Will a magnet stick to real silver? “Silver is not noticeably magnetic, and exhibits only weak magnetic effects unlike iron, nickel, cobalt, and the like,” says Martin. “If your magnet sticks strongly to the piece, it has a ferromagnetic core and is not silver.” Fake silver or silver-plated items are generally made of other metals. […]
Does light travel faster in glass than in water?
Does light travel faster in glass than in water? In water, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water, than it travels through glass. Why does light pass through glass? Photons pass through glass because they are not absorbed. And they are not absorbed because there […]
What happens when gas volume increases?
What happens when gas volume increases? If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the […]
What are the 2 main characters used for matching the pattern?
What are the 2 main characters used for matching the pattern? In SQL, the LIKE keyword is used to search for patterns. Pattern matching employs wildcard characters to match different combinations of characters. The LIKE keyword indicates that the following character string is a matching pattern. Is used for pattern matching? Generally, the REGEXP_LIKE(column_name, ‘regex’) […]
Which best describes the protection efforts for coral reefs?
Which best describes the protection efforts for coral reefs? Answer. Answer: Minimize use of fertilizers. Can the coral reefs be saved? Active and targeted restoration by creating new ways to outplants many corals at once and other interventions will reduce the decline of coral populations and support coral reef ecosystems in changing environmental conditions. Monitoring, […]
What happens to extra electrons in a charged object when it becomes grounded?
What happens to extra electrons in a charged object when it becomes grounded? Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of […]
When waves pass through an opening or around a corner the waves bend as they pass the corners?
When waves pass through an opening or around a corner the waves bend as they pass the corners? Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and […]
Will the next force be equal to zero?
What are the components of centripetal force?
What are the components of centripetal force? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force […]
