Materials used to build the central pacific railroad were shipped

Materials used to build the central pacific railroad were shipped around South America

Explanation:

Before the continental railroads, the travel through stagecoach was costly, and it took a long period to travel. However, there were available options for going through the sea using the South American path, but the distance that was covered was also long.

This was the reason that the South Americans opted to provide materials for construction of railroads to safe people from traveling for long periods and in long distances. And also ensure products that were shipped reached their designated destination earlier enough.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
