What usually keeps two unlike air masses separate when they meet? When two large air masses meet, the boundary that separates them is called a front, and the properties of air masses are determined by the the underlying surface properties where they originate. What causes air masses to move? Winds and air currents cause air […]
Does higher voltage mean longer battery life?
Does higher voltage mean longer battery life? A higher voltage battery has the potential to “push” more current–that is, more electrons–for a given resistance. This translates to the capacity for greater work, which is the same thing as more power. Higher voltage also means less current to do the same amount of work, so longer […]
What is the effect of surface area on enzyme action?
What is the effect of surface area on enzyme action? Conclusion: It was concluded that surface area, temperature and pH levels all had significant influence on the rate of enzymatic activity. As surface area of substrate increased, the rate of reaction had also increased and vice versa. How does increasing surface area increase rate of […]
What is fill factor formula?
What is fill factor formula? The “fill factor”, more commonly known by its abbreviation “FF”, is a parameter which, in conjunction with Voc and Isc, determines the maximum power from a solar cell. The FF is defined as the ratio of the maximum power from the solar cell to the product of Voc and Isc […]
Why must mixtures and compounds be separated in different ways?
Why must mixtures and compounds be separated in different ways? The prime difference lies in the fact that pure substances cannot be physically separated while mixtures can be. A pure substance, any compound or element, can’t be separated into different atoms by physical methods. A chemical reaction must occur to separate a compound into its […]
What are the negatives of carbon?
What are the negatives of carbon? Carbon-negative: This means removing CO₂ from the atmosphere, or sequestering more CO₂ than is emitted. This might include a bioenergy process with carbon capture and storage. Low emissions: Generating greenhouse gases at a lower rate than business as usual. What are the disadvantages of carbon capture? Another drawback is […]
What will happen if we destroy the forest?
What will happen if we destroy the forest? When we destroy forests, we add to climate change because forests trap carbon and help stabilise the world’s climate. When forests are trashed, the carbon trapped in trees, their roots and the soil is released into the atmosphere. Deforestation accounts for up to 20% of all carbon […]
How many bonding sites does oxygen have?
How do you phrase a hypothesis?
How do you phrase a hypothesis? However, there are some important things to consider when building a compelling hypothesis. State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment. Try to write the hypothesis as an if-then statement. Define the variables. […]
Under what conditions is it possible to increase production of one good without decreasing production of another good?
Under what conditions is it possible to increase production of one good without decreasing production of another good? 5. (Production Possibilities) Under what conditions is it possible to increase production of one good without decreasing production of another good? An economy can produce more of one good without sacrificing production of another good if it […]
