Why does temperature decrease with higher altitude? a. air is held strongly together by gravity, so there is less heat transfer. b. air density is lower, so there is less heat transfer. c. air density is higher, so there is less heat transfer. d. air pressure is higher, so there is less heat transfer.

Write the quartstogallons java class that declares a named constant to hold the number of quarts in a gallon (4). also declare a variable to represent the number of quarts needed for a painting job, and assign an appropriate value—for example, 18. compute and display the number of gallons and quarts needed for the job. display explanatory text with the values, for example:

We as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). in a computer’s language, however, it is preferred to have the operators on the right side of the operands, i.e. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix.write a program that takes an “infix” expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % (example infix expression: (7 - 3) / (2 + 2)postfix expression: 7 3 - 2 2 + /result: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';
