Answer:
probably liquid cause it can be contained easily
Time = (distance covered) / (speed)
Time = (2,000 m) / (330 m/s)
<em>Time = 6.06 seconds</em>
Answer:
Explanation:
heat lost by block of copper
= mass x specific heat x fall in temperature
= .04 x 385 x ( 95 - 24 )
= 1093.4 J
Heat gained by water
= .105 x 4200 x ( 24 - T ) ; Here T is initial temperature of water .
= 441 ( 24 - T )
heat lost = heat gained
1093.4 = 441 ( 24 - T )
24 - T = 2.48
T = 21.52 ℃
Karst topography is created by the chemical weathering process of CARBONATION. Carbonation affects limestone and other carbonate rocks. The action of carbonation creates a distinctive landscape of little surface drainage, sink holes, caves and cockpits.
Rain water mixes with carbon dioxide in the atmosphere to form a weak carbonic acid. The carbonic acid then reacts with the calcium carbonate in the rocks to form a soluble calcium bicarbonate that is easily washed away by water.
