A thin oil slick (no=1.50) floats on water (nw=1.33). When a beam of white light strikes this film at normal incidence from air,
Sedbober [7]

Answer:

The (minimum) thickness of the oil slick is 325 nm.

Explanation:

Let the (minimum) thickness of the oil slick = t_{o}

Therefore:

2t_{o} = (m_{red}+\frac{1}{2})*λ_{red}/n_{o}       (1)

similarly,

2t_{o}=(m_{violet}+\frac{1}{2})*λ_{violet}/n_{o}                                (2)

Thus, equation 1 = equation 2

(m_{red}+\frac{1}{2})*λ_{red} /n_{o} = (m_{violet}+\frac{1}{2})*λ_{violet}/n_{o}

Where:

λ_{red} = 650 nm

λ_{violet} = 390 nm

n_{o} = 1.5

Therefore:

\frac{2m_{violet}+1 }{2n_{red}+1 }=650/390=5/3

This shows that,

m_{violet}=2

m_{red}=1

Thus, using equation 2

t_{o}=\frac{5*390}{2*2*1.5} =325 nm

A particle moves on a line away from its initial position so that after t hours it is s = 6t2 + 2t miles from its initial positi
docker41 [41]
<span>32 mph
   First, let's calculate the location of the particle at t=1, and t=4
 t=1
 s = 6*t^2 + 2*t
 s = 6*1^2 + 2*1
 s = 6 + 2
 s = 8 t = 4
 s = 6*t^2 + 2*t s = 6*4^2 + 2*4
 s = 6*16 + 8
 s = 96 + 8
 s = 104
   So the particle moved from 8 to 104 over the time period of 1 to 4 hours. And the average velocity is simply the distance moved over the time spent. So:
 avg_vel = (104-8)/(4-1) = 96/3 = 32
   And since the units were miles and hours, that means that the average speed of the particle over the interval [1,4] was 32 miles/hour, or 32 mph.</span>

What is the magnitude of the kinetic frictional force
Sophie [7]

Answer:

Magnitude of kinetic force is the product of the normal force and the coefficient of kinetic friction.

Explanation:

The kinetic frictional force is the force which is experienced in the moving surfaces of bodies.The magnitude of the force is affected by the coefficient of kinetic friction between the material of two bodies in contact. Mathematically, it is expressed as;

Fk=μk*η

where;

  • Fk=force of kinetic friction
  • μk=coefficient of kinetic friction
  • η=normal force
