Answer:
a) f = 809.5 Hz
, b) f = 1619 Hz
Explanation:
The condition for destructive interference from the speakers is
Δr / lam = Ф / 2π
λ = Δr 2π / π
We substitute
λ = 0.21 2 π/π
Lam = 0.42 m
Now let's use the ratio of the speed of sound and the wavelength and the frequency
v = λ f
f = v /λ
f = 340 / 0.42
f = 809.5 Hz
b) in this case the intensity is maximum
Lam = Δr 2π / 2π
Lam = 0.21 m
fF= v / lam
f = 340 / 0.21
f = 1619 Hz
Answer: I actually need the same answer
Explanation:
Answer:
An object's ability to do work is measured by its mechanical energy, or the sum the object's kinetic energy and potential energy. Mechanical energy is due to the position or movement of an object. The formula for mechanical energy is mechanical energy = kinetic energy + potential energy.
