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
The United States wanted a method of export and transportation to and from the United States originally when Panama was a part of Colombia. This is why they helped Panama's revolution to become its own independent country. If they had good relations and Panama went as planned, the US could finally build the canal they wanted so badly. The canal now allows transportation of many of the goods we purchase and use today here in the United States.
Answer:
they are most employed in manufacturing
Explanation:
In 1820 120 thousand Native Americans lived east of the Mississippi River, by 1844 fewer than 30 thousand were left there.
As the US pushed the boundaries of its territory East and West the Native Americans suffered. President Andrew Jackson passed the Removal Act on the Congress in 1830, the bill forced Native Americans to leave the US and settle in “Indian Territory” west of the Mississippi River. Americans needed more land for white settlement, army and militia patrols supervised the tribes.
The Cherokee tribes did not agree with the bill and challenged it, thousands of federal soldiers entered the territory and forced them to relocate. It was on this moment that the “Trail of Tears” happened, Cherokees were forced to march a thousand miles into Indian Territory and about 4 thousand of them died. The Indians were not provided with adequate supplies and many died due to disease and starvation. Some estimate that close to 100 thousand Native Americans lost their lives and their homelands in the series of forced migrations that lasted through the 1840s.
