astronomer's send probes to planet's to take pictures of their surfaces. an astronomer thinks that briny water flows on Mars because he noticed certain features in one picture of Mars. which method did the astronomer use to form this hypothesis?

i don't know that i agree with that but what's the question ?

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!

the right answer is 0.3 meters per second
