Answer:
Abby is standing (4.5^2 + 2.3^2)^1/2 from the far speaker
D2 = 5.05 m from the far speaker
The difference in distances from the speakers is
5.05 - 4.5 = .55 m (Let y be wavelength, lambda)
n y = 4.5
(n + 1) y = 5.05 for the speakers to be in phase at smallest wavelength
y = .55 m subtracting equations
f = v / y = 340 / .55 = 618 / sec should be the smallest frequency
10 mph/s because there is 60 seconds in a minute then divide by 6 which is 10.
Explanation:
that's impossible,the radius of the earth can't decrease when the mass doubles!
Answer:
Important enough for someone to ask you to do it.
Explanation:
If someone asked you this question, then it must be important and stuff. This is proven by scientific stuff that no one cares about.
force times gravity (FG) =mass times gravity (mg)
