When someone does the opposite of what they say? “Contra-” usually means “against,” and to contradict is to go against or say the opposite of what someone else is doing or saying. Sometimes to contradict is to frustrate with words, like when one person says “The sky is blue” and another says “No, it’s azure.” […]
Can I drill above a plug socket?
Can I drill above a plug socket? Don’t drill directly above or below light switches and plug sockets. Invest in a stud finder/metal detector (as mentioned above) that will detect wires and pipes. If you do mistakenly drill into a water pipe, think of the little boy with his thumb in the dyke and LEAVE […]
What happens when you mix oxygen and magnesium?
What happens when you mix oxygen and magnesium? When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO). What happens when […]
What is the 1st 2nd and 3rd line of defense?
What is the 1st 2nd and 3rd line of defense? In the Three Lines of Defense model, management control is the first line of defense in risk management, the various risk control and compliance over- sight functions established by management are the second line of defense, and independent assurance is the third. What is the […]
Why can you compress gas but not liquid?
Why can you compress gas but not liquid? There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space […]
What are the most critical factors responsible for the ecosystem changes?
What are the most critical factors responsible for the ecosystem changes? The most important direct drivers of change in ecosystems are habitat change (land use change and physical modification of rivers or water withdrawal from rivers), overexploitation, invasive alien species, pollution, and climate change. What are the factors that disrupt the balanced ecosystem? FACTORS AFFECTING […]
What is the largest immigrant group in Canada?
What is the largest immigrant group in Canada? The five largest foreign-born groups in Canada, including those from the United Kingdom, China, India, Italy, and the United States, account for 33 percent of the total immigrant population.

What is the kinetic energy of a 44 kg cheetah running at 31 m s?
What are the 4 types of sand dunes?
What are the 4 types of sand dunes? These are the barchan, transverse, blowout, linear, and composite dunes. Although it is sometimes easier to see different dune types from the air, some deserts have only one predominant type. The barchan dune is a horseshoe-shaped dune with the front curve facing into the wind. What is […]
Is there any flux in the solenoid?
Is there any flux in the solenoid? A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. “Displacement Current” is the name given by physicists to an imaginary current which is really just a time-varying electric flux through some […]
