This is somewhat far-fetched, and it's a real stretch.  But if you have to pick one of the choices, then <em>choice-B</em> is the one you have to pick.

How is Saturn like a miniature model of the solar system ?  

Let us count some of the ways:

-- The Sun, a big gas ball, is the central body of the solar system.  The planet Saturn, a big gas ball, is the central body of the Saturn system.

-- Many tiny bodies, which we call planets and comets, are in orbit around the Sun.  Many tiny bodies, which we call Saturn's moons, are in orbit around Saturn.

-- A particularly dense band of particularly tiny bodies are in orbit around the Sun.  We call them asteroids.  A particularly dense band of particularly tiny bodies are in orbit around Saturn.  We call them Saturn's rings.

-- The Sun has way more mass than all the tiny bodies in orbit around it.  Saturn has way more mass than all the tiny bodies in orbit around it.

How is Saturn NOT like a miniature model of the solar system ?

Let us count some of the ways:

-- The Sun is composed mainly of Hydrogen, with quite bit of Helium mixed in.  Saturn has a lot of Hydrogen and Helium on the inside, but also a lot of ammonia ice, methane ice, and water ice in its outer layers.  The Sun has none of those.

-- The temperature and pressure in the core of the sun are so great that nuclear fusion ignited there about 4.6 billion years ago, and the Sun became a star.  The outer parts of the Sun are much cooler ... only about 9,900 degrees.   Saturn is not a star.  There's no nuclear fusion anywhere in it, and its average temperature inside and out is about 290 degrees BELOW zero.

-- The Sun's average density is about 26% of the average density of Earth.  Saturn's average density is about half of that.  In fact, if you could find a big enough pool full of water, the Sun would sink in it, but Saturn would float in it.

I would say B because the rest of them are false.

Because Saturn is made of gas

Saturn is smaller than Jupiter

And it takes 29 years for Saturn to orbit the sun

Hope This Helps!     Have A Nice Day!!

Light bulb is connected to a 110-V source. What is the resistance of this bulb if it is a 100-W bulb
masya89 [10]

Answer:

<h2>121ohms</h2>

Explanation:

Formula used for calculating power P = current * voltage

P = IV

From ohms law, V = IR where R is the resistance. Substituting V = IR into the formula for calculating power, we will have;

P = IV

P =(V/R)V

P = V²/R

Given parameters

Power rating of the bulb P = 100 Watts

Source voltage V = 110V

Required

Resistance of the bulb R

Substituting the given parameters into the formula for calculating power to get Resistance R;

P = V²/R

100 = 110²/R

R = 110²/100

R = 110 * 110/100

R = 12100/100

R = 121 ohms

<em>Hence, the resistance of this bulb is 121 ohms</em>

Studentka2010 [4]

Answer:

58.44 C

Explanation:

Electric field is found by

E=\frac {\sigma}{\epsilon_o}=\frac {Q}{A\epsilon_o}

Therefore, the charge is

Q=EA\epsilon_o&#10;

Q= 4.00 ✕ 10^{6} N/C*1.65 *10^{6} m^{2}*8.854*10^{-12}= 58.4364 C&#10;

Therefore, required charge is 58.44 C
