The height of the oil column above the water in the vessel is determined as 2 cm.
<h3>
Pressure of the vessel</h3>
The pressure of the vessel due to water, oil and silver poured into the vessel is determined from mercury column.
let level of mercury = 20 cm + 0.5 cm = 20.5 cm
20.5 cmHg = 205 mmHg
1 mmHg = 133.32 Pa
205 mmHg = 27,330.6 Pa
<h3>Height of the liquids in the vessel</h3>
P = ρgh
where;
ρ is the density of water, oil and silver respectively
ρ = 1000 kg/m³ + 881 kg/m³ + 10,800 kg/m³ = 12,681 kg/m³
h = P/(ρg)
h = (27,330.6) / (12,681 x 9.8)
h = 0.22 m
h = 22 cm
<h3>Height of oil column</h3>
Oil is less dense than water and will float on water.
Height of oil column = 22 cm - 20 cm = 2 cm

few plants
Explanation:
Arid and polar regions of the world typically have few plant species. The plant species in such environment are called xerophytes. They are plants that can live in an area with little to no precipitation.
- Arid regions of the world are about the most driest in the world with very high diurnal temperature range.
- Polar regions are frigid and cold all year round.
- Both arid and polar regions have little to no precipitation all year round.
- They have poor soils to support plant growth.
- This is why they both have few plants.

1.) Law of Induction.
2.) Increase Winding Count
Answer:
1.8nA
Explanation:
I = dq/dt
I = 9.0 × 10 ^-12 / 0.5 × 10^-3
I = 1.8 × 10× 10^-8
