Is water displacement dependent on mass? The concept of Archimedes’ principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = […]

Do fires raise soil pH? The impact of fires on vegetation and wildlife is obvious. Nutrient levels and soil organic matter both increase after fire. Spanish research showed a significant increase in soil pH, carbon and nutrients immediately after a prescribed grass fire. How is soil affected by fire? The most dramatic effect of a […]

Which stars are the youngest? If proven, the newly discovered neutron star will be the youngest one known by humanity, beating the current youngest supernova remnant is Cassiopeia A, which is 330 years old that can be found 11,000 light-years away from Earth and can be found within our galaxy. Why doesn’t the helium core […]

Is oil a good energy source? Oil is particularly useful as a fuel because of its high energy density. As previously mentioned, the original energy source of oil is the Sun, as the energy stored within dead organic matter is what creates crude oil over time. Why is oil a bad energy source? Burning Fossil […]

How is wind speed indicated what is the unit used to define wind speed? How is Wind Speed and Direction measured? Wind speed is typically reported in miles per hour, knots, or meters per second. One mile per hour is equal to 0.45 meters per second, and 0.87 knots. Wind direction is typically reported in […]

What is a magnetic field how can the direction? the magnetic fields are the imaginary line which moves from south to north. this lines do not overlap each other. we can find the direction of the magnetic field lines by keeping a compass near to it. Why do 2 magnets repel or attract each other? […]

Does wind affect rain? Air Currents Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy […]

Does buoyancy affect weight? An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight […]

What is the most common type of corrosion on aircraft? Surface corrosion How do you fix aircraft corrosion? The methods normally used to remove corrosion are mechanical and chemical. Mechanical methods include hand sanding using abrasive mat, abrasive paper, or metal wool, and powered mechanical sanding, grinding, and buffing, using abrasive mat, grinding wheels, sanding […]
