The disturbance does not have a specific motions
Answer:
The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
Explanation:
Given:
Δy = d
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2(g)(d)
v = √(2gd)
If we double d:
√(2g (2d))
√(4gd)
Compared to the first velocity:
√(4gd) / √(2gd)
√2
So the new velocity is √2 greater than the first velocity.
√2 v
Answer:
Part a)
Frequency of sound is 130 Hz
Part b)
Wavelength of the sound is 2.65 m
Explanation:
Part a)
Frequency of source of the sound is same as the frequency of the sound
Here we know that motion of hammer is back and fourth with frequency
f = 130 cycles per second
so frequency of sound is same as frequency of hammer motion
so we have
Part b)
As we know that the speed of sound is
v = 345 m/s
We know that the frequency of sound is
f = 130 Hz
now the wavelength is given as
Newtons are used to measure force
