acceleration= change in velocity/ time taken
initial velocity=(36×1000m)/3600
= 10m/s
final velocity= (54×1000m)/3600
=15m/s
change in velocity= final - initial
=15 - 10
=5m/s
time taken = 5s
acceleration=15/5
=3metre per second square

Answer:
Pollution
Climate change
Explanation:
The destruction of the coral reef can be attributed to pollution and climate change.
The pollution of the atmosphere by greenhouse gases such as carbon dioxide causes the average temperature of the planet to increase, a phenomenon that is referred to as <u>global warming</u>. Global warming also causes an increase in the temperature of sea waters which can lead to the death of microscopic algae, causing coral bleaching.
An increase in the concentration of carbon dioxide in the atmosphere also causes <u>ocean acidification</u> which, in turn, reduces the availability of materials required to form the calcium carbonate of the coral reef. In extreme cases, acidification of the ocean can cause the dissolution of the coral skeletons.
