What happens if you force magnets together? In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will […]
What is 98 100 as a percentage?
What is the density triangle?
What is the density triangle? The triangle is divided into three parts, with density occupying the top portion and mass and volume occupying the bottom two portions. The positions of each element of the triangle show us how they relate to one another through the formula above (Density = Mass / Volume, or ρ = […]
What is the function of hammer anvil stirrup?
What is the function of hammer anvil stirrup? Vibrations of the eardrum are in turn translated into oscillations of tiny bones (ossicles) found within the middle ear. The Hammer, Anvil, and Stirrup magnify the oscillations and relay this information to the chamber of the inner ear. What is a hammer in a ear? In ear […]
Which direction does a freely suspended magnet point to?
Which direction does a freely suspended magnet point to? A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction. Why does a freely suspended magnet? A freely […]
What is electric field and its SI unit?
What is electric field and its SI unit? Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces (or interactions) of nature. The derived SI units for the electric field are volts per meter (V/m), exactly equivalent to newtons per coulomb (N/C). What is SI unit of […]
What are the factors affecting thrust?
What are the factors affecting thrust? FACTORS AFFECTING THRUST The factors that affect the thrust of a gas turbine engine include air density, airspeed/ram effect and engine RPM. Why does thrust decrease as airspeed increases? The faster the aircraft speed, the less acceleration is being created on the intake air. Therefore thrust decreases with increasing […]
What is the difference between a desert and a savanna?
What is the difference between a desert and a savanna? savanna is tropical grassland with widely scattered trees or clumps of trees. A Desert is a biomein which the lack of precipitation limits plants growth; deserts are found in both temperate and tropical regions. What are the three types of prairies? Three types of prairie […]
Is hammer a metal or non metal?
Is hammer a metal or non metal? In contrast, materials like coal and sulphur are soft and dull in appearance. They break down into powdery mass on tapping with hammer. They are not sonorous and are poor conductors of heat and electricity. These materials are called non-metals. Can a hammer break metal? Because the hammer’s […]
What rollercoaster has the longest drop?
What rollercoaster has the longest drop? Kingda Ka How do drop towers slow down? And as Lenz’s law states, that magnetic field opposes the motion of the magnets. As a result, the magnetic field pushes up against the seat, causing the cart to slow down. This is how a drop tower ride’s magnetic brakes work. […]
