Why gold leaves are used in Electroscope? A gold-leaf type electroscope is a device used to detect the presence of electric charge on a body and its relative amount. They also capture charge leaking through the air that could accumulate on the glass walls, and increase the sensitivity of the instrument. What happened when you […]
What are the 8 elements of art?
What are the 8 elements of art? The eight principles of art are balance, proportion, unity, harmony, variety, emphasis, rhythm, and movement. All of these principles clearly deal with the placement of elements within artwork. What is the element of art line? Line is a mark made using a drawing tool or brush. There are […]
Why is carbon capture expensive?
Why is carbon capture expensive? Direct air capture is “very expensive because the CO2 in the atmosphere is only . 04%,” Herzog tells CNBC, and the technical process of removing carbon dioxide from a gas gets more expensive the lower the concentration of the carbon dioxide gets. Is carbon capture economically viable? But so far, […]

Is beating of drum periodic motion?
Is beating of drum periodic motion? The beating of the drum occurs at defined period. So, it is a periodic motion. Which is periodic wind? Periodic winds blow at regular intervals or in regular cycles. They are winds that result from localised differences in pressure and temperature. For example, land and sea breezes and the […]
What are the main types of star clusters?
What are the main types of star clusters? The three basic types of clusters astronomers have discovered are globular clusters, open clusters, and stellar associations. How do you determine a star cluster? By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime […]
What is the relationship between buoyancy and volume?
What is the relationship between buoyancy and volume? Compressible objects As a floating object rises or falls, the forces external to it change and, as all objects are compressible to some extent or another, so does the object’s volume. Buoyancy depends on volume and so an object’s buoyancy reduces if it is compressed and increases […]
When would you use cumulative frequency?
When would you use cumulative frequency? Cumulative frequency is used to determine the number of observations that lie above (or below) a particular value in a data set. The last value will always be equal to the total for all observations, since all frequencies will already have been added to the previous total. What is […]
