M1 v1 = (m1 + m2)v2.
All of the exponents should be lowered to the bottom right of the letters.
The answer for the question is c
Answer:
The lowest possible frequency of sound is 971.4 Hz.
Explanation:
Given that,
Distance between loudspeakers = 2.00 m
Height = 5.50 m
Sound speed = 340 m/s
We need to calculate the distance
Using Pythagorean theorem
We need to calculate the path difference
Using formula of path difference
Put the value into the formula
We need to calculate the lowest possible frequency of sound
Using formula of frequency
Put the value into the formula
Hence, The lowest possible frequency of sound is 971.4 Hz.
Kinectic Energy=1/2(mass)(velocity)^2 so 1.2=1/2(.0012)(position/2) so it travels 4000 m. Not sure how it is 293.2 ft
