QveST [7]

Answer:

8.67×10⁻⁶ N/m²

Explanation:

p = Momentum of a photon

E = Energy of a photon

c = Speed of light

I = Intensity of light

Force = dp/dt

p=\frac{E}{c}

\\\Rightarrow F=\frac{\frac{dE}{dt}}{c}

As given in question

F=2\frac{\frac{dE}{dt}}{c}

Now F/A = Pressure

P=\frac{2I}{c}\\\Rightarrow P=\frac{2\times 1300}{3\times 10^{8}}\\\Rightarrow P=8.67\times 10^{-6}\ N/m^2

∴ Magnitude of the pressure on the sail is 8.67×10⁻⁶ N/m²

andriy [413]

the distance between Jupiter and the Sun is 7800 Million kilometers.  Option A is correct.

<h3>What is the Astronomical unit?</h3>

It is a unit of measurement of length for very large distances such as the distance between the sun and a planet. It is denoted as AU.

An astronomical unit is a distance between the earth and the sun.

1 AU = 150 million kilometers.

So, the distance between Jupiter and the Sun is Million km,

Distance =  5.2 x 150 Million kilometers

Distance = 7800 million kilometers

Therefore, the distance between Jupiter and the Sun is 7800 Million kilometers.
