So we want to know in which series would the emitted light belong if the electron in a hydrogen atom would go from the energy level n=5 to n=1. The correct answer is Lyman series. Complete Lyman series is from energy level n=6 to n=1. All of the wavelengths in the Lyman series are in the ultraviolet part of the electromagnetic spectrum.
An electric field is an electric property associated with each point in space when charge is present in any form.
Answer:
Second projectile is 1.4 times faster than first projectile.
Explanation:
By linear momentum conservation
Pi = Pf
m x U + M x 0 = (m + M) x V

Now Since this projectile + pendulum system rises to height 'h', So using energy conservation:
KEi + PEi = KEf + PEf
PEi = 0, at reference point
KEf = 0, Speed of system zero at height 'h'

PEf = (m + M) g h
So,


So from above value of V
Initial velocity of projectile =U

Now Since mass of projectile and pendulum are constant, So Initial velocity of projectile is proportional to the square root of height swung by pendulum.
Which means



U₂ = 1.41 U₁
Therefore we can say that ,Second projectile is 1.4 times faster than first projectile.
