Answer:
Reflection
Explanation:
<em>The particles in the atmosphere only reflect the color blue and and all others are absorbed. Only the reflected colors can be seen from our eyes not the absorbed ones</em>
Both the experimental group and the control group are exposed to the same type of treatment.
I think the answer could be that it could result in resonance.
There is not much to go from in this question. Specify whether the are on the same wave length or on separate.
If the 2 waves are on the same wave length and going towards each other with the same amplitude, that would result in them colliding and forming a larger amplitude, or something called constructive interference.
I hope this helps you!
The least value varies depends on ammeter range. In the given question, ammeter range is not mentioned. So, the least value of an ammeter is 0.1 or 0.5 (depends on ammeter range).
<u>Explanation:</u>
The least value of an ammeter is the measure of the smallest number which can be observed in ammeter. So the least value will be varying depending upon its range. If we consider the range of ammeter is 30 A and the scale readings are 10 numbers, then the least value will be 30/10 = 3 A per scale.
So the least value is determined as 
So among the given options 0.1 is most suitable for an ammeter with range of 3 A with 30 divisions.
