A current in a river flows downstream at a speed of 2 m/s. A swimmer can swin with a speed of 0.5 m/s with respect to the water. The swimmer heads directly across the stream, and crosses the stream in a time of 30 seconds. How wide is the stream?

im not to sure what it is

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

their crystal patterns have been disrupted by stress

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!
