Why is US 110 and Europe 220? Once AC was widely accepted as being superior to DC for power distribution, 110V became the standard for AC distribution presumably because it used the “safer” Voltage level of the DC system. After metal filament lamps became feasible, 220V became common in Europe because of the lower distribution […]
What important role does the sphenoid bone play in relation to the skull bones?
What important role does the sphenoid bone play in relation to the skull bones? Sphenoid bone has many essential functions. It helps form the base and lateral sides of the skull in combination with the orbital floor. Its many articulations with other bones give the skull rigidity. It is an attachment site for many of […]
How sound is produced very short answer?
How sound is produced very short answer? Sound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air, etc.) around it to vibrate thus producing sound. How is sound produced by human beings? […]
What is green computing and its advantages?
What is green computing and its advantages? 1) Green computing technique reduces the energy consumption which results into low carbon dioxide emission. 2) By using green computing techniques we can also save money that was spent in extra usage of energy and resources. 3) Green computing also applies changing government policy to encourage recycling. What […]
Why are macroscopic objects used in everyday life?
Why are macroscopic objects used in everyday life? matter waves for macroscopic bodies have very small wavelenghts. Accoding to Debroglie’s equation , wavelength is inversely proportional to mass of the object.As macroscopic bodies have large mass when compared to micro objects,they cannot exhibit wave property. Are matter waves electromagnetic in nature? (iv) The matter waves […]
What diseases can be treated by Crispr?
What diseases can be treated by Crispr? Eight Diseases CRISPR Technology Could Cure Cancer. One of the most advanced applications of CRISPR technology is cancer. Blood disorders. Blindness. AIDS. Cystic fibrosis. Muscular dystrophy. Huntington’s disease. Covid-19. How does Crispr work in humans? The CRISPR-Cas9 system works similarly in the lab. Researchers create a small piece […]
What are signs of parasympathetic nervous system?
What are signs of parasympathetic nervous system? The parasympathetic nervous system decreases respiration and heart rate and increases digestion. Stimulation of the parasympathetic nervous system results in: Construction of pupils. Decreased heart rate and blood pressure. What are the symptoms of an overactive nervous system? Symptoms may include: Persistent or sudden onset of a headache. […]
Which atom model is used today?
Which atom model is used today? Bohr model Why was Bohr model accepted? His model identified more clearly where electrons could be found. Although later scientists would develop more refined atomic models, Bohr’s model was basically correct and much of it is still accepted today. It is also a very useful model because it explains […]
Does UV increase with temperature?
Does UV increase with temperature? As the sun rises, the level of UV increases until it reaches its peak at solar noon, when the sun is directly above us. It’s often the cooler days that result in the worst sunburns because the UV level is high while the temperature is not. Damaging UV is invisible […]
What happens when two waves meet on the same side?
What happens when two waves meet on the same side? Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the […]
