What is the angle of rotation counterclockwise about the spinner's center that maps label g to label b?
108
144
180
216

The answer is:

The angle of rotation counterclockwise about the spinner's center that maps label g to label B is 180° .

Step-by-step explanation:

The angle of rotation counterclockwise about the spinner's center that maps label g to label B is 180° .

Look at the attached picture of a spinner:

We know that the angle formed by a straight line is  equal to 180°

So, in order to map label g to label B we have to set the needle of the spinner straight. Hence the angle formed by the needle is 180°

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:
