Is a survey a secondary source? Primary sources are the original documents of an event or discovery such as results of research, experiments or surveys, interviews, letters, diaries, legal documents, and scientific journal articles. diaries and letters. academic articles reporting NEW data and findings. What is secondary data analysis examples? They might search through periodicals, […]
How can we increase the strength of magnetic field of solenoid?
How can we increase the strength of magnetic field of solenoid? Strength of a Solenoid Adding more turns to the coil of wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field. What is solenoid mention two ways to increase? Two […]
What is the co2 ppm today?
What is the co2 ppm today? 415.46 ppm Units = parts per million (ppm). What is the level of co2 in the atmosphere today? The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today […]
How does a photon interacts with matter?
How does a photon interacts with matter? In a pair-production interaction, the photon interacts with the nucleus in such a manner that its energy is converted into matter. The interaction produces a pair of particles, an electron and a positively charged positron. These two particles have the same mass, each equivalent to a rest mass […]
Why is energy released in a fission reaction?
Why is energy released in a fission reaction? Fission is the splitting of heavy nuclei (such as uranium) – in two smaller nuclei. This process needs less energy to ‘bind’ them together – so energy is released. The larger nuclei again needs less energy to hold it together – so energy is released. What is […]
What will happen to the pressure of a contained gas if its temperature is lowered?
What will happen to the pressure of a contained gas if its temperature is lowered? How does a decrease in temperature affect the pressure of a contained gas? The pressure decreases because the kinetic energy decreases with the temperature and slower moving particles impact the walls of a contain with less energy. Which three factors […]
Which types of muscle tissue are involuntary?
Which types of muscle tissue are involuntary? Muscle Types: Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary. What is an example of an involuntary muscle? These muscles can be defined as the muscles that functions or contracts […]
What clues did you use to put the continents together?
What clues did you use to put the continents together? Wegner’s Evidence for Continental Drift Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of today’s continents and landmasses to form the supercontinent Pangea. Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean […]
Is 30 degrees water hot?
What is the electron group geometry of cl2o?
What is the electron group geometry of cl2o? Structure. The structure of dichlorine monoxide is similar to that of water and hypochlorous acid, with the molecule adopting a bent molecular geometry (due to the lone pairs on the oxygen) and resulting in C2V molecular symmetry. How many electron groups are in SF2? Each bond uses […]
