churn out - perform in a mechanical way premier, premiere - perform a work for the first time star - be the star in a performance appear - appear as a character on stage or appear in a play, etc.; "Gielgud appears briefly in this movie"; "She appeared in `Hamlet' on the London ...
4. To engage or schedule: lined up some freelance work for next month; lined up a speaker for graduation.Idioms: all along the line 1. In every place. 2. At every stage or moment. down the line 1. All the way; throughout: Errors are to be found down the line. 2. At a point...
Sound in its simplest form can therefore be described as a pressure wave caused by the vibration of objects. Since sound waves are created due to the vibration of matter, they are classified as mechanical waves and require a medium to propagate, unlike electromagnetic waves (light). ...
How does light interact with matter? How does kinetic energy work? What is the use of lever if its mechanical advantage is (a) more than 1 (b) equal to 1 (c) less than 1? How can you explain work, in regards to electricity? Explain how microscopes can use wave optics to improve ...
What occurs when light passes through matter? How does the expansion of the universe affect light? How does the moon reflect light? How do electromagnetic waves work? How to light up a light bulb without electricity. How does energy travel in a mechanical wave? How does electromagnetic radiatio...
The speed of the wave is often denoted by the Greek letter upsilon, {eq}\upsilon {/eq}. It is the rate at which the wave is able to propagate and spread in a medium and has the units of distance over time or meters per second....
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
Through 2020 and into 2021, we had a glimpse of what a clean transport future might look like. Fewer polluting vehicles on the roads, cleaner air and a healthier natural environment came courtesy of the national lockdowns that accompanied the COVID-19 pandemic. In some cities, nitrogen oxide...
However, a mechanical door called a shutter prevents the imaging light rays from playing on the imaging chip. To take a picture, the shutter is briefly opened and then closed. This act permits the image forming light rays contact the imaging chip. On the surface of the imaging...
Researchers at the University of Vienna collected over 947 hours of giraffe sound recordings, demonstrating the animals would hum in sustained harmony with varying sound wave frequencies. The average frequency of the humming was 92 kHz, which is within the range of human audibility. Humans are able...
