How does speed affect projectile motion? Because air resistance affects the horizontal component of a projectiles trajectory, the effect of it can be minimized by lowering the angle of release. Speed or velocity is directly related to distance. The greater the speed of release, the greater the distance covered in flight. Initial Horizontal Velocity. How […]
What is the value of the spring constant k?
What organs help the digestive system?
What organs help the digestive system? The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Helping them along the way are the pancreas, gall bladder and liver. Here’s how these organs work together in your digestive system. Which […]
Is a higher moment of inertia better?
Is a higher moment of inertia better? Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. Masses that are further away form the axis of rotation have the greatest moment of inertia. What is […]
What is the evidence for Pangea?
What is the evidence for Pangea? Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. Why did people […]
What is SI unit of merit?
What is SI unit of merit? Figure of merit is the amount of current been passed in the unit of deflection in a galvanometer. Its SI unit is Ampere per division. What’s the difference between a galvanometer and a multimeter? The galvanometer is converted into the ammeter by connecting the resistance in parallel with the […]
How do you explain pressure altitude?
How do you explain pressure altitude? Pressure altitude is the attitude displayed on the altimeter when the Kollsman window is set to 29.92 inches of mercury, or 1013.4 millibars. Pilots cannot use pressure altitude below 18,000 feet, because then the aircraft’s true altitude would change depending on temperature. Why do we calculate pressure altitude? Pressure […]
What does it mean if a mineral has a crystal structure?
What does it mean if a mineral has a crystal structure? Minerals are crystalline solids. A crystal is a solid in which the atoms are arranged in a regular, repeating pattern (Figure below). The pattern of atoms in different samples of the same mineral is the same. What Crystal has 4 sides? Hexagonal System What […]
