Do lighter objects reach terminal velocity faster? Yes. The terminal velocity of lighter objects tends to be lower, and thus reached faster with the same acceleration. Will heavier objects reach terminal velocity faster? heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight […]
How long can heat stroke affect you?
How long can heat stroke affect you? Complete recovery from heat stroke and its effects on body organs may take two months to a year. How do you treat a person with heat stroke and heat exhaustion? In most cases, you can treat heat exhaustion yourself by doing the following: Rest in a cool place. […]
What are three common defects of vision?
What are three common defects of vision? There are mainly three common refractive defects of vision. These are (i) myopia or near-sightedness (ii) Hypermetropia or far – sightedness (iii) Presbyopia. Can eye exercises reduce myopia? While myopia eye exercises won’t cure nearsightedness, they can help a person have their best possible vision and minimize eye […]
Will steam engines make a comeback?
Will steam engines make a comeback? Instead of making improvements in the existing steam technology, engineers were more attracted towards its replacement by diesel or electric traction. However, with the help of the scientific advancements in the past, the steam industry can be revived today and operate at its full potential. Who made the best […]
Can an object have constant non zero velocity and changing acceleration?
Can an object have constant non zero velocity and changing acceleration? “An object has constant non-zero velocity and changing acceleration.” Not possible, acceleration is the change of velocity. For velocity to remain constant the acceleration must remain zero. If acceleration is changing it might be zero at some point, but will not remain zero, so […]
What are the six signs of arson?
What are the six signs of arson? Common Signs of Arson A large amount of damage. No “V” burn pattern present, unsual burn patterns and high heat stress. Lack of accidental causes. Evidence of forced entry. Absence of valuable items. The same person shows up at unconnected fires. Low burning point with unidentifiable point of […]
What are the basic assumptions of the plate tectonics theory?
What are the basic assumptions of the plate tectonics theory? Two basic assumptions underlie the theory of plate tectonics: (1) The outermost shell of the Earth, called the lithosphere , rests on and is stronger than the immediately underlying layer, a layer of weakness called the asthenosphere . How does the plate tectonics theory affect […]
What are the products in this chemical reaction?
What are the products in this chemical reaction? They indicate the number of each chemical species that reacts or is formed. Methane and oxygen (oxygen is a diatomic — two-atom — element) are the reactants, while carbon dioxide and water are the products. All the reactants and products are gases (indicated by the g’s in […]
What is the example of opportunity cost?
What is the example of opportunity cost? When economists refer to the “opportunity cost” of a resource, they mean the value of the next-highest-valued alternative use of that resource. If, for example, you spend time and money going to a movie, you cannot spend that time at home reading a book, and you can’t spend […]
Why do we put antifreeze in car radiators in the summer and winter?
Why do we put antifreeze in car radiators in the summer and winter? A mixture of chemicals and water, antifreeze helps ensure that the liquid in our radiators doesn’t freeze in the winter or boil over in the summer (overheating the engine), and in doing so, it protects our engines from damage year-round. … What […]
