Complete question is:

Tech A says that when testing a relay winding with an ohmmeter,  it should show the winding is open. Tech B says that the solenoid closes a set of heavy contacts that send current flow to the starter motor. Who is correct?

Tech B is correct

Explanation:

First we need to know the basic working principle or relays. It is basically an electromagnetic switch controlled by a coil. When voltage is applied to the coil, the generated current produces an electromagnetic pulling the internal contacts and activating the switch.

Now, lets review each statement:  

This is False. The winding is made of a conductive filament, like copper, so testing with an ohmmeter will show a closed circuit, usually with a low resistance value.

This is True. As the explanation above, the solenoid produces an electromagnetic field that activates the contacts, switching on or off the desired circuit.

the force required to move the cart is divided by three or 33.33 n.

this is a good question! i'll do some research and come back when i have the answer!
