If there is a huge boulder on your lawn and you want to determine its density, but it is too large to move, how could you calculate its density?

Density = mass/volume

Calculating the volume by measuring the area it occupies and length.

Also, the heavier an object the higher density it has since density is directly proportional to mass.

This means the stone will sink when placed in water and it must have density higher than that of water since it's much heavier.

By approximation it must have more than 1000kg per m³. The mass can be obtained this way.

The best way to find density of irregular objects is to put them in water.

This is what I think.

All the best!

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.

statement #3 on andre"s list is false.
