The wall is now more positively charged than the balloon. […]

What are advantages of using microwaves? Advantages of Microwaves Supports larger bandwidth and hence more information is transmitted. More antenna gain is possible. Higher data rates are transmitted as the bandwidth is more. Antenna size gets reduced, as the frequencies are higher. Low power consumption as the signals are of higher frequencies. What are the […]

What are some examples of salinity? Primary salinity occurs naturally in soils and waters. Examples of naturally occurring saline areas include salt lakes, salt pans, salt marshes and salt flats. Secondary salinity is salting that results from human activities, usually land development and agriculture. What is the meaning of salinity? Salinity (/səˈlɪnɪti/) is the saltiness […]
