What distance does electromagnetic radiation travel in 0.45 ps ?

Explanation:

The distance traveled by electromagnetic radiation is given by:

where

v is the speed of the radiation

t is the time elapsed

Electromagnetic radiation travels at the speed of light, which is equal to:

The time elapsed in this problem is

Substituting into the equation, we find

which corresponds to

i think they are all correct

they seem good

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
