answer below:
Explanation:
Before the Industrial Revolution, transportation relied on animals (like horses pulling a cart) and boats. Travel was slow and difficult. It could take months to travel across the United States in the early 1800s before industrial revolution
The Industrial Revolution completely changed the way people traveled and how goods were transported.
the problem of traveling upstream was solved during the industrial revolution by the steam engine. in order to make better use of water transportation, canals were build to connect rivers, lakes and oceans. the invention of the railroad and the steam powered locomotive opened up a whole new world in transportation. even with steamboats and railroads, people still needed a better wat to travel between rivers and train stations. a new process called the "macadam " process was used to create smooth gravel roads
I hope this helps a bit.
Accumulators
Explanation:
An accumulator is a storage chamber in which a hydraulic fluid is stored under high pressure. Accumulators are the most common examples of energy storing device. It enables smooth movement, increases the efficiency of the hydraulic system and also stores energy during phases with lower demands.
External pressure is applied on the hydraulic fluid through mechanical devices such as an engine, piston movement, springs or through gasses compressed under high pressure. Hydro-pneumatic accumulators or compressed gas type are the most common type of accumulators found nowadays.
Answer:
c.attenuation
Explanation:
In telecommunication, it is called attenuation of a signal, be it acoustic, electrical or optical, to the loss of power suffered by it when passing through any transmission medium.
Attenuation is usually not expressed as a difference in powers but in logarithmic units such as decibels, which are more comfortable to use when calculating.
The attenuation is expressed in decibels (db) and the power is measured with this formula:
α = 10 * log (P1 / P2)
where P is the power both initial and final.
Answer:
-At 1000°C, liquid phase at 68 wt% Zn
-At 760°C, liquid+γ phase, liquid at 74 wt% and 66 wt% γ phase
-At 600°C, γ phase
-At 400°C, γ phase
Explanation:
The phase diagram will be used for the combination of the copper-zinc alloy, first 68% by weight of Zn will be located on the axis corresponding to the composition. Draw a vertical line upwards and go through the temperatures given by the exercise 1000, 760, 600 and 400 ° C. Later you have to know the phases for each of the temperatures. Draw a horizontal line within each phase and look at the adjacent phases and the composition of the alloy. For each of the temperatures, the phases are in response and the drawings are attached to the image.
