(a) What is its momentum? _____ kg·m/s (b) What is its speed? _____ m/s (c) Through what voltage difference does it need to be accelerated to reach this speed? _____ V (d) What's the speed of a 50 kg person having a de Broglie wavelength of λ = 4.4e-38 m? _____ m/s
1. (A) Find the de Broglie wavelength (in nm) associated with an electron that is moving with a velocity of 2310 km/s. The electron rest mass is 9.11 x 10-31 kg. Note, electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms. (B) A baseball weighs 220 g. Top speed for a professional pitcher is about 100 mph when he throws a fast ball. Find...
