To tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.50•10^6 N, one at an angle 19.0° west of north, a

irina1246 [14]

Answer:

Work done by a tug boat, W = 1.735 x 10⁸ J

Explanation:

Given,

The of each tugboat, F = 1.5 x 10⁶ N

The angle of each tugboat forms with the resultant force, θ = 19°

The displacement of the supertanker, s = 710 m

The individual tugboat will be responsible for the displacement, d = 710/2

= 355 m

The displacement component in each tugboat direction = 355 · sin θ meter

Therefore, the work done by each tugboat is

W = F x S joules

Substituting the values in the above equation

W = 1.5 x 10⁶ x 355 · sin θ

= 1.735 x 10⁸ J

Hence, the work done by each tugboat is, W = 1.735 x 10⁸ J

A film of oil that has an index of refraction of 1.45 rests on an optically flat piece of glass of index of refraction n = 1.60.

blagie [28]

Answer:

442.75862 nm

Explanation:

m = Order

n = Refractive index

$\lambda$ = Wavelength

We have the relation of thickness and wavelength given by

$2nt=m\lambda$

The consecutive spectral line is given by

$2nt=(m+1)\lambda$

So,

$\lambda=\dfrac{2nt}{m}\\\Rightarrow 642=\dfrac{2nt}{m}$

and

$428=\dfrac{2nt}{m+1}$

Dividing the wavelengths we get

$\dfrac{642}{428}=\dfrac{m+1}{m}\\\Rightarrow 1.5 m=m+1\\\Rightarrow m=\frac{1}{0.5}\\\Rightarrow m=2$

$t=\dfrac{m\lambda}{2n}\\\Rightarrow t=\dfrac{2\lambda}{2n}\\\Rightarrow t=\dfrac{642}{1.45}\\\Rightarrow t=442.75862\ nm$

The film thickness of oil is 442.75862 nm
