Answer:

-125 degree celcuis

Explanation:

Using the formula;

θ - 0/100 - 0 = 45 - 30/18 - 30

Let us recall that the right hand side refers to the temperature in degrees centigrade while the right hand side stands for the temperatures in the scale of the thermometer. In both cases, the denominator is the fundamental interval.

So, we have;

θ/100 = 15/(-12)

-12θ = 1500

θ = 1500/(-12)

θ = -125 degree celcuis

with the same generator, so the only factor for producing the slectric field is only the speed. The faster the rotational speed of the generator the greater it produce electric field. So the sequence is 3000 rpm < 3200 rpm < 3400 rpm < 3600 rpm
