A5.0-kg object is pulled along a horizontal surface at a constant speed by a 15-n force acting 20° above the horizontal. how much work is done by this force as the object moves 6.0 m?

84.6 J

Explanation:

The work done by the force is given by

where

W is the work done

F = 15 N is the force applied

d = 6.0 m is the displacement

is the angle between the force's direction and the displacement

Substituting the numbers into the equation, we find

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!
