In an experiment to estimate the diameter of an oil molecule,an oil drop of diameter 0.05cm spreads over a circular patch whose diameter is 20cm.
¡)determine the volume of the oil drop.
v = π(20/2)^2 * 0.05 = 5π cm^3
To determine the volume of the oil drop, we can use the formula for the volume of a sphere:
Volume = (4/3) * π * (radius)^3
Since we are given the diameter of the oil drop (0.05 cm), we need to first find the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 0.05 cm / 2 = 0.025 cm
Now we can calculate the volume using the formula:
Volume = (4/3) * π * (0.025 cm)^3
Calculating this using the value of π as 3.14, we get:
Volume = (4/3) * 3.14 * (0.025 cm)^3
= (4/3) * 3.14 * (0.025 cm) * (0.025 cm) * (0.025 cm)
= 0.0000654 cm^3
Therefore, the volume of the oil drop is approximately 0.0000654 cm^3.
To determine the volume of the oil drop, we can use the formula for the volume of a sphere. The formula for the volume of a sphere is V = (4/3) * π * r^3, where V is the volume and r is the radius.
In this case, we are given the diameter of the oil drop, which is 0.05cm. The radius of the oil drop can be calculated by dividing the diameter by 2. So, the radius (r) is equal to 0.05cm/2 = 0.025cm.
Now we can substitute the radius into the volume formula:
V = (4/3) * π * (0.025cm)^3
To get the volume of the oil drop, simply calculate this expression.
