Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
Do batteries have resistance?
Yes they do have a resistance. Even though a battery is a voltage source it has some thevenin resistance. Every lead plate and cell of sulfuric acid, will have a small resistance. The thevenin resistance is equivalent or sum of all those resistances.
Does the alternating current supplied to the armature winding of a DC motor gets converted to dc by a commutator before it flows through the armature coil of the DC motor?
The commutator is a rotating switch, which reverse the polarity of the generated voltage every half-cycle. So it acts to rectify the output voltage.
What is the use of resistance in a LC circuit?
every inductor has some resistance. In circuit diagram, ideal inductor is shown in series with a resistor(value being equal to coil's resistance) to make analysis easy.
What part of motor makes the current in the coil reverse every half turn so that motor spins continuously?
The direction of the current flowing through it must be changed after every half rotation. Otherwise, when the north pole of the coil comes near the south pole of the magnet, there will be attraction between them and the coil will stop rotating.
In DC motor is the armature plus brushes resistance substantially the same for every rotational position of the armature?
yes
Why does a armature motor spin continuously?
It does because it changes every half turn.
Does every shape have rotational symmetry of order 1?
Yes but it's not normally included
What is the suns rotational period?
25 days
Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
What is the earths rotational period?
The earth rotates 360 degrees every 23 hours, 56 minutes and 4.100352 seconds.

Was there any resistance to Nazis and their treatment of the Jews?
Yes, there was resistance at every level, However what people could actually do was limited.
Who was the last person eaten by cannibal?
This happens some where every single year. So to say "The Last" would be substantially incorrect.
What is the rotational period of the Celestial Sphere in hours and how would you determine that?
The rotational period of the celestial sphere is simply the reflection of Earth's rotation; therefore, it rotates once every 23 hours and 56 minutes. You can determine that by observing the apparent movement of distant stars.
What is the number of degrees a figure rotates called?
It is called its order of rotational symmetry depending on its shape as for example a square has rotational symmetry to the order of 4 because it returns to its same shape every time of a turn of 90 degrees and so 360/90 = 4
