Which of the following is the correct formula for calculating the labor force participation rate?
Which of the following is the correct formula for calculating the labor force participation rate? The labor force participation rate is a measure of an economy’s active workforce. The formula for the number is the sum of all workers who are employed or actively seeking employment divided by the total noninstitutionalized, civilian working-age population. When […]
When a candle burns what chemical energy is converted?
When a candle burns what chemical energy is converted? The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy. Because when the candle […]
Is 20 Celsius hot or cold?
Why does atomic radius increase or decrease?
Why does atomic radius increase or decrease? Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius. This […]
Why is a water cycle called a cycle?
What is final temperature?
What is final temperature? Add the change in temperature to your substance’s original temperature to find its final heat. For example, if your water was initially at 24 degrees Celsius, its final temperature would be: 24 + 6, or 30 degrees Celsius. What was the effect of decreasing the copper’s mass? When you decreased the […]
What material reflects the most sunlight?
What material reflects the most sunlight? A “flat black” material having no glossy reflections absorbs the most solar energy. Conversely, light colors reflect more light than dark ones, and white reflects the most. What is a material that reflects light? If the surface is smooth and shiny, like glass, water or polished metal, the light […]
Why are Crash dummies so expensive?
Why are Crash dummies so expensive? To make things even more expensive, these evaluations require various sizes and shapes of crash test dummies. Meaning there has to be a test involving an average-sized male, female, child, and so forth. If each dummy costs upwards of $200,000, testing them all quickly becomes unbelievably expensive. Can you […]
What makes metallic bonds so strong?
What makes metallic bonds so strong? A metal is strong because when its structure is deformed by applied stress and the positive ions move, the delocalized electrons move as well, thus maintains their attraction to the positive ions. Metallic bond theory explains why metals have high thermal conductivity. How does a metallic bond work? Metallic […]
