What sound frequency travels the farthest? In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Does bass travel up or down? In short, sound is omnidirectional, meaning that it can travel in all directions, including up and down. So, as you can see, while […]
What is the compression ratio for 93 octane?
What is the compression ratio for 93 octane? 9.5:1 What is the best compression ratio for a turbo engine? How much compression does a turbo add? Turbos typically add about 10 to 15 psi boost which is about 1 atmosphere pressure (1 atmosphere is 14.5 psi), so air enters the cylinders at a maximum pressure […]
Which is the best description of an alpha particle?
Which is the best description of an alpha particle? Alpha particle, positively charged particle, identical to the nucleus of the helium-4 atom, spontaneously emitted by some radioactive substances, consisting of two protons and two neutrons bound together, thus having a mass of four units and a positive charge of two. What is the symbol of […]
Is mass equal to weight?
Is mass equal to weight? In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on […]
Is height positive or negative?
Is height positive or negative? An object’s height is a property of that object and has nothing whatsoever to do with the object’s motion. It’s correct to speak of the object’s displacement when describing motion. “Negative height” is always a meaningless term. Without specifying a coordinate system, “negative displacement” is almost as useless. Can work […]
What rules are applied in balancing equations?
What rules are applied in balancing equations? Balancing Chemical Equations Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation. What 4 guidelines […]
What is heat budget explain with the help of diagram?
What is heat budget explain with the help of diagram? A heat budget is the perfect balance between incoming heat absorbed by earth and outgoing heat escaping it in the form of radiation. If the balance is disturbed, then earth would get progressively warmer or cooler with each passing year. What is heat budget class […]
When supply increases what happens to price?
When supply increases what happens to price? There is an inverse relationship between the supply and prices of goods and services when demand is unchanged. If there is an increase in supply for goods and services while demand remains the same, prices tend to fall to a lower equilibrium price and a higher equilibrium quantity […]
How do you calculate the number of rivets needed?
What are 3 reasons for the seasons?
What are 3 reasons for the seasons? The reasons for the Earth experiencing seasons are revolution, rotation, tilt, axial parallelism, and sphericity – yikes! and I thought it had only to do with the tilt of the Earth! Let’s first look at revolution, which is Earth’s orbit around the sun. What are the 3 reasons […]
