The wavelength of violet light in a spectrum is about 0.4 meters. which number best approximates this length as a power of 10
a. 4 x 10^-7
b. 4 x 10^-6
c. -4 x 10^7
d. 4 x 10^7

Option A is correct.

Step-by-step explanation:

The wavelength of violet light in a spectrum is about 0.0000004 meters.

Now, we have to express this wavelength best approximate as a power of 10.

Now, 0.0000004 can be written as

Therefore, 0.0000004 meters = meters

So, 0.0000004 meters = meters

Hence, option A gives the correct answer. ( Answer )

answer: h

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
