According to the textbook, desirable objects are perceived as closer than neutral objects. In an experiment examining this phenomenon, the perceived distance of the objects is a(n) variable in this study.

independent

Explanation:

An independent variable remains under the control of the experimenter. The variable can be altered according to the desire of the experimenter. Thus the changes that occurred in the independent variable causes the changes in the dependent variable or experimental variable. The experimental variable is the outcome for the purpose of study.

The distance of the object is the independent variable, as this can be changed and will affect the fact that how the object is perceived which is the dependent or the experimental variable.

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
