If 2.0j of work is done in raising 180g apple, how far was it lifted?

An apple is lifted "1.1337 meters" far.

Given values are:

Work done,

Mass,

or,

            = 0.18 kg

and,

As we know the formula,

→

or,

→                      

By substituting the values, we get

→                          

→                          

→                          

Thus the above response is correct.

Work = (force)x(distance)

Since we're lifting, the 'force' is the weight of the apple.

Weight = (mass)x(gravity)

Weight = (0.180 kg)x(9.8 m/s^2)

Weight = 1.764 Newtons

2.0 J = (1.764 N) x (distance)

Distance = 2.0J / 1.764N

Distance = 1.13 meters

d) physical means can be used to separate the components of air.
