The answer is 1,250 W.  
Solution: 
To use the power rule P = VI, we need to know both the current I flowing through the resistor, and the voltage V across the resistor. But by substituting Ohm’s law I = V/R, we can also express the power rule equation P = VI as 
     P = R (V/R)^2 = R V^2 / R^2 = V^2 / R 
We can now substitute the values for the resistance and voltage into the equation to get the power rating: 
     P=V^2 / R = (120)^2 / 11.5 = 1252.17 Watts ≈ 1250 Watts

Which part of the electromagnetic spectrum is divided into seven ranges of wavelengths and is the part visible to the human eye
oksano4ka [1.4K]
In one of the most amazing coincidences in all of science,
the part of the electromagnetic spectrum that's visible to the
human eye is called "visible light".

Visible light is not 'divided' into anything. We mention the names
to seven of the colors in visible light. But all of the thousands of
OTHER colors that we can see are in there too, even though we
don't bother to list their names when we buzz through the rainbow
in the third grade.

A race car circles 10 times around a circular 8.0-km track in 20 min.
Otrada [13]
Find the average speed and the average velocity.

Average speed = distance / time

distance = 10 x 8000 m = 80,000 m
time = 20 min * 60 s/min = 1200 s

Average speed = 80,000 m / 1200 s = 66.67 m/s

Average velocity = displacement / time

Given that the race car made complete circles the final poin is the same initial point, then its displacement is zero and the average velocity is zero too.
