Answer:
(a) 0.177 m
(b) 16.491 s
(c) 25 cycles
Explanation:
(a)
Distance between the maximum and the minimum of the wave = 2A ............ Equation 1
Where A = amplitude of the wave.
Given: A = 0.0885 m,
Distance between the maximum and the minimum of the wave = (2×0.0885) m
Distance between the maximum and the minimum of the wave = 0.177 m.
(b)
T = 1/f ...................... Equation 2.
Where T = period, f = frequency.
Given: f = 4.31 Hz
T = 1/4.31
T = 0.23 s.
If 1 cycle pass through the stationary observer for 0.23 s.
Then, 71.7 cycles will pass through the stationary observer for (0.23×71.7) s.
= 16.491 s.
(c)
If 1.21 m contains 1 cycle,
Then, 30.7 m will contain (30.7×1)/1.21
= 25.37 cycles
Approximately 25 cycles.
<span>Newton and Leibniz feuded over who invented calculus. Newton had proabaly come up with the idea eariler, but Leibniz took the spotlight by publishing first. Complicating things were their respecitve home countries, England and France, which had their own rivalry at the time. Further complicating matters was that they discovered different types of calculus, and had different notations. Today, beggining calculus students use methods and notations similar to Leibniz, but Newton's methods come into use in higher level classes.</span>
