Which of the following will not cause the production possibility frontier to shift from ppf 1 to ppf 2? A. the discovery of previously unknown oil fields B. a decrease in the unemployment rate C. an increase in the stock of capital D. an improvement in technology

B. a decrease in the unemployment rate

Explanation:

The production possible frontier shows the maximum output of two goods that can be produced using fixed input.

A decrease in unemployment will not result in a shift in the ppf from point 1 to 2, however, am increase in technology will increase productivity in both enterprise causing a shift in the ppf from 1 to 2. The discovery of previously unknown oilfield will also result in an upward shift of the ppf because since both enterprise depend on similar input, there will be more raw material for production hence an upward shift in the ppf.

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
