Two point charges of magnitude 4. 0 μc and -4. 0 μc are situated along the x-axis at x1 = 2. 0 m and x2 = -2. 0 m, respectively. What is the electric potential at the origin of the xy-coordinate system?.

i think its a and d

step-by-step explanation:

the answer is ! ?

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
