No because an atom consists of <u>two</u> main parts <em>and</em> <u>three</u> subatomic particles - protons, neutrons, electrons. Each one is smaller than an atom, therefore they are subatomic particles. An atom only requires protons and electrons to be an atom - e.g. Hydrogen has 1 proton and 1 electron. Neutrons do not affect the overall charge of the atom, and only increase the atomic mass.
Kinetic energy = (1/2) (mass) (speed)²
Kinetic energy = (1/2) (6.35 kg) (6.0 m/s)²
Kinetic energy = (3.175 kg) (36 m²/s²)
Kinetic energy = (3.175 · 36) (kg-m²/s²)
1 kg-m²/s² = 1 "Joule"
<em>Kinetic energy = 114.3 Joules</em>
Answer:
A2/A1 = 9
V2/V1 = 27
Explanation:
Area of Sphere 1; A1 = 4πr²
Volume of Sphere 1; V1 = (4/3)πr³
Area of Sphere 2; A2 = 4π(3r)² = 9*4πr²
Volume of Sphere 2; V2 = (4/3)π(3r)³ = 27*(4/3)πr³
Thus;
A2/A1 = 9*4πr²/4πr² = 9
V2/V1 = [27*(4/3)πr³]/[(4/3)πr³] = 27
Answer:
acid rain raises the acidity of the water
Explanation:
this is because acid rain mostly contains sulphurdioxide more then carbon components.
