em>quantized</em> when <em>they are bounded to an atom.</em>
In Quantum Mechanics The term Quantization used to measure the physical entities having certain discrete value. When we say energies of electron are <em>quantized</em> <em>that means it have some specific values</em> that are allowed, that is not continuous range of values.

Answer:
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Explanation:
Diameter of the cylindrical tube = d = 4.5 cm
r = d/2 ,r = 2.25 cm
Height of the cylindrical tube = h = 13.5 cm
Volume of the cylinder = V = 
The cylindrical tube can hold 0.215 cubic decimeters of blood.
