If a boy rides his bicycle 100 meters in 20 seconds to the end of the street how fast did he ride his bike

Equation: 
v _{av} = average velocity
d = displacement
t = time

100/20 = 5m/s

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
