A sprinter must average 24.0 mi/h to win a 100-m dash in 9.30 s. What is his wavelength at this speed if his mass is 84.5 kg? Group of answer choices 7.29 × 10–37 m 3.59 × 10–37 m 5.08 × 10–30 m 1.34 × 10–30 m

An electron, with a mass of 9.109 x 10-28 g is emitted from an atom at a velocity of 2.74 x 109 m/s.  What is its de Broglie wavelength, in meters?  h = 6.626 x 10-34 kg m2/s

if the energy of a photon is 7.44 x 10^-18 hz what is its wavelength in nm? (nanometers)

A hydrogen atom undergoes a transition from the n = 8 level. Calculate the shortest possible wavelength (in units of nm) of electromagnetic radiation emitted by the hydrogen atom. Your answer must be in units of nanometers. c = v) E = hv E = -(Rµ/n²) X= (h/mu) AE = -RH ((1/n;3) – (1/n²)] (1/A) = (Rµ/hc) [(1/n}) – (1/n²)] %3D c = 2.9979 x 108 m · s-1 h = 6.6260 x 10-34 j.s RH = 2.1798 x 10–18, 1 pm 1x 10 12 m 1 nm = 1x 10-9 m 1 Á = 1x 10-10 m %3D %3D NA = 6.0221 x 1023/ mol
