Answer:
The smallest separation distance between the speakers is 0.71 m.
Explanation:
Given that,
Two speakers, one directly behind the other, are each generating a 240-Hz sound wave, f = 240 Hz
Let the speed of sound is 343 m/s in air. The speed of sound is given by the formula as :
To produce destructive interference at a listener standing in front of them,
So, the smallest separation distance between the speakers is 0.71 m. Hence, this is the required solution.
Explanation:
Below is an attachment containing the solution.
Answer:
can you please elaborate the question
Explanation:
Answer:
F, F, f (if I'm understanding the question correctly)
Explanation:
Phenotypes are the physical trait shown. In FF, Ff, ff a capital letter means that the gene is dominant and therefore always shows when paired with either another of itself or a recessive (lowercase). So, for FF, you see F as the phenotype shown, and for Ff, you see F as the phenotype because F is dominant over the recessive f. In ff, however, since you have two recessives, only then can you see f as the phenotype because you have no dominant traits.
Answer:
1.2 m/s^2
Explanation:
I will ignore gravity and friction....and will choose 25 N as UP and 40 N to Left (see diagram)
Resultant force: R^2 = 25^2 + 40^2 R = sqrt(2225)=47 N
F = ma
F/m = a
47 N / 40 kg = a = 1.2 m/s^2
