How do beaches disappear? When seas rise, it’s inevitable — beaches disappear. Add human interference with natural beach topography — channel dredging, sand replacement, seawalls, jetties — and it’s a recipe for disaster. Here are 10 notable beaches in need of saving. Does sand look and feel the same wherever you go? “The sand on […]
What has the greatest effect on plate movement?
What has the greatest effect on plate movement? Scientists still debate over which of these forces has the greatest effect on plate motion. Convection currents in the mantle produce a force that causes motion called basal drag. Rising mantle material at mid-ocean ridges creates the potential for plates to move away from the ridge with […]
Are houses wired in series or parallel?
Are houses wired in series or parallel? Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit. […]

In the event that a dispute occurs during a match, you’ll be able to settle it. For instance, your opponent may gain an […]
What is the current in the wire?
What is the current in the wire? Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time. Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the […]
How strong of a magnet Do I need to magnet fish?
How strong of a magnet Do I need to magnet fish? Pulling force of at least 500lbs (226kg) If you’re just starting out, start with a 500lbs capable magnet. This will satisfy the majority of hauls without feeling like you’re missing out. 500lbs is still a very strong magnet. If you want to get any […]
Does Matter diffract?
Does Matter diffract? All matter exhibits wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. In most cases, however, the wavelength is too small to have a practical impact on day-to-day activities. Why can’t particles diffract? From the standpoint of classical physics, diffraction […]
What is the function of base course?
What is the function of base course? Under rigid pavements, the base course is used to: (1) provide uniform and stable support, (2) minimize damaging effects of frost action, (3) provide drainage, (4) prevent pumping of fine-grained soils at joints, (5) prevent volume change of the subgrade, (5) increase structural capacity of the pavement, and […]
What does the slope of a distance-time graph indicate?
What does the slope of a distance-time graph indicate? The slope of the distance-time graph indicates speed. It is because the slope of a distance-time graph determines the speed of that body, so the steeper the slope greater will be the speed of the body. What is a symbol for time? Symbols for physical quantities […]
What voltage do Tesla cars run on?
What voltage do Tesla cars run on? about 375 volts and 350 volts Which of the following is recommended for working on high voltage vehicles? 48V systems are most preferable for electric 2W and 3W and vehicles like Mahindra Treo and Ather 450 fall in this category. For electric 4Ws, the range is generally between […]
