Based on the trend produced by the dose - response graph, it would be best to evacuate the residents in other to prevent the increasing percentage of deaths due to the rising level of pollutant A.
- The curve shows that the pollutant level in mg/kg of pollutant A is still increasing, hence, groundwater monitoring alone won't be the best decision to make.
- Since the pollutant level is still increasing, then the spill level still need effective monitoring.
- Evacuation of residents seems to be the best decision that should be taken based on the information interpreted on the graph.
Therefore, Evacuating residents to prevent rising death percentage is required as the pollutant level is yet to subside.

On July 19th, 1985 Christa McAuliffe was selected as the first teacher to go to space by NASA. Her dream was to be the first teacher to go to space with all her lessons. Her daughter keeps her dream alive today by setting up 40 schools called the McAuliffe Centre.
Force = mass * acceleration
mass = Force/acceleration
= 36/2
mass = 18 kg
Answer:
The magnitude of the electric field in the second case will be 
of the electric field in the first case
Explanation:
The electric field at a distance 
< R from the center of the sphere is given by
the formula 
= 
where R is the radius of the sphere, and, Q is the charge uniformly distributed on the sphere.
It is given that the same charge Q is distributed uniformly throughout a sphere of radius 2R and we have to find the electric field at same distance from the center.
In the second case the electric field will be given by
= 
Therefore the magnitude of the electric field in the second case will be of the electric field in the first case.
Answer:
It is easier to stop the bicycle moving at a lower velocity because it will require a <em>smaller force</em> to stop it when compared to a bicycle with a higher velocity that needs a<em> bigger force.</em>
Explanation:
The question above is related to "Newton's Law of Motion." According to the <em>Third Law of Motion</em>, whenever an object exerts a force on another object <em>(action force)</em>, an equal force is exerted against it. This force is of the same magnitude but opposite direction.
When it comes to moving bicycles, the force that stops their movement is called "friction." Applying the law of motion, the higher the speed, the higher the force<em> </em>that is needed to stop it while the lower the speed, the lower the force<em> </em>that is needed to stop it.
