How do neutrons kill? Since neutrons are scattered and absorbed by air, neutron radiation effects drop off rapidly with distance in air. The intense pulse of high-energy neutrons generated by a neutron bomb is the principal killing mechanism, not the fallout, heat or blast. Does a neutron bomb exist? A neutron bomb is actually a […]
What reaction produces O2?
What reaction produces O2? When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. What is the product of 2H2 […]
What forces are used in a simple machine?
What is the principle of viscometer?
What is the principle of viscometer? These viscometers use the principle of ‘rotational viscometry’, i.e. their measurement of product viscosity is based upon immersing a specifically selected spindle within a sample of the product followed by measurement of the torque required to rotate the spindle at a set speed whilst immersed within the product sample […]
Who is the founder of functionalism psychology?
Who is the founder of functionalism psychology? William James Which is a behaviorist most likely to study? 240 Cards in this Set Of the following, a behaviorist is most likely to study: animal learning. Pavlov repeatedly paired a buzzer with the presentation of food and measured salivation to each. In this experiment the food was […]
What are macromolecules give 2 examples?
What are macromolecules give 2 examples? Plastics, resins, many synthetic and natural fibres (e.g., nylon and cotton), rubbers, and the biologically important proteins and nucleic acids are among many substances that are made up of macromolecular units. Insulin, a protein hormone, is an example of a macromolecule. What are some examples of macromolecules? Types of […]
Why is light red shifted?
Why is light red shifted? Light behaves like a wave, so light from a luminous object undergoes a Doppler-like shift if the source is moving relative to us. However, to be accurate, the red shifts observed in distant objects are not exactly due to the Doppler phenomenon, but are rather a result of the expansion […]
How long does it take to drive 120 miles at 60 mph?
What material absorbs sound waves?
What material absorbs sound waves? In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. Is styrofoam a good sound blocker? Polystyrene foams such as Styrofoam can help muffle and reduce the presence of any noises from […]
What is the danger zone for food in degrees?
What is the danger zone for food in degrees? The danger zone is the temperature range in which food-borne bacteria can grow. Food safety agencies, such as the United States’ Food Safety and Inspection Service (FSiIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C). What kind of salt do […]
