What are the purpose and effects of the parasympathetic nervous system? The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases […]
Is memory foam cancerous?
Is memory foam cancerous? Also, despite the fact that some of the chemicals that cause mattress off-gassing odors are classified as carcinogens or potential carcinogens, no studies have shown memory foam is toxic or causes cancer. What mattress do astronauts use? The Tempur-Pedic® /NASA Story The material, if successful, would significantly reduce the effects of […]
Why do electrons have spin?
Why do electrons have spin? Because electrons of the same spin cancel each other out, the one unpaired electron in the atom will determine the spin. There is a high likelihood for either spin due to the large number of electrons, so when it went through the magnetic field it split into two beams. What […]
Is francium used in bombs?
Is francium used in bombs? Because the alkali metals react viciously with water, a huge explosion will result when the two substances are combined, especially with the heavier alkalis like cesium and francium. This is the explosion necessary for our francium Bomb. First off, francium is highly rare. Why is francium dangerous? Useful to Scientists […]
How much is a curie of radiation?
What Colour surface is best at absorbing infrared radiation?
What Colour surface is best at absorbing infrared radiation? Dark What Colour is the best absorber of radiation? black How can you tell the difference between good and bad emitters of infrared radiation? Good emitters of IR (infra-red) radiation are also good absorbers. Matt, black surfaces are the best emitters and absorbers; and shiny, light […]
Is Colour change a physical or chemical property?
Is Colour change a physical or chemical property? Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is […]
What transverse wave has the shortest wavelength?
What transverse wave has the shortest wavelength? violet light Are light waves transverse? Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse […]
What is the principle of DC generator *?
What is the principle of DC generator *? DC generator operates on the principle of the dynamically induced electromagnetic force. When a conductor is placed in a varying magnetic field, an electromotive force gets induced within the conductor. This induced e.m.f magnitude is measured using the equation of the electromotive force of a generator. What […]
Can eating less meat help reduce climate change?
Can eating less meat help reduce climate change? In short, even if you aren’t already a vegetarian, cutting out some meat, especially red meat and large predatory fish, and eating lower on the food chain overall can help significantly lower your personal greenhouse gas emissions. Why is eating meat bad for environment? It causes climate […]
