The , is a dimensionless group important in heat transfer calculations. it is defined as , where is the heat capacity of a fluid, is the fluid viscosity, and is the thermal conductivity. for a particular fluid, 0 583 j/(g c), 0 286 w/(m c), and 1936 lb /(ft h). estimate the value of without using a calculator (remember, it is dimensionless), showing your calculations; then determine it with a calculator.

as we gain mass the force of gravity on us increases.

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.
