Beginning in 1873, a series of Supreme Court decisions limited the scope of Reconstruction-era laws and federal support for the so-called Reconstruction Amendments, particularly the 14th and 15th, which gave African Americans the status of citizenship and the protection of the Constitution, including the all-important right to vote. Bill, passed by Radical Republicans in Congress in 1867, that treated Southern states as divided territories. Sometimes called the Military Reconstruction Act or the Reconstruction Act, the First Reconstruction Act divided the South into five districts, each governed by martial law. It was the first of a series of harsher bills that the Radicals passed that year.
It can be seen in their policies, he believed you must have a strong military to strive.
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
1. malaria 2. rivers had terrible waterfalls..too dangerous...until the steam engine was invented it was incredibly dangerous 3. deserts....they didn't know how to travel through the deserts and find an oasis which made it very difficult to travel through
