The price elasticity of demand for urban transit fares has been estimated to lie between -0.1 and -0.6. Based on these results, what is the economic argument for raising transit fares? What political arguments might local governments and transit authorities encounter in opposition to these economic arguments?
The Surf-excel company uses a machine to fill boxes with soap powder. Assume that the net weight of the boxes of soap is normally distributed with mean 15 ounces and standard deviation 0.8 ounces. 25% of the boxes will be heavier than a certain net weight w and 75% of the boxes will be lighter than this net weight. Find w
The electric field has a magnitude of 3.0 N/C at a distance of 30 cm from a point charge. What is the charge?
Ram is given a positive integer N. He wishes to convert this integer into a single numeral . He does so by repeatedly adding the numerals of the number until there is only a single numeral . Help Ram by providing the single - numeral number finally obtained .
Input
The input is a single line containing a positive integer N.
Output
The output should be a single line containing a single-numeral number.
Explanation
In the example, the given number is 545.
As the number is more than a single numeral, repeatedly add the numerals like
5 + 4 + 5 => 14
1 + 4 => 5
So, the output should be 5.
Sample Input 1
545
Sample output 1
5
Sample Input 2
111
Sample output 2
3
Calculate the change in energy for the following processes. Determine if the process is endothermic or exothermic.
1. A gas releases 35 J of heat as 84 J of w was done to compress it.
2. A gas absorbs 48 J of heat as it does 72 J of work by expanding.
