Answer:
D. All of the above
Explanation:
Global warming may cause all of the given choices.
Global warming is the rise in surface temperature. This is due to the trapping of heat within the earth surface.
It is as a result of huge amount of greenhouse gases within our atmosphere. They typically permit short wave radiations to escape and they do not allow short wave radiation to pass through. This in turn produces heat.
- The heat can melt polar ices and glaciers.
- This in turn will cause sea levels to rise.
- Also, the ocean temperature will generally increase due to this.

Answer:
0.81 m/s^2
Explanation:
A child rides a bicycle from rest
The child reaches a velocity of 3.8m/s
The time is 4.7 secs
Therefore the acceleration can be calculated as follows
v= u + at
3.8= 0 + a(4.7)
3.8= 0 + 4.7a
3.8-0= 4.7a
3.8= 4.7a
a= 3.8/4.7
= 0.81 m/s^2
Hence the acceleration is 0.81 m/s^2
