Which of the following is the most usable form of energy for future? Energy Business Review lists the world’s most used energy sources based on the share of each source to global energy consumption in the past five decades according to BP’s estimates. Oil has been historically the world’s most used energy source accounting for […]

What is the CMS system? A Content Management System, or CMS, is a piece of software designed to help users create and edit a website. They have evolved to help design the look of websites, track user sessions, handle searches, collect visitor comments, host forums and much much more. What is CMS LHC? The Compact […]

What are the rules for swimming? swimmer must break the surface. throughout the race. • May be completely submerged. during turn. • Arms in same horizontal. plane; •Elbows can be out at turn. and finish; •Head must break surface by. widest part of 2nd stroke; •One single butterfly/dolphin. each turn at any time prior to. […]

Is it OK to run anaerobic? If you keep running for too long in this anaerobic state, you will have to slow down significantly or stop. But if you are running for a realistic time goal, and are pacing yourself correctly, you should only be running anaerobically for a short period of time, at the […]

Which is more elastic glass or steel? The Coefficient of elasticity of glass is between 50 and 90; the Coefficient of elasticity of steel is 210; the Coefficient of elasticity of Copper is 120. Therefore, the rubber is more elastic than glass and glass is more elastic than copper and copper is more elastic than […]

What month do geese fly south? Late spring or early summer is typically when you’ll notice geese flying north in that famous V pattern (which they use to save energy as it reduces wind drag on the geese not at the tip of the V). September and early November is typically when geese begin flying […]

Is it possible for a car to move at constant speed and be accelerating? The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity […]

Can you fly through a tornado? Flying through a tornado could destroy an airplane; pilots avoid all thunderstorms — particularly those producing tornadoes — by a wide margin. Is a tornado more dangerous than a hurricane? While both types of storms are capable of producing destructive winds, tornadoes can become stronger than hurricanes. The most […]

Can a tsunami tip over a cruise ship? Experts agree that a cruise ship sailing out over a body of water is not likely to feel any impacts from a tsunami’s waves. Cruise ships closer to land or at port would face an immense threat from the tsunami’s tall, high-energy and potentially devastating wave. Can […]

What will happen if the air pressure increases? For example, if air pressure increases, the temperature must increase. If air pressure decreases, the temperature decreases. It also explains why air gets colder at higher altitudes, where pressure is lower. Which prediction is most likely when the air pressure increases? If air pressure rises, a high […]
