What causes change in season? The Short Answer: Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the […]
How do you break the current in a circuit?
How do you break the current in a circuit? The most common way to measure current in a circuit is to break the circuit open and insert an “ammeter” in series (in-line) with the circuit so that all electrons flowing through the circuit also have to go through the meter. What happens when there is […]
How is a continuous spectrum formed?
How is a continuous spectrum formed? Continuous spectra (also called thermal or blackbody spectra) arise from dense gases or solid objects which radiate heat. They emit radiation over a broad range of wavelengths, thus the spectra appear smooth and continuous. What is the origin of continuous spectrum? The line spectrum of an element originate when […]
Which sea has lowest salinity?
Which sea has lowest salinity? The Arctic Ocean’s What is salinity of ocean water? about 35 parts per thousand What ocean has the highest salinity? Atlantic Ocean What Happens When ocean salinity drops? Changes in salinity could also affect water currents because saltwater is denser than fresh water and sinks. Warmer air can absorb more […]
What percentage of fuel energy is actually converted to electrical energy?
What percentage of fuel energy is actually converted to electrical energy? What approximate percentage of energy in the fuel is converted to electricity? Explanation: Only 34% of the energy stored in the fuel is converted to electricity & 66% is lost. The maximum loss of energy takes place in the condenser where heat is rejected […]

What are three major branches of natural science?
What are three major branches of natural science? Three Branches of Natural Science: Physical, Earth & Life. What are the three areas of life science? Therefore, life science is divided into many fields, such as ecology, botany, and zoology. Two theories underlie all of the fields of life science: the cell theory and the theory […]
What type of energy is used in an electric car?
What type of energy is used in an electric car? AEVs (all-electric vehicles) are powered by one or more electric motors. They receive electricity by plugging into the grid and store it in batteries. They consume no petroleum-based fuel and produce no tailpipe emissions. Do electric cars contribute to global warming? Plug-in electric vehicles (also […]
Is aluminum oxide toxic to humans?
Is aluminum oxide toxic to humans? Aluminium oxides rank amongst the less toxic substances and only exhibit toxic effects in high concentrations. However, the oral intake of aluminium oxide over a long time period should be avoided as elevated aluminium levels in the blood could cause side effects on human health. What is Al2O3 called? […]
What is the sequence of vessels that blood travels as it leaves the heart?
What is the sequence of vessels that blood travels as it leaves the heart? Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to […]
