Is the bottom of the wave? The bottom of a wave is called the trough. The distance between two consecutive crests or two consecutive troughs is the wavelength. What happens when a deep water wave starts to feel the bottom? As a deep-water wave reaches shore, at the point where the depth of the water […]
What 3 things affect the speed of sound?
What 3 things affect the speed of sound? Factors Affecting The Speed of Sound The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in […]
What two forces are balanced in any star?
What two forces are balanced in any star? Gravitational forces act to contract the star. Fusion reactions and heat convection act to expand the star. The two forces are balanced and the star remains stable in size and reactions. What does it mean that the energy in the sun is balanced? What does it mean […]
How do we use refraction in everyday life?
How do we use refraction in everyday life? Refraction of light can be seen in many places in our everyday life. It makes objects under a water surface appear closer than they really are. It is what optical lenses are based on, allowing for instruments such as glasses, cameras, binoculars, microscopes, and the human eye. […]

Does cold water help hurricanes?
Does cold water help hurricanes? Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart. Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms. What weakens a hurricane? […]
What is the attraction between particles in a solid?
What is the attraction between particles in a solid? Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. Are solid particles in motion? Particles […]
How many amps are in 220 volts?
What is the most accurate way for calibrating bimetallic thermometers?
What is the most accurate way for calibrating bimetallic thermometers? Bimetallic stemmed thermometers are calibrated using the ice-point method. Calibrate on a regular basis and after using the thermometer with very hot or very cold foods, or after dropping or jarring it. In a clean styrofoam cup, make an ice water slush by filling the […]
