Answer:
(a) 0.3778 eV
(b) Ratio = 0.0278
Explanation:
The Bohr's formula for the calculation of the energy of the electron in nth orbit is:
(a) The energy of the electron in n= 6 excited state is:
Ionisation energy is the amount of this energy required to remove the electron. Thus, |E| = 0.3778 eV
(b) For first orbit energy is:
Ratio = 0.0278
Intrusive igneous rocks cool down from magma slowly because they form underneath the surface, that will make them have large crystals.
Extrusive igneous rocks cool down from lava rapidly because they form at the surface, so that will make them have small crystals.
Answer:
It includes earthwork, trenching, wall shafts, tunneling and underground
Explanation:
If the container explodes there is no pressure, becuase all your gas has escaped its container, there for, you ain’t got no gas
Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point
