A piece of glass has a thin film of gasoline floating on it. A beam of light is shining perpendicular on the film. If the wavele

Usimov [2.4K]

Answer:

200 nm

Explanation:

Refractive index of gasoline = 1.4

Wavelength = 560 nm

t = Thickness of film

m = Order = 1

Wavelength is given by

$\lambda=\dfrac{560}{1.4}=400\ nm$

We have the relation

$2t=m\lambda\\\Rightarrow t=\dfrac{m\lambda}{2}\\\Rightarrow t=\dfrac{1\times 400}{2}\\\Rightarrow t=200\ nm$

The thickness of the film is 200 nm

What is the average power developed by a motor as it lifts a 400.-kilogram mass at constant speed through a vertical distance of

Tomtit [17]

Answer:

The average power developed by a motor is 4905 Watts.

Explanation:

The average power is given by:

$P = \frac{W}{t}$

Where:

W: is the work

t: is the time = 8.0 s

First, let's find the work:

$W = F*d$

Where:

F: is the force

d: is the displacement = 10.0 m

The force is in the vertical motion, and since the movement of the mass is at constant speed the force is:

$F = mg = 400 kg*9.81 m/s^{2} = 3924 N$

Hence, the average power is:

$P = \frac{F*d}{t} = \frac{3924 N*10.0 m}{8.0 s} = 4905 J/s = 4905 W$

Therefore, the average power developed by a motor is 4905 Watts.

I hope it helps you!
