Answer:
C. It is radiation leftover from the Big Bang
Answer: 2.67 m/s^2
Explanation:
Centripetal acceleration is defined as v^2/r; in this case, it's 2^2/1.5, which is 2.67.
It typically take longer for a heavier object to slow down therefor, a train will take more time. <span />
Answer:
1.) Frequency F = 890.9 Hz
2.) Wavelength (λ) = 0.893 m
Explanation:
1.) Given that the wavelength = 0.385m
The speed of sound = 343 m / s
To predict the frequency, let us use the formula V = F λ
Where (λ) = wavelength = 0.385m
343 = F × 0.385
F = 343/0.385
F = 890.9 Hz
2.) Given that the frequency = 384Hz
Using the formula again
V = F λ
λ = V/F
Wavelength (λ) = 343/384
Wavelength (λ) = 0.893 m
The two questions can be solved with the use of formula
Answer:
The answer is option A.
You speed up 8 m/s every second
