In physical science, pressure quantifies the amount of force that is applied at a certain area. Mathematically, this can be transformed as,
Pressure = Force / Area
It is also to be noted that force is the product of mass and acceleration due to gravity.
Force = mass x acceleration due to gravity
Substituting,
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, substitute this to the first equation,
Pressure = 3430 N / 1m²
<em>ANSWER: Pressure = 3430 N/m² = 3430 Pa</em>
Answer:
Poor planning, and disease
Explanation:
The obstacles that the French faced while attempting to build a canal across Panama were diseases and poor planning. The French dealt with constant outbreaks of malaria and yellow fever, which slowed construction and caused the deaths of thousands of workers. The French also did not take into consideration the geographical differences between the Suez Canal region and the Panama region. The French had succeeded in building a canal at sea level in Egypt, and they mistakenly thought a similar design would work in Panama. However, the difference in the Atlantic and Pacific Ocean sea levels, as well as the difference in elevation of the Panamanian terrain, prevented them from building a sea-level canal. The United States knew about these two problems when they undertook the project. They took preventative measures by reducing the disease-spreading mosquito population and using a canal-lock system to overcome the elevation obstacle in Panama.
Answer:
About 30% of the solar energy that reaches Earth is reflected back into space. The rest is absorbed into Earth's atmosphere. The radiation warms the Earth's surface, and the surface radiates some of the energy back out in the form of infrared waves.
Explanation:
Answer:
This consists of pebbly beds associated with ancient blown sands, sometimes of considerable thickness. Above this series of deposits comes the Head or Rubble Drift, formed during a greater elevation of the land.
Eastern Europe. Communism was forced into Eastern Europe during WW2. Because of this, people state that being in a communist environment brought down the economy. Hope this helped!
