Answer : a quantitative description of kinematics involves using position , time velocity and acceleration to describe the motion.
Explanation : Kinematics are mostly concerned with the geometrically possible motion of an object without consideration of the force and mass involved.
it is used to describe the position of the object , their velocities, time and their acceleration.
we know the equations of motion.
....(I)
....(II)
....(III)
Where, v = velocity
t = time
a = acceleration
s = position , distance

Answer:
Explanation:
We need to find the energy for an electron to jump from n = 1 to n = 4.
The energy in transition from 1 state to another is given by :
The difference in energy for n = 1 to n = 4 is:
So, the required energy is equal to .
