Answer: Mutton
Explanation:
Mutton refers to the flesh of the mature ram or ewe at least one year old.
Answer:
Real and inverted
Explanation:
Magnification of a lens is defined as the ratio of the height of the image to the height of the object.
Where
h' is the height of image
h is the height of the object
It is also defined as the ratio of image distance to the object distance.
Here, m = -0.6
Negative sign shows the image is inverted. So, the formed image will be real and inverted.
Sound intensity is inversely proportional to the square of the distance between the source and the receiver.
That is
I = k/r^2
where
k = constant
r = radius
When r=1, the intensity is I₁ = k/1 = k
When r=3, the intensity I₂ = k/3² = k/9
Therefore
I₂ = I₁ /9
In decibels,
I = 10 log₁₀(I/I₀)
where I₀ = reference intensity
When r=1,
10 log₁₀ (I₁/I₀) = 270
When r =3,
10 log₁₀ (I₂/I₀) = 10 log₁₀ [(I₂/I₁)*(I₁/I₀)]
= 10 log₁₀ [(1/9)*(I₁/I₀)]
= 10 log₁₀(1/9) + 270
= 260.5
Answer: 260.5 dB (nearest tenth)
