Description : ‘Dead Sea’ is called so because - (1) the water is brackish (2) it does not support any acquatic life (3) it is not favourable for navigation (4) it has no waves
Last Answer : (2) it does not support any acquatic life Explanation: The Dead Sea is a salt lake bordering Jordan to the east and Israel and the West Bank to the west. With 33.7% salinity, it is ... than the ocean. This salinity makes for a harsh environment in which animals cannot flourish, hence its name.
Description : Echo sounding is the technique applied to— (1) measure the depth of the sea (2) measure the amplitude of sound waves (3) record earthquake waves (4) record the density of air in the atmosphere
Last Answer : (1) measure the depth of the sea Explanation: Echo sounding is the technique of using sound pulses to find the depth of water. The interval from the emission of a pulse to reception ... information is then typically used for navigation purposes or in order to obtain depths for charting purposes.
Description : Seismic sea waves which approach the coasts at greater force arc known as – (1) Tides (2) Tsunami (3) Current (4) Cyclone
Last Answer : (2) Tsunami Explanation: A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcanic ... initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves.

Description : Stationary wave is formed by – (1) a transverse wave superposing a longitudinal wave (2) two waves of the same speed superposing (3) two waves of same frequency travelling in the same direction (4) two waves of same frequency travelling in the opposite direction
Last Answer : (4) two waves of same frequency travelling in the opposite direction Explanation: Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in ... and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave.
Description : Two types of waves are formed on a transmission line. What names are given to these waves?
Last Answer : Incident waves from generator to load. Reflected waves from load back to generator.
Description : Standing waves are formed when two sets of waves of equal amplitude and frequency w) are in phase x) are in opposite phase y) move through each other in opposite directions z) are reflected from the same surface
Last Answer : ANSWER: Y -- MOVE THROUGH EACH OTHER IN OPPOSITE DIRECTIONS
