How many top quark lifetimes have there been in the history of the universe (i. e., what is the age of the universe divided by the lifetime of a top quark)? note that these powers of 10 follow the same rules that any exponents would follow.
(the age of the universe is around 100,000,000,000,000,000s. a top quark has a lifetime of roughly 0.1s. writing numbers out with all these zeros is not very convenient. such quantities are usually written as powers of 10. the age of the universe can be written as 1017s and the lifetime of a top quark as 10−24s.
note that1017 means the number you would get by multiplying 10 times 10 times a total of 17 times. this number, as you can see above, would be a one followed by seventeen zeros. similarly, 10−24 is the result of multiplying 0.1 (or 1/10) times itself 24 times. as seen above, this is written as 23 zeros after the decimal point followed by a one.)

Explanation:

First of all, we need to write both the age of the universe and the lifetime of the top quark in scientific notation.

Age of the universe:

(1 followed by 17 zeroes)

Lifetime of the top quark:

(we moved the decimal point 24 places to the right)

Therefore, to answer the question, we have to calculate the ratio between the age of the universe and the lifetime of the top quark:

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.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
