A thin film of cooking oil ( n = 1.47 ) is spread on a puddle of water ( n = 1.35 ) . What is the minimum thickness D min of the

zlopas [31]

Answer:

The minimum thickness of the oil is 77.55 nm

Explanation:

Given:

Refractive index of oil $n_{o} = 1.47$

Refractive index of water $n_{w} = 1.35$

Wavelength of light $\lambda= 456 \times 10^{-9}$ m

From the equation of thin film interference,

The minimum thickness is given by,

$2n_{o} t = (n+\frac{1}{2}) \lambda$

Where $n = 0,1,2,3.........$ , $t =$ thickness

Here we have to find minimum thickness so we use $n = 0$

$2n_{o} t =( 0+\frac{1}{2} )\lambda$

$t = \frac{\lambda }{4 n_{o} }$

$t = \frac{456 \times 10^{-9} }{4 \times 1.47}$

$t = 77.55 \times 10^{-9}$ m

$t = 77.55$ nm

Therefore, the minimum thickness of the oil is 77.55 nm

1. What net force is required to accelerate a car at a rate of 2 m/s2 if the car has a mass of 3,000 kg?

nataly862011 [7]

Answer:

Net force required to accelerate the car is 6000 N

Explanation:

Force is calculated by the equation, F = Mass × Acceleration

This is based on Newton's Second Law of Motion which states that the force acting on an object is its mass times the acceleration of the object.

Here, mass = 3000 kg and acceleration = 2 m/s²

⇒ Force = Mass × Acceleration

= 3000 × 2 = 6000 N

⇒ F = 6000 N

⇒ M = 3000 kg

⇒ a = 2 m/s²
