A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. The final speed after mass 1 falls 4.5m is approximately 6.6 meter per square second.

How much gain in speed each second does a freely falling object acquire?

That depends on many different factors, the two most obvious ones being friction and gravity. If the object is completely frictionless, and falling at 9.8m/s2 (an approximation of the average acceleration from Earth's gravity), then it would gain 9.8m/s in speed with each second that passes. If on the other hand it was falling in a frictionless environment on Jupiter, it would gain approximately 24.79 m/s.

A cord passes over a weightless and frictionless pulley masses of 200 and 300 gramd are attached to the ends of the cord find the distence the masses will move during the fifth second after they had?

To find the distance the masses will move during the fifth second, you need to first calculate the acceleration of the system using Newton's second law. Then, using this acceleration and the equation of motion, you can find the distance traveled by the masses in the fifth second. Make sure to consider the initial conditions of the system.

How do relay contacts become pressed together when a current passes in the coil?

Relay contacts change state (become pressed together) when a current passes through the coil because that current causes a magnetic field to be induced which attracts the armature, to which is attached the contacts.
