Homework Chapter 5 - Essay Example Explain how air pressure tendency can be a useful indicator of future weather. Answer: Air pressure tendency can be a useful indicator of weather forecast as it is the change in air pressure over a specific time interval, such as several hours. Falling or rising of air pressure signals the approach of stormy or fair weather respectively. Aneroid barometers are usually equipped with second pointer that serves as reference marker for setting current reading. The user can observe the new pressure reading taken at a later time and compare it with reading earlier set on second pointer to determine air pressure tendency. The barograph then provides a continuous trace of air pressure variations with time, making it easier to determine air pressure tendency and forecasting weather. Question 5. Air is a compressible mixture of gases. How does this property of air affect the rate at which air pressure decreases with increasing altitude? Answer: Air is a compressible mixture of gases, so its vo lume and density are variable. The pull of gravity compresses the atmosphere so that the maximum air density is at the earth’s surface. So, the atmosphere’s gas molecules are closely spaced at the earth’s surface and the spacing between molecules increases with increasing altitude. Thus, the number of gas molecules per unit volume (air density) decreases with increasing altitude. Question 6.

Mobile applications in business have a number of limitations. Firstly, these applications are small in size to be able operate within small memory and storage space available in the phone, and hence cannot handle large volumes of data. Secondly, mobile phones use Wi-Fi protocol to transmit data. Thus, most of the applications are susceptible to viruses. Lastly, some mobile phone applications for businesses are constantly evolving and very complicated to use, and therefore ordinary business may have find problematic to employ in their businesses. Microsoft Access, also called Ms Access, is database management application under the Microsoft office suit. It is a useful information management application that primarily stores data, allows analysis of the stored data and has mechanism for reporting information of the stored data. It is handier in managing large amounts of data that would otherwise be inefficient to handle with spreadsheets. In addition, MS acess allows an individual to store multiple related data together, create relations, allows automation of repeated processes through Macros, and eliminates unnecessary duplication of data which would otherwise jeopardize the accuracy of any analyzed data. Ms Access has inadequacies despite its ability to provide database solutions for small and medium business entities. It can only support databases, records and fields, of up to 2 GB and a maximum of 255 simultaneous database connections. For it to support larger quantities of data i.e. greater that 2GB and connections exceeding 255, the tables and applications should be
