two crates are submerged underwater. the crates are identical in size, but crate a is filled with iron and crate b has only air inside. which crate has a greater buoyant force acting on it?


1. crate b has a greater buoyant force acting on it because it is filled with air, so it will float. the object that floats will always have a greater buoyant force acting on it.

2. there is no way of knowing which object has a greater buoyant force acting on it until we can determine if they float. if both objects float, they have the same amount of buoyant force acting on them.

3. crate a has a greater buoyant force acting on it because it is filled with iron, making it heavier. buoyant force depends on the weight of the object.

4. both crates have the same amount of buoyant force acting on them because they are the same size and displace the same amount of water.

Explanation:

If an object displaces more more water than it has a higher buoyancy force. A sinking object is capable of displacing more fluids.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
