What is the force and distance relationship for a fixed pulley?

Force is a vector quantity which when applied to an object can cause change in its velocity. When Force is applied to an object, the object if stationary moves to a certain distance depending upon the amount of force applied.

A pulley is a wheel with a groove that holds a rope, cable or belt, and is used to help lift an object.

The relationship of Force and Distance is the same for a fixed pulley as well. Except for one thing:

Normally the distance covered by an object is in the direction of the Force.

Using a pulley, an object can be moved with that same Force in a different direction. Using a pulley, a person can apply force in a direction suitable for him while moving the object.

                               Force = mass of an object * Distance Covered

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
