Hello, love! The answer is True, or T, on Edge2020.
Hope this helped!
~ V.
Wavelength = c/f.
Wavelength =0.5km
I believe the answer your looking for is A. Flammability. Because flammability is a chemical property, not a physical one. Hope this helps :)
Constructive interference in performance halls and the elimination of echoes are reasons why choir concerts better in performance halls than in gymnasiums.
<h3>What is constructive interference?</h3>
Constructive interference is a phenomenon which occurs when two waves travelling in same direction and which are in phase add up together to produce a wave of greater amplitude.
Constructive interference occurs in performance halls while destructive interference occurs in gymnasiums.
Also in performance halls, echoes are minimized due to the padded walls and the curtains while echoes which disturb choir concerts occur in gymnasiums.
Therefore, choir concerts better in performance halls than in gymnasiums because of constructive interference in performance halls and the elimination of echoes.

<span>m1 = 5g = 0.005kg
v1 = 0
m2 = 1.0 x 10^-7g = 1.0x10^-10kg
v2 = 7.5
v3 = ?
looks like you did the formula correctly
m1v1 + m2v2 = (m1+m2)v3
0 + m2v2 = (m1+m2)v3
m2v2 / (m1+m2) = v3
(1.0x10^-10)(7.5) / (0.005 + 1.0x10^-10) = v3
1.5x10^-7 = v3
However, it said the bee gets hit by 1000 pollen grains, so I would guess you have to multiply 1.0 x 10^-10 by 1000 first, unless the total mass of the 1000 grains really is 1.0 x 10^-10.</span>
