How does air resistance affect cars? Air friction does not significantly affect a car’s gas mileage. Cars are slowed down when they stir up the air too much. Stirring up the air creates vortices and billows that take energy away from the car. This effect is known as “wake drag”, “pressure drag”, or “form drag”. […]

How do you tell if you have had a seizure? General symptoms or warning signs of a seizure can include: Staring. Jerking movements of the arms and legs. Stiffening of the body. Loss of consciousness. Breathing problems or stopping breathing. Loss of bowel or bladder control. Falling suddenly for no apparent reason, especially when associated […]

What causes light beams to be parallel?
What causes light beams to be parallel? A narrower beam of laser light spreads out more quickly than a wider beam. Only an infinitely wide beam (a plane wave) does not spread out, and therefore has parallel waves. Divergence is observed by shining a laser light on a wall and then seeing the spot grow […]
What allows to float?
What allows to float? Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. When an object floats, it pushes water out of the […]
Do electrons physically move?
Do electrons physically move? Electrons do physically move when a voltage is applied – extremely slowly. This works out to 8.4 cm/hour. Can an electron move? Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency. Furthermore, an electron in a stable atomic state does not move […]
Does direction matter measuring momentum?
Does direction matter measuring momentum? Direction does not matter when you are measuring momentum. Momentum can be transferred from one object to another. When objects collide, some momentum is lost. What is the difference between momentum and velocity? As nouns the difference between velocity and momentum is that velocity is (physics) a vector quantity that […]

Is sound a standing wave?
Is sound a standing wave? Standing sound waves open and closed tubes. Sound waves are longitudinal waves in a medium such as air. The loudness or volume of the sound also increases with wave amplitude. In open and closed tubes, sounds waves can exist as standing waves as long as there is at least one […]
What will the era be called when William is King?
What will the era be called when William is King? William certainly has the option of choosing a new regnal name when he becomes King (perhaps one of his middle names: Arthur, Philip, or Louis, or George, like his great-grandfather), but if he keeps William, he would be known as King William V. What will […]
