4. The teacher, in her Health class mentions that there are several types of periodontal diseases, one of them is the one that causes inflammation and infection of the ligaments and bones that support the teeth, corresponds to:
(1 point)
Gingivitis
Periodontitis
Cavities
Oral herpes
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
