As per Newton's II law we know that
here for the first case we know that
m = 3 kg
now we will have
now for other case we will have
m = 6 kg
now we have
Kinetic Energy is calculated by KE= 1/2mv2
When an object is above the earth surface gravitational potential energy
i hope this helped :)
Answer:
the answer to the question is calcium
Explanation:
It is given that,
Initial state of electron,
Final state of electron,
The wavelength of the excited electron is given by :
Where
R is Rydberg's constant
or
Let f is the frequency of the observed photon. It is given by :
Hence, this is the required solution.
