What does it mean when work is positive? velocity is greater than kinetic energy kentic energy is greater than velocity the environment did work on an object an object did work on the environment

Option (c) is the correct answer.

Explanation:

It is known that work is equal to negative of pressure times delta V.

Mathematically,      W = -

                                    = -

where                  P = pressure

  = change in volume

So, when work is positive then it means is negative.

                           W = -

                               = -

                               = +ve

Thus, we can conclude that when work is positive then work is done on the system or object by the environment.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
