A spacecraft descends vertically near the surface of Planet X. An upward thrust of 32.0 kN from its engines slows it down at a rate of 1.20 m/s², but if an upward thrust of only 11.4 kN is applied, it speeds up at a rate of 0.80 m/s².
Apply Newton's second law to each case, slowing down or speeding up, and use this to find the spacecraft's weight near the surface of Planet.

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!
