A solar sail allows a spacecraft to use radiation pressure for propulsion, similar to the way wind propels a sailboat. The sails
Neporo4naja [7]

Answer:

  F = 2 I A / c

Explanation:

The radiation pressure on a reflective surface is

        P = 2 S / c

Where S is the Poynting Vector and c the speed of light

Furthermore pressure is defined as the ratio of force to area

        P = F / A

Let's replace

        F / A = 2 S / c

        F = 2 S A / c

The poynting vector is the power per unit area that is equal to the intensity

      S = I

       F = 2 I A / c

Is boiling a pot of water an example of Thermodynamics?
garri49 [273]

Answer: I think I have the answer to your problem!!

A pot of boiling water is a nice everyday example to explain internal energy, heat, and work. However, it's not a good choice for applying the first law of thermodynamics, because the boiling pot isn't a closed system.

An incident light ray hits a plane surface at 20 degrees (hint: remember where the angle is measured from). What is the angle be
Juli2301 [7.4K]

Answer:

40^{\circ}

Explanation:

The incident angle is 20^{\circ} so the reflected ray will also be 20^{\circ}.

The normal divides the angle between the incident and reflected ray. So, the angle between them would be

\text{Incident angle}+\text{Reflected angle}=20+20=40^{\circ}

So, the angle between the incident and reflected rays is 40^{\circ}.
