The biggest obstacle faced in building the Transcontinental Railroad was having to pass over the Sierra Nevada Mountains in California.
they faced many land obstacles, very little pay, and long hours.
The threat of the Native Americans.The Native Americans felt upset about being pushed out of their own land. They didn't believe in land ownership. So when people came looking for places to set their tracks, the Native Americans came and scalped them, burned them, or killed them.
The Sierra Nevada of California
Harriet Tubman's biggest obstacle was discovering the Underground Railroad. She became famous by finding the Underground Railroad, that led to the north. She freed over 300 slaves.
The Sierra Nevada mountains.
the main obstacle was the out break of yellow fever on the workers
* Some of the obstcales in building the Canal were mosquitoes * The mosqutioes caused maliria and yellow Fever * Another obstacle was mud slides * Another obstacle was explosions *
A railroad would make it possible to travel the distance to the Pacific much faster and much more easily.
war and the disagreements of citizens vs, power
The mountains proved to be a formidable obstacle in the building of the railway, proving costly in delayed time and soaring construction costs.
I guess you mean skyscraper. The initial obstacle to building such a tall building would be the softness of the terrain, as most of Mexico City downtown lies on the desiccated remains of Lake Texcoco. Nowadays, most tall buildings (+20 stories and more) are built on the periphery of the city, on financial districts such as eastern Reforma Avenue, Santa Fe and Colonia Del Valle.
The first obstacle was political, as the logical route would utilize Chicago and the American Midwest. The next obstacle was the terrain of the Canadian Rockies; rugged and barren over the Canadian Shield portion and mushy in the muskeg region of Northern Ontario. It took four years to complete.
obstacle of reading
I personal think that 1 of Harriet Tubman's most important overcoming obstacle was when she had escaped slavery alone with no one there with her. Another important overcoming obstacle was when she got out of slavery and into the South were there was no slavery and didn't have no one to welcome her to the land of freedom. Her exact words to this topic was: "I had crossed the line. I was free, but there was no one to welcome me to the land of freedom. I was a stranger in a strange land."
her largest obstacle
that test was as difficult as n obstacle
Obstacle is correct.
Moses had a major obstacle and that he stammered.
The verb of obstacle is obstruct. As in "to obstruct something or someone".
When a body hits an obstacle the force with which it hits the obstacle depends upon---the velocity at the installation of collision bt not on initial velocity.
We've seen some extreme athletes doing this, like David Belle. The tag for the activity is urban obstacle coursing. Belle's position is that the urban landscape is, in and of itself, an obstacle course. So he treats it as such, and with extreme athleticism. Use the links below to look at a couple of short clips of Belle in action. (There are more in the Related area.) Wimpy people need not apply for this kind of gig.
In general waves can: Wrap around the obstacle. This happens when the wavelength is larger than obstacle size. Bounce back as an echo off the obstacle. This happens when the wavelength is shorter than the obstacle size. Be absorbed by the obstacle. This occurs when the natural frequency of the obstacle matches the frequency of the wave...so-called resonance. Pass through the obstacle. There are several ways this can happen. But visible light passing through a glass window is one example.
