Answer:
(c) no different than on a low-pressure day.
Explanation:
The force acting on the ship when it floats in water is the buoyant force. According to the Archimedes' principle: The magnitude of buoyant force acting on the body of the object is equal to the volume displaced by the object.
Thus, Buoyant forces are a volume phenomenon and is determined by the volume of the fluid displaced.
<u>Whether it is a high pressure day or a low pressure day, the level of the floating ship is unaffected because the increased or decreased pressure at the all the points of the water and the ship and there will be no change in the volume of the water displaced by the ship.</u>
Hey there!
Alright, it looks like you've got the second question on the top right, but I can't figure out the answer you've got for the first.
Using Newton's Second Law Of Motion, we have:
F = ma
We plug in our values:
F = 5(1)
That would give us 5 Newtons of force.
For the last one:
Even if two balls are given the same acceleration, the determining factor is <em>weight.</em> If a ball is lighter, it needs less acceleration to go faster. If it's larger, it needs more to make it go at that same speed. That's why that 5 newtons makes sense because it's 5 kilograms as opposed to 0.6 kilograms. It's heavier, and needs more force.
Hope this helped!

Hello. This question is incomplete. The full question is:
Two blocks are stacked on top of each other on the floor of an elevator. For each of the following situations, select the correct relationship between the magnitudes of the two forces given.
The elevator is moving downward at a constant speed.
The magnitude of the force of the bottom block on the top block is _____ the magnitude of the force of the earth on the top block.
Answer:
The magnitude of the force of the bottom block on top block is equal to the magnitude of the force of the top block on bottom block.
Explanation:
As the elevator is descending, there is only a normal force being applied to the lower surface of the block. This force has a magnitude equal to the force of the upper block, because the only acceleration that is acting in this case is the force of gravity. From that force, the resulting force is zero.
