Answer:
(a) 1852259
(b) 489085.47 pound
Explanation:
We have given auditorium measures 35 m×30 m×5 m
We know that 1 meter = 3.28 feet
So the measure of auditorium = 35×3.28 feet ×30×3.28 feet× 5×3.28 feet
(a) So the volume of the auditorium 
Density is given as
(b) weight of air = volume × density 
We know that 1 kg = 2.20 pound
So 222311.577 kg =222311.577×2.20=489085.47 pound
-45N because you add the side together and make it equal 0

Answer:
Maximum speed ( v ) = 10.4 m/s (Approx)
Explanation:
Given:
Amplitude A = 15.0 cm = 0.15 m
Frequency f = 11.0 cycles/s (Hz)
Find:
Maximum speed ( v )
Computation:
Angular frequency = 2πf
Angular frequency = 2π(11)
Angular frequency = 69.14
Maximum speed ( v ) = WA
Maximum speed ( v ) = 69.14 x 0.15
Maximum speed ( v ) = 10.371
Maximum speed ( v ) = 10.4 m/s (Approx)
