50
Explanation:
The mechanical advantage of a machine is given by

where
is the output force
is the input force
For the crowbar in this problem,
is the force in input applied by the worker
is the force that the machine must apply in output to overcome the resistance of the window and to open it
Substituting into the equation, we find

A continuous spectrum contains all the wavelengths
A discontinuous spectrum has strips of specific colors and can be used to identify the elements making it.
