Answer:
0.05 meters
Explanation:
Given that:
Frequency of wave = 6 x 109Hz
Assume the wave travels at the speed of light, V = 3 * 10^8 m/s
The wavelength is related to frequency and speed of wave using the relation ;
v = fλ
λ = speed of wave, V / frequency, f
λ = (3 * 10^8) / (6 * 10^9)
λ = 0.5 * 10^(8 - 9)
λ = 0.5 * 10^-1
λ = 0.05 m = 5cm
Answer:
Abolished the old immigration quotas.
Explanation:
Since the Immigration Act of 1924, immigration was based on a national-origins quota system, which provided immigration visas to 2% of the total number of people of each nationality in the United States, based on the 1890 national census.
The Immigration Act of 1965 abolished those immigration quotas and established a visa system for reuniting immigrant families and attracting skilled labor people to the United States.
Answer:
C. 6,8,10
Explanation:
<u>Pythagorean triples</u> are sets of three sides of a triangle (leg, leg, hypotenuse) that are natural numbers, like 3, 4, and 5.
3^2 + 4^2 = 5^2, so it's a triple.
6,8,10 is a triple because it can be simplified to 3,4,5 by dividing each term by 2; it's similar to the 3,4,5, so it's a triple.
Before the bombing of Pearl Harbor by the Japanese, most Americans were hesitant to engage in another European war (the first one being WWI). American sentiment began to change, however, after the Germans began sinking American ships.
