Will an object with a density of 1.05 g/ml float or sink in water? explain

The object will sink, because it is more dense than water.

Let's see this in detail. There are two forces acting on the object:

- its weight, which points downward, given by

where is the object's density, is its volume, and g is the gravitational acceleration.

- The buoyancy force, which points upward, given by

where is the water density, is the volume of water displaced by the object.

We see that it is always , so the object will sink. In fact:

. We are told the object's density is 1.05 g/mL, while the water density is 1.00 g/mL.

: the two volumes are equal when the object is completely submersed, and the volume of water displaced cannot be greater than the volume of the object.

So, W > B, and the object will sink.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
