Answer: dry scrubbers are less than 10% efficient at removing particles less than 1μm in size
Explanation:
A dry scrubber or dry scrubber system is one type of scrubber that is used to remove harmful materials from industrial exhaust gases before they are released into the environment. That substance then falls out of the gas stream or is caught in a particle screen.
Answer:
Explanation:
So first, we have to plug in zero and see if we can evaluate this limit simply from that.
When we plug in zero we get: (2e^0-2)/0
e^0 is 1 so we have 2-2/0 or 0/0. So we have an indeterminate form type 0/0.
This means we have to apply L'Hospital's Rule.
As a reminder L'Hospitals Rule is 
Meaning that we take the derivative of the top and bottom function as the approach some value "c". We can do this with a 0/0 indeterminate form.
So:
The derivative of 2e^x - 2 is just 2e^x
and the derivative of x is 1
So we are left with 
Plugging in zero we see this gives us 2 as 2(e^0) = 2(1) = 2.
Hence, = 2
Answer to Question 1:
The behaviour of the students who hastily write what they consider a "C" level essay after being repeatedly told they can't make an "A" or "B" is a consequence of Reinforcement.
The answer, therefore, is D.
Explanation:
Reinforcement in behavioural psychology refers to the process of encouraging or entrenching a belief system or pattern of behaviour. It can also be defined as any stimuli which stimulate a thought pattern and engrains the probability of a specific response to a particular stimulus. Reinforcements are usually more effective when it comes from a person of perceived to be in a position of authority.
The high school students were verbally programmed by the instructor, who has the authority to mark their scripts, into thinking they will never be able to make an "A" or a "B". The result is that the students didn't even try to put in efforts that would have led to an A or a B because even if they did, the instructor has the power to ensure that no one score an "A" or a "B".
The challenge here is not that the students couldn't write "A" grade essays. In their mind, there was no point trying given that the ability lay with the instructor to ensure that what he said will happen. In any case, the instructors intended behavioural response was achieved.
2. The correct answer to the question of Acquisition and Extinction as indicated on the graph is B.
The strength of the response increases then decreases over time.
Acquisition happens when a neutral stimulus turns into a conditioned stimulus.
When a behavior begins to diminish or even disappear completely as a result of the gradual removal of a conditioned response, extinction is said to have occurred.

I believe it is C) 250 million metric tons
although i may be wrong
