Which property properties contributes to the high surface tension of water? Water has cohesive and adhesive properties. Cohesive forces are responsible for surface tension, the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water also has adhesive properties that allow it to stick to substances other than itself. Which […]

What is an example of the Fifth Amendment? During a criminal trial, the Fifth Amendment pertains to more individuals than just the defendant. For example, a witness may refuse to testify if doing so would have him or her self-incriminate, even if the criminal conduct in question is not related to the actual case. Why […]

What is the main magnetic field? The Main Magnetic Field originates from a dynamo process in the fluid outer core of the Earth. It strongly dominates over the various other contributions to the geomagnetic field, accounting for over 95% of the field strength observed at the Earth’s surface. What is the strength of an MRI […]

What is the speed of the particle when it enters the magnetic field region? A proton enters a uniform magnetic field of 1.0 × 10 −4 T 1.0 × 10 −4 T with a speed of. 5 × 10 5 m/s . Why does a magnetic field do not work on a charged particle? One […]

It is insoluble in water, but soluble in many organic solvents, such as benzene, ethanol, diethyl ether, carbon tetrachloride, chloroform. What is the […]

What are some examples of open and closed systems? Let us take simple examples. A closed system allows only energy transfer but no transfer of mass. Example: a cup of coffee with a lid on it, or a simple water bottle. An open system is one which can allow mass as well as energy to […]

What swim goggles do Navy SEALs use? We like these simple goggles – the Aqua Sphere Goggle . These are easy to slip on and knock out a 2k swim in the pool with fins or to get out in the ocean and get some distance. The glasses will serve their primary purpose, to keep […]

What is electric potential define electric potential and give its unit? It is defined as, An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration. Its SI unit is j/c=Volts. What do you mean by […]
