Best answer must be false. Because the IMA it doesn't have always stay smaller than the AMA. Hope it helped you!
The correct answer is D. 2200 Hz
Explanation:
The frequency of a wave is measured in hertz (Hz) and refers to how often a wave passes through a point during a specific time. This factor can be calculated if you divide the velocity of the wave by the wavelength (distance between crests) this means f (frequency) = v (velocity) / λ (wavelength).
f (frequency) = 242 m/s (velocity) / 0.11 (wavelegth)
f = 2200 Hz
According to this, the frequency of the wave, in this case, is 2200 Hz
Answer:
No fallacy
Explanation:
The statement that at least 50% of the students at Northern State own an iPod is best categorized as no fallacy.
This statement is very true and consistent with the facts presented in the passage.
A fallacy is a mistaken belief usually based on biased arguments.
Total number of students sampled = 200
Number of iPod owners = 150
Percentage of iPod owners =
x 100
Percentage of iPod owners =
x 100 = 75%
We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.
D: Ptolemy envisioned a geocentric model, while Copernicus envisioned a heliocentric model.
Answer: Force is 4 times lower.
Explanation:
F1=γ*m₁m₂/r²
r*2=2r
F2=γ*m₁m₂/4r₂
F1/F2=4
F2=F1/4
