Answer: 2.5 m/s
Explanation: The velocity in in uniform circular motion is given by:
v=w^2*r where w is angular frequency
w=2*Pi/T where T is the period
Finally we can calculate v= (2*Pi)^2/T^2*R where R=1 m
The work done against the gravitational force goes into an important form of stored energy that we will explore in this section. ... If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh.
Point C would the greatest
Answer: increases
Explanation:
Because the relationship between hand d is counter
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.
