1.In the Compton effect, an X-ray photon of wavelength 0.23 nm is incident on a stationary electron. Upon collision with the electron, the scattered X-ray photon continues to travel in the same direction as the incident photon. 1.What is the wavelength λ' of the scattered photon? λ' = 2.A particle (m = 3.7 × 10-28 kg) starting from rest, experiences an acceleration of 2.4 × 107 m/s2 for 5.0 s. What is its de Broglie wavelength λ at the end...

A survey asked, "How many tattoos do you currently have on your body?" Of the 1211 males surveyed, 193 responded that they had at least one tattoo. Of the 1089 females surveyed, 147 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let P, represent the...
