Answer:
Infrasound
but the longer the wavelength of a soundwave, the more it diffracts
Explanation:
Answer:
The man's total displacement is equal to 0.
Explanation:
Given that,
A man ran a 5 mile race. The race looped around a city park and back to the starting line.
We need to find the total displacement of the man.
We know that,
Displacement = shortest path covered
Also,
Displacement = final position - initial position
As it reaches back to its starting line, it means, the displacement is equal to 0.
Hence, the man's total displacement is equal to 0.
(a) Amplitude=1.5 m
Amplitude is the maximum distance from the mean (zero disturbance) position.Here amplitude= 1.5 m
(b) wavelength= 2 m
Wavelength is the length of one complete wave or distance traveled by a wave in a time equal to Time Period. Here wavelength= 2 m
(c) Frequency=7.5 Hz
using equation for wave velocity V= f λ
15= f (2)
f=7.5 Hz
so frequency=7.5 Hz
(d) Time period= 0.133 s
Time period= T= 1/f
T= 1/7.5
T=0.133 s
so time period=0.133 s
Answer:
In its most general sense, a <u>picture</u> is a visual representation of something, especially in the form of a painting, drawing, photograph, or the like. A picture can also refer to a mental image, among other senses.
