My best guess would be sun because it is bright but is surrounded by shadows on all sides.
Explanation:
Given that,
Mass = 0.254 kg
Spring constant [tex[\omega_{0}= 10.0\ N/m[/tex]
Force = 0.5 N
y = 0.628
We need to calculate the A and d
Using formula of A and d
.....(I)
....(II)
Put the value of
in equation (I) and (II)


From equation (II)


Put the value of
in equation (I) and (II)


From equation (II)


Put the value of
in equation (I) and (II)


From equation (II)


Put the value of
in equation (I) and (II)


From equation (II)


Hence, This is the required solution.
Velocity is d/t distance over time. Increase velocity (speed) decrease. Increase d velocity increases.
We know average speed =total distance/time taken
So avg speed=(85+63)/(5+5)=14.8km/hr
The answer is b i just did the test
