What do falling prices signal in a market economy? 1 consumers want an increase in what is being produced. 2 producers have an incentive to provide more goods. 3 consumers have an incentive to purchase more goods. 4 producers want to decrease what they are supplying.

The correct answer is 3: "Consumers have an incentive to purchase more goods".

The demand curve represents the quantity of a certain good or service that consumers are willing to purchase in the market at different price levels. The law of demand states that there is an inverse relationship between price and quantity demanded (ceteris paribus, hence, given that the rest remains equal).Therefore, when the price charged decreases, the amount that consumers are willing to buy of that product increases. Incentives are obvious, the demand of the product increases because consumers can use it to satisfy their needs at a cheaper price.

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
