Answer:
The magnitude of electric field is 
in downward.
Explanation:
Given that,
Force 
Charge q= -2.00 μC
We know that,
Charge is negative, then the electric field in the opposite direction of the exerted force.
We need to calculate the magnitude of electric field
Using formula of electric force
Negative sign shows the opposite direction of electric force.
Hence, The magnitude of electric field is in downward.
Answer:
The reason that it takes longer to get the water to boiling temperature than it is to cool it down again is because heating in the most simple sense is inefficient and will cause a lot if energy lost while cooling is to be turn's into quite a efficient process.

Answer:
The movement of polar bears help figure out the impact of global warming in the arctic. Since polar bears travel over the frozen ocean they are able to determine the rate it melts as the bears retreat inland. The worse global warming become the quicker it becomes hotter in the arctic which is bad by the way.
