Answer:
3727.24km/h
Explanation:
Hello!
To solve this problem we must first know what is the distance from the earth to the moon, this will be our radius.
=384400Km
Then we find the distance traveled which would be the perimeter of a circle = 2πr, finally to find the speed we divide the distance traveled by 27 days.
Finally we use conversion factor to have the speed in km / h
solving

the moon is orbiting at speed of 3727.24km/h
The correct answer is good architecture is
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:
Final velocity v = 4 m/s
Explanation:
Given:
Initial velocity u = 0 m/s
Acceleration a = 0.16 m/s²
Distance s = 50 m
Find:
Final velocity v
Computation:
Using; v² = u² + 2as
v² = (0)² + 2(0.16)(50)
v² = 16 m/s
v = 4 m/s
Final velocity v = 4 m/s
