Orbital speed = orbital path distance/time period = 2*pi*r/T
T=27.3days*24*3600=2358720s
2*pi*3.8*10^8m/2358720s = 1020m/s
Hope this helps! Please rate if my answer helped you! Any questions please feel free to ask! Thank you so much!!
Since our earlobes repeatedly bounce from our inner ear twords the eardrums, this is compeltely true.
Answer:
The added mass will mean a longer period of oscillation.
Explanation:
The period of oscillation here is given by the formula;
T = 2π√(m/k)
Where m is mass and k is spring constant
From the equation of oscillation period above, it's obvious that when we increase the mass, the oscillation period will also increase.
Thus, the added mass will mean a longer period of oscillation.
Answer:
9 m/s
Explanation:
Wyatt maintains the maximum speed for the rest of the race. This motion begins when his displacement is 40 m and the time is 7 s. At time 12 s, his displacement is 85 m. Because this motion is constant-velocity, the maximum speed is given by
Statements A, B, and C are true.
