Answer:
The difference in the decibel corresponses to a constant difference in the loudness perceived.
The refore the sound intensity from the orchestra is like 100 times that of the violin.
Explanation:
40 dB is 20 dB more power than 20 dB is. 20 dB more means 100 times as much.
Higher resolution cannot be achieved with a light microscope because wavelength of light is larger that wavelength of electrons.
<h3>What is light microscope?</h3>
Light microscope is defined as the type of microscope that makes use of visible light to magnify objects into images that can be observed.
The wavelength of light is larger than that of the electrons, therefore, higher resolution cannot be achieved with a light microscope.

Complete Question
The complete question is shown on the first uploaded image
Answer:
the value of 
Explanation:
From the question we are told that
The equation is (x + y = 40)
The first value of x is 
The second equation is (0.75x + 1.5y = 40)
So substituting 
=>
Now substituting y and into second equation
=> 
So
Answer: d₂ = 170 mGya
Explanation:
the relationship between absonbed 'd' and exposure 'E' is given as;
D(Gv) = F . x (AS/xB)
F is a conversion coefficient depending on medium
so we can simply write
d₁/d₂ = x₁/x₂
Given that;
our x₁ = 60 mAs, x₂ = 120 mAs, d₁ = 85 mGya, d₂ = ?
from the given formula,
d₂ = (x₂d₁ / x₁)
now we substitute
d₂ = (120 × 85) / 60
d₂ = 170 mGya
∴ if 120 mAa is used, the new exposure will be 170 mGya
