Answer:
yes
Explanation:
1.98×10 m/s
you can use a physics text
I remember but am not sure
3.00 × 10 m/s
I think you do 10 ×10 in 8 places for both them you do the rest
No...and even if it did the present that you are in would not be the same...theres no need for time machine because whatever happens , happens for good because its from GOD.
ANSWER
625 m/s
EXPLANATION
Given:
• The frequency of the sound wave, f = 250 Hz
,
• The wavelength, λ = 2.5 m
Find:
• The speed of the wave, v
The speed of a wave of wavelength λ and frequency f is given by,
Substitute the known values and solve,
Hence, the speed of the wave is 625 m/s.
Answer:
g ≈ 7.4 m/s²
Explanation:
The acceleration due to gravity on planet XX is ...
g = GM/r² = (6.67·10^-11 × 4·10^22)/(6·10^5)^2
g ≈ 7.4 m/s²
