Answer:
Technician A is correct while Technician B is incorrect.
Explanation:
If Technician a says that that both slip rings must be insulated from the rotor shaft, then, technician a is correct.
If technician b says that at least one slip ring must be grounded to the shaft to provide a complete circuit for current flow, this statement is incorrect because each slip ring must be connected to one of the three phases of rotor windings. And the slip ring brushes are connected to a resistive device ( like a rheostat). When the slip rings turn with the rotor, the brushes will maintain constant contact with the rings and transfer the resistance to the rotor windings. Therefore, Technician A is correct while Technician B is incorrect.
Its because of the static electricity.As we rub, the positive and negative charges are acquired by the plastic rod and duster.
If we bring paper bits near them, the charges possessed by the paper bits get attracted towards the charges in plastic rod.

Explanation:
As we know that the deepest point of the canyon is 800 m
so here we will have the displacement of the rock in the canyon is same as that of depth of the canyon
So here we will say
now we have
That's true. The give-away is "observation ... in the real world". That's what "field reports" are.
The part I'm not so sure about is those "entific findings".
