What are the 3 main stages of cellular respiration?
What are the 3 main stages of cellular respiration? Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. What is the cellular respiration process? Cellular respiration, the process by which organisms combine oxygen […]
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 […]
Which type of telescope is best?
Which type of telescope is best? As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than […]
How do you calculate perihelion distance?
How do you calculate perihelion distance? The perihelion distance P=a(1−e) and the aphelion distance A=a(1+e) where e=0.875 is the eccentricity. This gives a perihelion distance of 2.375AU and an aphelion distance of 35.625AU. Is Kepler’s third law correct? Kepler’s third law provides an accurate description of the period and distance for a planet’s orbits about […]
How does air resistance affect cars?
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?
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 […]
Can two waves with different frequencies interfere?
Can two waves with different frequencies interfere? 2 Answers. No; wave interference takes place whenever two waves of any frequency, same, nearly the same or widely different interact. An air molecule next to your ear, for example, can only respond to the sum of all the different sound waves reaching it at any moment. What […]
Is it rude to say here you go?
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 […]
