Answer:
Explanation:
We shall apply the formula of Doppler effect here
F( APPARENT) = F( REAL ) X V/(V + Vs) [ v is velocity of sound and Vs is velocity of source.
415 = 440 X 343/343+Vs
142345 + 415Vs = 150920
415 V₀ = 8575
V₀ = 20.66 m/s.

Wending your way through this question and the list of choices
is like running through a corn-maze on a moonless night with
your eyes closed.
Work = (force) x (distance)
Keeping with the units used In the question ...
Work = (90 pounds) x (4 feet) = 360 foot-pounds .
If you want the work expressed in joules, then you need to convert
pounds and feet to newtons and meters.
(90 pounds) x (4.448 newtons/pound) = 400.32 Newtons
(4 feet) x (1 meter / 3.28084 feet) = 1.219 meters
Work = (force) x (distance)
= (400.32 newtons) x (1.219 meters) = 488.1 joules .
Answer:
Particles vibrate parallel to the direction the sound travels
