Why do I feel sick during a storm? Approaching storms lower the air pressure. When atmospheric pressure decreases body tissues swell slightly. This can put increased pressure on joints and sinuses. Low temperatures also causes blood viscosity, or thickness. Does thunder affect mood? Thunderstorms are dramatic events, so it’s not surprising that they often bring […]
Is a change of temperature a chemical reaction?
Is a change of temperature a chemical reaction? A change in temperature is characteristic of a chemical change. If temperature increases, as it does in most reactions, a chemical change is likely to be occurring. This is different from the physical temperature change. During a physical temperature change, one substance, such as water is being […]
How do neutrons kill?
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 […]
Is it better to fast on full moon or new moon?
Why does binding energy decrease?
Why does binding energy decrease? The above figure illustrates that as the atomic mass number increases, the binding energy per nucleon decreases for A > 60. As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus. In other words, the BE/A has decreased. What […]
What are insulators short answer?
What are insulators short answer? Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good insulators. What are the uses of insulators? A thermos is an insulator used to keep liquids warm. Insulators work as protectors. They may protect heat, […]
Why is shale gas bad?
Why is shale gas bad? But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas. This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well. Is shale gas a renewable resource? Shale gas is non-renewable, and also polluting but […]
What are the three basic types of bridges?
What are the three basic types of bridges? Bridges can be found in a variety of shapes, but 3 basic designs rule the day; beam, arch, and suspension. What are the main parts of a bridge? The main components of a bridge are the foundation, substructure, and the superstructure. Each of these core areas have […]
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 […]
What causes automatic transmission to jerk when shifting?
What causes automatic transmission to jerk when shifting? Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues. Why does my car […]
