Answer:
14.9 m /s
Explanation:
n = n° x v /[ v -v (s) ]
n is apparent frequency , n° is source frequency,v is speed of sound and v(s)
speed of source.
2300 = 2200 x 343 / [343 -v(s)]
v (s ) = 14.9 m /s.
Answer:
Explanation:
c is your answer C) A substance that result when another substance is separated into its component parts.
Answer: 2.67 k/s^2
Explanation:
Given that:
Initial velocity V1 = 1.0 k/s
Final velocity V2 = 1.8 k/s
Time taken T = 0.3 seconds
acceleration of the meteoroid = ?
Since acceleration is the rate of change of velocity per unit time
i.e acceleration = (V2 - V1) / T
Acc = (1.8 k/s - 1.0 k/s) / 0.3 seconds
Acc = (0.8 k/s / 0.3 seconds)
Acc = 2.67 k/s^2
Thus, the acceleration of the meteoroid is 2.67 k/s^2
Out of those choices, it would be Saturn.
Hope this helps!
