How much is a curie of radiation? One curie (1 Ci) is equal to 3.7 × 1010 radioactive decays per second, which is roughly the amount of decays that occur in 1 gram of radium per second and is 3.7 × 1010 becquerels (Bq). In 1975 the becquerel replaced the curie as the official 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 […]
What are the purpose and effects of the parasympathetic nervous system?
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 […]
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 […]
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 […]
What happens if an egg does not fertilize?
What happens if an egg does not fertilize? If the egg is not fertilized or does not implant, the woman’s body sheds the egg and the endometrium. This shedding causes the bleeding in a woman’s menstrual period. When a fertilized egg does implant, a hormone called human chorionic gonadotropin (hCG) begins to be produced in […]
What are the applications of soft and hard magnetic materials?
What are the applications of soft and hard magnetic materials? They are used in electrical rotating machine, electromagnet, electrical machine and transformer. It is used in communication equipment such as audio transformer, recording heads and magnetic modulators because of high initial permeability in feeble fields. They also possess low hysteresis and eddy current losses. Which […]
