A scientific inquiry is a form of studies that scientist use to help form an answer. A scientific inquiry involves asking questions, making hypotheses, making observations, analyzing, and testing the object.
Answer:
Iron
Explanation:
The buoyant force equals to the weight of water being displaced by the object.
Since, the volume of both iron and wood is equal and the wood is not completely submerged, but the iron block is completely submerged i.e more volume of the water is being displaced by the iron block.
Hence, the buoyant force is more on the iron.
Answer:
Solubility
Explanation:
Material becomes soluble in solvent and disappears.
Answer:
3091.56
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s² (positive downward and negative upward)

Distance traveled in the first stage is 1093.75 m

Velocity at the end of first stage is 87.5 m/s

Acceleration of the second stage is 4.5 m/s²

Distance traveled in the second stage is 1100 m

Distance traveled after the second stage has stopped firing is 894.81 m
Total height the rocket reached = 1093.75+1100+897.81 = 3091.56 m
