Question

A certain rifle bullet has a mass of 6.93 g. Calculate the de Broglie wavelength of the bullet traveling at 1913 miles per hour. Consult the table of physical constants as needed.

?=_____m

Answer 1

Ans: Given data: Mass of the bullet ma 6.939 = 0.00693kg velocity of the bullet v = 1913 miles per hour firstly, conversion of miles per hour (milh) to meters per second (m/s) conversion factor limi = 1609.34m In = 36005 1913 x 1609.347 1913 mi in 2 =855.18 mis 36005 de Broglie wavelength of the bullet x = h his plancks constant (6.626x1034 kg m75) 6.626810 34 kg m 5 = 0.00693kg X855, 18 mis -34 21.118 X10 m
