write down the method adopted by in ancient times by sailors on ships and travellers in the desert to reach their destination? 1. Celestial Navigation: This method used the position of the stars, sun and moon to determine the direction of travel. 2. Dead Reckoning: This method used the ship’s speed and direction to estimate …

A magnetic compass is a navigational instrument used to determine direction relative to the Earth’s magnetic poles. It consists of a magnetized pointer (usually marked on the North end) free to rotate on a pivot, making it possible to align itself with the Earth’s magnetic field. It is one of the oldest navigational tools, used …

Maglev trains use magnetic levitation to suspend, guide and propel vehicles with magnets rather than using mechanical methods, such as wheels, axles and bearings. This form of transportation is still in its early stages, but it has the potential to revolutionize the way people travel. The technology is based on the principle of magnetic repulsion …

A lodestone is a naturally magnetized piece of the mineral magnetite. It is a form of iron oxide with strong magnetic properties that it has possessed naturally since its creation by natural processes. It was used as an early form of a compass by the Chinese in the Han Dynasty and was widely used in …

Nature Magnet: Nature magnetic fields are created by the Earth’s core, which is composed of iron and nickel. These fields are naturally occurring and very weak. Artificial Magnet: Artificial magnetic fields are created by man-made objects like magnets. They are much stronger than natural magnetic fields, and can be used for a variety of purposes …

1. Magnetic Resonance Imaging (MRI): MRI uses strong magnetic fields and radio waves to create detailed images of the organs and tissues inside the body. 2. Hall Effect: This experiment is used to measure the strength and direction of a magnetic field by using a thin metal plate. 3. NMR Spectroscopy: This experiment is used …

The primary disadvantage of friction is that it can cause wear and tear on surfaces, leading to increased maintenance costs. In addition, it can cause objects to move more slowly than they would without friction, reducing efficiency. Finally, friction is often a source of unwanted noise and heat.

Area increase pressure decrease . Find situation where the principle is applied ? 1. Weather patterns: As atmospheric pressure decreases due to an increase in area, wind speeds increase. 2. Oceanography: As surface area increases, pressure from the atmosphere decreases, resulting in lower ocean depths. 3. Automotive engineering: As the area of the piston in …
