What proves a permanent magnet? A high magnetic ordering temperature (called the “Curie temperature” or Tc), below which the material is spontaneously magnetic. A large remanent magnetic flux (called “remanence” or Br) maintained in the absence of an external magnetic field. A strong resistance to demagnetization (called “coercivity” or Hc) What is the strength of […]
Which bird can fly without flapping wings?
Which bird can fly without flapping wings? albatross Do birds sleep while flying? Due to the lack of studies monitoring the sleep patterns of flying birds, these hypotheses had previously been left unconfirmed. Now, however, according to a new study from the Max Planck Institute for Ornithology, researchers have finally found evidence that birds do […]
How do you trick a motion sensor?
How do you trick a motion sensor? Most motion detectors, even newer ones, use infrared to detect significant changes in the surrounding room’s temperature, Porter said. Normally, walking around in a room would set off these sensors, but using something as simple as a piece of styrofoam to shield your body can trick them, he […]
What is solenoid what is the direction of lines of force around it?
What is solenoid what is the direction of lines of force around it? Turning the solenoid around means that all field lines either point outwards or they all point inwards. Moving the solenoid along the axis means this happens for every little bit of the solenoid. But if all the field lines point outwards everywhere, […]
Why doesnt horizontal motion affect vertical motion?
Why doesnt horizontal motion affect vertical motion? The horizontal velocity remains constant, because there is no acceleration in that direction. The length of the horizontal velocity vector doesn’t change. THE VERTICAL & HORIZONTAL MOTIONS ARE INDEPENDENT. THE HORIZONTAL VELOCITY DOES NOT AFFECT THE VERTICAL MOTION. Does velocity change with angle? When an object is projected […]
What is say is a path of electricity one word answer?
What is say is a path of electricity one word answer? An electric circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the “source” of electrons. Is a closed path that allows electricity to flow from one point to […]
What is reverse causality example?
What is reverse causality example? According to Katz (2006), identifying reverse causality is sometimes a matter of “common sense.” For example, a study might find that brown spots on the skin and sunbathing are linked. While it is plausible that sunbathing can cause brown skin spots, it’s highly unlikely that the brown spots cause sunbathing. […]
