Answer:
the water level remains same
Explanation:
This can be explained by Archimedes's principle which says that the wood will sink if weight of wood is more than the weight of the water displaced with weight equal to the water displaced otherwise the wood will float.
Therefore, buoyancy or the buoyant force is the same as the weight of wood, the weight of the water displaced by wood is also the same as that of the weight of wood.
Thus, we can see that the weight of the wood remains same and so is the level of water.
A conservative force is a force that when work is done against this force the work done does not depend on the path taken only the initial and final position.
Answer: false
Explanation: the longer the period, the less thef= frequency
momentum= mass × velocity
p= 50×18
momentum= 900 kg m/s
