If you push twice as hard against a stationary brick wall, the amount of work you do

It remains zero

Explanation:

The work done on an object is given by:

where

F is the magnitude of the force applied

d is the displacement of the object

is the angle between the direction of the force and of the displacement

In this problem, the object is the wall, which is stationary. Therefore, the displacement of the wall is zero:

d = 0

And so, the work done is always zero, even if the force applied is twice as stronger.

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!
