The rule used to translate the image is 
.
In this question we are going to speak of point translations. Vectorially speaking, a translation between two points is defined by this expression:
(1)
Where:
- Original point.
- Translation vector.
- Translated point.
If we know that 
and 
, then the translation vector is:
Therefore, the rule used to translate the image is .

A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms
B) Resistance at medium and larger speeds are;
At medium speed; R is less than that at low speed
At larger speed; R is less than that at medium speed.
A) We are given;
Voltage; V = 120 V
Current at lower speed; I = 0.25 A
Formula for resistance here is;
R = V/I
R = 120/0.25
R = 480 ohms
B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.
Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.
