Explanation:
The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.
G and g
In physics, G and g can be related mathematically as –
\(g=\frac{GM}{R^{2}}\)
Where,
1=g is the acceleration due to the gravity of any massive body measured in m/s2.
2=G is the universal gravitational constant measured in Nm2/kg2.
3=R is the radius of the massive body measured in km.
4=M is the mass of the massive body measured in Kg.
Answer:Energy is absorbed in exact amounts that correspond to differences in energy levels.
Explanation:
According to Bohr's theory, an electron moves from a lower to a higher energy level when it absorbed photon of a given energy. The energy of the photon absorbed must be equal to the energy difference between the higher and lower energy level. Thus energy is absorbed only in discreet amounts that correspond to differences in energy levels. Absorption of energy in discreet amounts is what is meant by the term 'quantization'.
