A stone is dropped is dropped from the top of a tower 500 m high into a pond of water at the base of the tower . when is the Splash heard at the top ? Given,g= 10 m s‐² and speed of sound = 340 m s‐²...?????! |
|
Answer» Height of the tower, s = 500 m VELOCITY of SOUND, v = 340 m sˆ’1 Acceleration due to gravity, G = 10 m sˆ’2 Initial velocity of the stone, u = 0 (since the stone is initially at rest) Time taken by the stone to fall to the base of the tower, t1 According to the second equation of motion: S = ut1 + 1/2gt12 500 = 0 x t1 + 1/2 x 10 x t12 t12 = 100 t1 = 10s Now, time taken by the sound to reach the top from the base of the tower, t2= 500/340 = 1.47 s Therefore, the splash is heard at the top after time, t Where, t= t1 + t2 = 10 + 1.47 = 11.47 s. |

WHAT IS A COMET?EXPLAIN?HOW THEY ARE FORMED? |
|
Answer» Answer: A comet is a ball of mostly ICE that moves around in outer space. Comets are often described as "dirty snowballs".The orbital inclinations of comets are usually high and not near the ecliptic where most solar system objects are found. Most of them are long-period comets and come from the Kuiper belt. Explanation: Comets are basically dusty snowballs which orbit the Sun. They are made of ices, such as water, carbon dioxide, ammonia and methane, mixed with dust. These materials came from the time when the Solar System was formed. Comets have an icy center (nucleus) surrounded by a large cloud of gas and dust (called the coma). The coma is created as the ice in the nucleus is warmed by the Sun and vaporizes. Comets can develop TWO tails as they travel closer to the Sun: a straight gas tail and a CURVED dust tail. The gas tail is created by the solar wind, pushing gas away from the comet's coma and pointing straight back from the Sun. The dust in the coma is not affected by magnetic fields but is vaporized by the Sun's heat, and forms a curved tail which follows the comet's orbit. How are Comets formed? Comets are made up of dust, ice, carbon-dioxide, ammonia, methane etc. The building block of comet is dust PARTICLES coated with water ice and other molecules. These dust particles combine to form icy rocks that join TOGETHER under the force of gravity. |
