Answer:
f = 2858.33 Hz
Explanation:
given,
distance between speaker (A) and the person = 2.34 m
Distance between speaker (B) and the person is AB =
=
= 2.46 m
path difference d = BP - AP
= 2.46 - 2.34 m
= 0.12 m
now, λ = 0.12
speed of sound = 343 m/s
f = 2858.33 Hz
the lowest frequency that will produce constructive interference is equal to
f = 2858.33 Hz
Answer:
I believe whale fossils were found.
The given question is incomplete. The complete question is attached with an image below.
Explanation:
Mass flow rate through region A will be calculated as follows.
Rate = 
= 
= 
= 
Therefore, we can conclude that the mass flow rate through region A is .
"Non-Living" things are known as "Abiotic factor" in the ecosystem.
In short, Your Answer would be: Option A) The Water

Answer:
The bystander will hear a frequency of 931.18 Hz.
Explanation:
let V = 39.5 m/s be velocity of the police car and Fs be the frequency a siren of the police car emits. let v = 0 m/s be the velocity of the bystander and Vs = 340 m/s is the velocity of sound in air.
then, we know that the bystander has to hear a higher frequency than the one emitted and the frequency that the bystander hears is given by the doppler relation:
Fo = [(Vs)/(Vs - V)]×Fs
= [(Vs)/(Vs - V)]×Fs
= [(340)/(340 - 39.5)]×(823)
= 931.18 Hz
Therefore, the bystander will hear a frequency of 931.18 Hz.
