Answer:
dₒ/dᵢ = 0.32
Explanation:
From the question given above, the following data were obtained:
Object height (Hₒ) = 4 mm
Image height (Hᵢ) = 1.25 cm
Ratio of object distance (dₒ) to image distance (dᵢ) [dₒ/dᵢ] =?
Next, we shall convert 4 mm to cm. This can be obtained as follow:
10 mm = 1 cm
Therefore,
4 mm = 4 mm × 1 cm / 10 mm
4 mm = 0.4 cm
Next, we shall determine the magnification of the lens. This can be obtained as follow:
Object height (Hₒ) = 4 mm
Image height (Hᵢ) = 1.25 cm
Magnification (M ) =?
M = Hᵢ/Hₒ
M = 1.25 / 0.4
M = 3.125
Finally, we shall determine the ratio of object distance (dₒ) to image distance (dᵢ). This can be obtained as follow:
Magnification (M) = 3.125
Ratio of object distance (dₒ) to image distance (dᵢ) [dₒ/dᵢ] =?
Magnification (M) = image distance (dᵢ) / object distance (dₒ)
M = dᵢ/dₒ
Invert
1/M = dₒ/dᵢ
1/3.125 = dₒ/dᵢ
dₒ/dᵢ = 0.32
Therefore, the ratio of object distance (dₒ) to image distance (dᵢ) [dₒ/dᵢ] is 0.32
Answer:when whatever ur using is changing like when u add two things together then mix it up and it changes into something new
the color can change, the way it’s formed can change the gas the smell and the temperature can change
Explanation:
both cpts are minus. look the way they are pointing.
xcpt less neg than y cpt.
last choice.
Out of the given salts, decreases in solubility as the temperature increases.
Answer: Option B
<u>Explanation:</u>
Here we are talking about Cerium (III) Sulphate which is an inorganic compound, commonly known as Cerous Sulphate. Its chemical formula is . This salt has a monoclinic crystal structure and appears off-white in colour.
It’s solubility in water is 9.25 g/100ml at the temperature of 20, that decreases with the increase in temperature and that’s why it’s counted amongst those few salts that has less solubility when increase temperature.
