New employees at Avondale Industries’ unmanned systems production line in Denver, CO, participate in employee training under the direction of the training and development department, but the line managers conduct the actual training. During the last two trainings, the line managers cut the sessions short and explained that the employees would receive better training while working on the production line. The trainer responsible for the program understood the line managers’ viewpoint about developing skills used on the line but needed them to see that training should provide more than just developing those specific skills. Which of the follow statements best explains why training should provide a longer-term view than just teaching line workers the skills needed to perform satisfactorily in their current jobs?     Giving line workers expanded training helps them understand more than specific skills; it also helps them become more confident contributors.   Training with a…

What materials will the teacher and the students need to complete a lesson on mixing substances in a 5th grade classroom based on the below standard and learning objective? Standard Conduct an investigation to determine whether the mixing of two or more  substances results in new substances.  Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.

A chef in Denver (the mile high city) and a chef in Tampa (sea level city) make the same recipe but the Denver chef has to modify the recipe. Why did the Denver chef have to modify the recipe? O The density of water is higher at high altitudes O The boiling point of water is lower at high altitudes O The boiling point of water is higher at high altitudes O The density of water is lower at high altitudes D Question 9 Which statement describes how food is cooked using microwaves? O The food reflects microwaves causing the air surrounding the food to heat up O Microwaves heat up the air around the food and it is transferred to the food through convection O Microwaves break chemical bonds and the energy that is released cooks the food O The food absorbs the microwaves and its molecules begin to rotate causing heat D Question 10 When making yogurt, the pH of the milk solution O decreases, making it more sour O No answer text provided. O stays the same O increases, making it more bitter

Question 19

A group of students performed a melting point experiment to study the physical properties of ionic and covalent solids. The data collected are shown in the table.  Solid Sample Melting Point (oC)  Time Elapsed (min) Table Sugar (sucrose) 186 18 Table Salt (sodium chloride) 500 (not observed) 30  Paraffin Wax 37 4  Vegetable Lard 50 >5 Using the information contained in the table, what is the BEST explanation for the results?A    The melting point of sodium chloride was not observed because ionic solids do not melt, whereas sugar, wax, and lard melted because they are softer than salt.B    The melting points of covalently bonded solids tend to be lower than ionic solids. The melting point of sucrose was greater than the wax or the lard because sucrose has stronger bonds than wax or lard.C    The melting point of sodium chloride was not observed because ionic solids are composed of positive and negative ions that do not melt; whereas, the…
