<span>The sprinter is advised to reduce his speed slowly after
completing the race because of the power that is needed when the stoppage is
down in a faster manner could be very great. This would translate to the great
usage in gasoline. Also, the inertia of the vehicle is quiet high so it is hard
to stop it very suddenly. </span>

Answer:
Unbalanced forces is the correct answer.
Explanation:
Answer:
a) 0.568 kg
b) 474 kg/m³
Explanation:
Given:
Inner radius = 8.82 cm = 0.0882 m
Outer radius = 9.91 cm = 0.0991 m
Density of the liquid = 948.00 Kg/m³
a) The volume of the sphere =
or
volume of sphere = 0.0012 m³
also, volume of half sphere =
or
volume of half sphere =
or
Volume of half sphere =0.0006 m³
Now, from the Archimedes principle
Mass of the sphere = Weight of the volume of object submerged
or
Mass of the sphere = 0.0006× 948.00 = 0.568 kg
b) Now, density =
or
Density =
or
Density = 474 kg/m³
False the North Star never changes it position
