What happens to the particles when a liquid boils? Boiling. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles […]
How many seconds does it take to stop a car going 60 mph?
What is relation between distance and displacement?
What is relation between distance and displacement? Distance is a scalar quantity that refers to “how much ground an object has covered” during its motion. Displacement is a vector quantity that refers to “how far out of place an object is”; it is the object’s overall change in position. What is literary displacement? In its […]
What are the 3 zones of a lake?
What are the 3 zones of a lake? Each pond or lake has several different zones that divide the water column from top to bottom and side to side. The zones discussed are the Littoral Zone, Limnetic Zone, Profundal Zone, Euphotic Zone, and Benthic Zone. The Littoral Zone is the shore area of the lake […]
How does a mechanical wave move?
How does a mechanical wave move? A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave. Which wave has […]
What would happen if there was no winter?
What would happen if there was no winter? Originally Answered: What would happen to life on Earth if we did not have seasons? Seasons are caused by the earth’s tilt. Without tilt, there would be no summer season and no winter season. The equator would always be hot and the poles would always be cold. […]
Can AC run DC?
Can AC run DC? You can use AC coils on DC circuits providing you apply enough DC voltage to draw the same amount of current as when operating on AC. Here’s an alternative to rewinding AC coils so that they can operate on DC circuits. It’s a relatively simple procedure requiring some calculations and some […]
Why do some objects float?
Which angular velocity is greater a second hand minute hand and hour hand of a clock?
How do you test if sunglasses are polarized?
How do you test if sunglasses are polarized? Look at a bright, reflective light source (e.g., glass, water, or polished metal) with your shades on. If the light increases in intensity when you tilt your head sideways to around 60 degrees, you’re wearing polarized sunglasses. If there’s no change in quality, they’re just tinted. Where […]
