OSHA (one part of a Personal Fall Arrest System) requires workers to wear a full-body harness, when they are working on a suspended scaffold more than 10 feet above the working surface, or when they are working in bucket truck or aerial lift.
Mindfulness.
Check out the set on Quizlet named child development ch 8 - that's where I got it.
Hope this helped :)
Solution for the problem:
w = h / p
Where:
Wavelength = w
h = Planck's constant = 6.626e-34J*s
p = momentum = m * v
m = mass = 45.9g (1kg / 1000g) = .0459 kg
v = velocity = 66m/s
p = m * v = .0459 kg * 66m/s = 3.0294 N *s
w = h / p = (6.626e-34J*s) / 3.0294 N *s = 2.76e-34 m
