Click here to watch the If Then video The If Then Statement Many statements in math are of the if then form. In math notation such a statement is expressed as $P \implies Q$. Examples: 1. If n is even then $n + 1$ is odd. 2. If $\alpha$ is an angle in a right triangle then $\alpha \le 90^\circ$. 3. If $n = 6$ then n is even. 4. If it is raining then there are clouds in the sky. Antecedent and Consequent The antecedent for statement 3. is consequent is The antecedent for statement 4. is consequent is Check and the and the

Aggregate supply definitions The short-run aggregate supply curve shows: ? What happens to output in an economy when the government spends more money ? The relationship between the price level and aggregate expenditure ? What happens to output in an economy as the actual price level changes, holding all other determinants of real GDP constant ? How firms respond to changes in interest rates Which of the following are assumed to remain unchanged along a given short-run aggregate supply curve? Check all that apply. ? Real GDP ? Institutions, such as patent laws and tax systems, that make up the "rules of the game" ? The price level ? The position of the aggregate demand curve The term natural rate of unemployment refers to: ? The unemployment rate that occurs when an economy's real GDP is equal to its potential output The unemployment that arises due to purely seasonal factors, such as unemployed lifeguards in the winter The unemployment rate that would occur if there were no frictional unemployment The minimum possible unemployment rate for an economy

3) You are a research engineer working for a cancer research center. Your next set of experiments with clinical samples require the relative humidity of the laboratory to be greater than 75%. Just before the experiments, you measure dry and wet bulb temperatures, which found to be 25°C and 20°C, respectively. Determine, (a) the absolute (specific) humidity, (b) the relative humidity to see if you can start the experiments. (c) What would be the relative humidity if the lab temperature is reduced to 20°C with keeping the absolute humidity constant? Does this satisfy the required experiment condition? Assume an ambient pressure of 90 kPa and the specific heat at constant pressure is 1.005 kJ/kgC. Use data from the tables and do not use psychrometric chart to estimate the answers.

5. 1. The wearing parts of a coal mining machine are made of hardened tool steel, but are rarely, if ever, lubricated. The left and right wear plates for a typical tracked vehicle measure 60" long by 12" wide, and each tests at 360 HB. The vehicle weighs 12 tons. How far can it travel underground before each wear plate is reduced in thickness by 1/8"? Give the answer in miles. Steel Tracks Wear Plate
