What is the acceleration at 1 second? Answer in units of m/s^2. What is the velocity at 2 seconds? Answer in units of m/s.

What is the position at 2 seconds? Answer in units of m.

-- From 1 to 3 seconds, the acceleration is 2.5 m/s².  (It changes suddenly at 3 seconds.)

-- At 2 seconds, the speed is 2.5 m/s .

-- At 2 seconds, the position is 1.25 meters.

BE CAREFUL !

I don't know where you got this graph, but you have to be very very careful when you try to read it.  The Y-axis is not at time=0.  It's at time=1.  And all the whole-number seconds are between the blue lines.

measure their densities same density, same sub

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!
