What are the two major types of seismic waves? There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. What are the slowest seismic waves? The slowest waves, surface waves, arrive last. They […]
What happens to electrons when they reach a light bulb?
What happens to electrons when they reach a light bulb? 2 Answers. Electrons are accelerated by the field inside the incandescent filament (the voltage drop over the light bulb is large, the field is relatively strong). The electron then interacts with the lattice, losing its energy to thermal vibrations. Then gets accelerated again, etc. Is […]
What are the three main characteristics of matter?
What are the three main characteristics of matter? Three States of Matter Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. Liquid matter is made of more loosely packed particles. Gaseous matter is composed of particles packed so loosely that it has neither […]
How expensive is a dock?
How expensive is a dock? On average, expect to pay $8,000 to $30,000 for a standard sized permanent boat dock. For a very small dock, you may get away with paying as little as $5,000. Piling docks cost $20 to $40 per square foot including installation. The most expensive types of docks usually max out […]
What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
What is the most powerful erosional agent?
What is the most powerful erosional agent? Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. What is the concept of graded stream? A […]
What are two requirements for current flow?
What are two requirements for current flow? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper […]
Is friction necessary for a body to roll?
Is friction necessary for a body to roll? Yes friction is necessary to the body to roll. The minimum friction is that when the body moves easily by using 1 Newton of force. How is the draft calculated in rolling? Explanation: During rolling process, the workpiece gets squeezed, causing the thickness of the workpiece to […]
