Answer:
True
Explanation:
The wind will exert a force on a body no matter the size of the object
The force on an object due to wind is given by

The unit is Newton
Where,
= Density of air
A = Surface area of object
v = Velocity of air
Hence, it is true that the force of the wind over an area increases as the square of the wind velocity.
Answer:
ehh help me solve this my question
Explanation:
I dont know it and btw I am 14
Answer:
For the control experiment:
of aqueous solution of erioglaucine has absorbance of 
From Lambert-Beer's law we know:

Here; e is the molar absorptivity coefficient of erioglaucine
l = length of cuvette in which the solution is taken = 
A sorbance by the erioglaucine = total absorbance - absorbance by distilled 
So; by putting the values in the above equation; we get:

So; 
The molar absorptivity coefficient of erioglaucine is 
The absorbance of erioglaucine in distilled water (contaminated with metal ions) is: 
The absorbance of distilled water is 
So; absorbance of erioglaucine itself is : 
Again using Lambert Beer law; we get:


c = 0.198/5.65 M = 0.035 M
The concentration of the erioglaucine is 
Explanation:
Answer:
Yes they are found in same period
