Couldn’t really read or see the problem clearly, but from what I think I saw I would say B
A frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely locate and orient the coordinate system and standardize measurements.
It is a physical concept related to an observer and the observer's state of motion.
In n dimensions, n+1 reference points are sufficient to fully define a reference frame.
Answer with Explanation:
We are given that
Current,I=12 A
V=11.5 V
I'=9 A
Internal resistance,r=0.05 ohm
a.We have to find the emf of battery.
Using the formula
b.Voltage of ligh
Hence, the current through the starting motor when the light areon=61 A
