i think it's C thx correct me if wrong
Answer:
c. Case iii
Explanation:
the ball will experience the largest change in case iii
Answer:
LAW 1 : For a given metal and frequency, the number of photoelectrons emitted is directly proportional to the intensity of the incident radiation.
---------------------------------------------
LAW 2: For a given metal, there exists a certain frequency below which the photoelectric emission does not take place. This frequency is called threshold frequency.
-----------------------------------------------
LAW 3: For a frequency greater than the threshold frequency, the kinetic energy of photoelectrons is dependent upon frequency or wavelength but not on the intensity of light.
-----------------------------------------------
LAW 4: Photoelectric emission is an instantaneous process. The time lag between incidence of radiations and emission of electron is 10^-9 seconds.
Explanation:
Answer with Explanation:
We are given that


Spring constant,

a.Speed of ham before collision

Collision is inelastic
According to law of conservation of momentum



Kinetic energy of masses=Spring potential energy at maximum distance



Substitute the values

1 m=100 cm
b.Time period,

It should be answer choice b
