Question

Determine the velocity of a marble (m = 8.66 g) with a wavelength of 3.46 × 10-33m.a.45.2 m/sb.11.3 m/sc.22.1 m/sd.38.8 m/se.52.9 m/s

Answer 1

Answer:

Velocity = 22.11 m/s

Explanation:

Using the equation;

λ = h / mv;

where  

λ = wavelength ( 3.46 x 10^-33 )  

m = mass of the marble ( 8.66 g )  

v = velocity ( we gotta find out )  

h = planck's constant ( 6.626 * 10^-34 )  

Making v the subject of the formula;

V = h /mλ

  =(6.626 x 10^-34 ) / 0.00866 ( 3.46 x 10^-33 )  

  = 22.1135

≈ 22.11 m/s
