Answer:
The maximum velocity is 0.489 m/s
Explanation:
Maximum velocity (v) = angular velocity (w) × radius (r)
w = 33.33 rpm = 33.33×0.1047 = 3.4897 rad/s
r = 14 cm = 14/100 = 0.14 m
v = 3.4897×0.14 = 0.489 m/s
They are all coverd in water 24/7 they never clear up
D is the wrong answer. New information does often completely change the theory. Its hard to change something and leave the major theory intact.
Answer:
"The wavelengths are the same for both. The width of slit 1 is larger than the width of slit 2."
Explanation:
The full question has not been provided, so I just copied this into the web and found this answer and explanation on quizlet:
"The wavelengths are the same for both. The width of slit 1 is larger than the width of slit 2.
D sin θ = m λ
if the wavelengths are the same, then if the angle is smaller, the slit width must be larger. The top photo shows a pattern that is more closely spaced. That means the angle is smaller. The slit width must be larger."
This answer/explanation should be correct, as we are looking at bright fringes and the formula being used corresponds to the parameters of the question.
Hope this helps!
