Explain the difference between these two statements: result = 9*2 result = 9*2;

The following assignment statements either contain at least one error, or could be improved in some way. Assume that radius is a variable that has been initialized. First, identify the problem, and then fix and/or improve them: 33 = number my variable = 11.11; area = 3.14 * radius ^2; x = 2 * 3.14 * radius;

What is the difference between 5 and 5?

Explain why the following expression results in 0 for false: 5 > 4 > 1

A vector can be represented by its rectangular coordinates x and y or by its polar coordinates r and . Theta is measured in radians. The relationship between them is given by the equations: x=r*cos() y =r*sin()

The speed of a sound wave is affected by the temperature of the air. The formula for

The Speed in term of the degrees Celsius Is speed=55^2+0.6*C

Create a variable cdegree

(and give it an initial value degrees Celsius Which you like).

Convert this to the speed of a sound wave and store to the result in a variable soundwavespeed
