Where is the magnetic field the weakest? The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet. Where do magnetic fields come from? The magnetic […]
What is quantum wire in nanotechnology?
What is quantum wire in nanotechnology? Quantum wires are extremely narrow structures where electron transport is possible only in a very few transverse modes (with energies less than the Fermi energy). Quantum wires can be used as electron waveguides. Semiconductor quantum wires have been used to make switchable high-speed lasers. How do you prove energy […]
Who is bigger Saturn or Jupiter?
Who is bigger Saturn or Jupiter? Saturn is the second largest of the gas giants; with a mean diameter of 120,536 km, it is just slightly smaller than Jupiter. However, it is significantly less massive than its Jovian cousin, with a mass of 569 x 1024 kg (or 569,000,000,000 trillion metric tons). Who is stronger […]
What made the Tertiary Period unique?
What made the Tertiary Period unique? Tertiary Climate: A Cooling Trend From Tropics To Ice Age The beginning of this period was very warm and moist compared to today’s climate. Much of the earth was tropical or sub-tropical. Palm trees grew as far north as Greenland! By the middle of the tertiary, during the Oligocene […]
How far can a rubber band stretch?
How far can a rubber band stretch? This means that if I stretch the rubber band a distance of about 20 centimeters (that’s around the breaking point) then there would be 1.8 Joules of energy stored in it. How much force can a rubber band withstand before breaking? The rubber piece will stretch, but not […]
What virus attacks the nervous system?
What virus attacks the nervous system? Viruses that infect the central nervous system (brain and spinal cord) include herpesviruses (see also herpes simplex virus infections), arboviruses, coxsackieviruses, echoviruses, and enteroviruses. What happens when your immune system attacks your nervous system? Guillain-Barre (gee-YAH-buh-RAY) syndrome is a rare disorder in which your body’s immune system attacks your […]

What are the advantages of laminar flow?
What are the advantages of laminar flow? The principle of laminar flow was first discovered in 1960; laminar flow workstations are used to move air safely through laboratory enclosures. They direct unrestricted airflow towards sterility, prevent contamination, and reduce potential turbulence. What is the principle of laminar flow? A laminar flow unit creates dust free […]
Is a banana turning brown a physical or chemical change?
Is a banana turning brown a physical or chemical change? (d) A banana turning brown is a chemical change as new, darker (and less tasty) substances form. What type of chemical reaction is rotting fruits? enzymatic reaction Why are bananas gassed? “Bananas make other fruit ripen because they release a gas called ethene (formerly ethylene),” […]
Why is self-interest bad?
Why is self-interest bad? Selfish individuals may act in a manner that’s detrimental to others. Having a healthy self-interest doesn’t preclude caring about others. As a result, you may feel guilty about acting in your own self-interest. The reasoning is that taking care of your needs will invariably have a negative impact on someone else. […]
