7. A box with a mass of 3.2 kg is pushed 0.667 m across a floor with an acceleration of 3.2 m/s². How much work is done on the box?

W= 6.83 J

Explanation:

According to the definition of work

W= F S

and

F= ma

then

W= m x a x S

W = 3.2 x 3.2 x 0.667

W= 6.83 J

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!
