Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn't get fertilized, that lining is released from the body as blood through the vagina. This monthly process is called menstruation or a period.
Answer:2.21 x 10^-7 m
Explanation:
From the question we know that,
Phi = 9.05 x 10^-19 J
Now with Vo being the threshold frequency and h being Plancks constant, then the threshold (i.e. MINIMUM) frequency required to ionize the metal is:
Vo = 9.05 x 10^-19 / 6.626 x 10^34 J.s
= 1.36 x 10^15 s^1
The MAXIMUM wavelength this corresponds to is
Landa = C / Vo = 3 x 10^8 / 1.36 x 10^15
Wavelength = 2.21 x 10^-7m
= 2.21 x 10^-7 nm
