Police siren is the correct answer. Hope this helps.
Answer:
Explanation:
The magnitude of the electric force on this charged particle A depends upon the following
5. the distance between the point charge Q and the charged particle A
8. the amount of the charge on the point charge Q
9. the magnitude of charge on the charged particle A
The solution for this problem is:
500 revolution per
minute = 8.33rev /s = 2π*8.33 rad /s = 52.36 rad /s
Angular velocity ω = 2π N
Angular acceleration α= (ω2 - ω1) /t
ω2 = 0
α = - ω1/t = -2π N /t
N = 500 rpm = 8.33 r p s.
α = -2π 8.33 /2.6 =- 20 rad/s^2

Answer:
Mark me as brain list plz
Explanation:
Using Bernoulli's Theorem
1/2 V12 +P1/d = 1/2V22 +P2/d
V1 = 17.4
V2 =0
1 /2 V12 = Pressure Difference / d
Where d = Density of air
Pressure Difference =( 1/2 V12) Density of air
Pressure Difference = 369.36
Force = Pressure difference * area = 369.36 *3.5 = 1292.8 N
