The wavelength of yellow light in a spectrum is about 0.00002 inches. Which number best approximates this length as a power of 10?
A. 2 x 10-5
B. 2 x 10^5
C. 2 x 10-4
D. -2 x 10^5

since the 2 is the 5th digit after the decimal, scientific notation will be 2*10^-5 thus choosing

Thus choice A is the correct answer.

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
