Answer:

See explanation

Explanation:

Jupiter’s diameter is in fact larger than that of the smallest star, at 140,000 kilometres against 121,000 km for the tiniest star.

However it is mass, not size, that counts. This determines the internal pressure that, if sufficiently high, can overcome the mutual repulsion of hydrogen nuclei and convert these to helium through nuclear fusion. This releases the huge amount of energy that makes stars shine.

If a large cloud of interstellar gas came Jupiter’s way, maybe the planet could gain enough extra mass to start fusion. Fusion would be short lived if it became a brown dwarf, an object midway between star and planet. If it accreted even more mass, just enough to become a true star, it would be a dim red dwarf. Its radiation would barely affect us and it wouldn’t look very different to now. A bigger worry would be Jupiter’s increased mass disrupting the solar system, not to mention the raised temperature of the sun, as a result of it capturing most of the gas cloud.

Exact figures are uncertain, but calculations suggest Jupiter would need to be 80 times as massive as it is to turn into a small red dwarf star. Another possibility, though, is a brown dwarf, which is a kind of half-star. This isn’t massive enough for ordinary hydrogen to fuse into helium as in most stars. Instead it uses the rarer hydrogen isotope deuterium.  It is estimated a brown dwarf needs to be about 13 times the mass of Jupiter.

Answer:

False

Explanation:

Let me put it in numbers. Jupiter has mass of 1.898x10^27Kg, make it 10 times as much and it becomes 1.898x10^28 Kg.

TRAPPIST-1, smallest star ever found has Mass of 1.77x10^29Kg, that is around 93 times larger than the mass of Jupiter.

Clearly 10 times as much is not enough to generate fusion reaction and become a star, in theory Jupiter must be at least 85 times larger than it's current mass to be able to generate fusion reaction and become a star.

So i think we can conclude that if Jupiter were to have 10 times of its own mass, it would not become a star, therefore the given statement is False.

In Figure 21-4 B, does the magnetic field -due to the current carrying wire- curve in a clockwise or counter-clockwise direction
weeeeeb [17]

The magnetic field between the poles of the horseshoe magnet in fig 21.4 B curves in the <u>counter clockwise direction.</u>

The magnetic field lines due to a straight current carrying conductor is given by the right hand thumb rule.  This rule is stated as follows: Imagine holding the current carrying conductor in your right hand with the thumb pointing in the direction of current, then the direction in which your fingers curve around the wire gives the direction of the magnetic field lines. The direction of the magnetic field lines at a point gives the direction of magnetic field at that point.

On applying this rule, it can be seen that the magnetic field  due to the conductor shown in Fig 21.4 B curves in the counter clockwise direction.

makvit [3.9K]

A eclipse starts when one object in space is blocking an observer. Most commonly known as the moon blocking the sun. For us having a visual on eclipses we normally have two eclipses. We have the solar eclipse and the lunar eclipse. These are both very important on the timing and the cycles of the moon. A solar eclipse happens when the moon moves in front of the sun. This will cause a shadow to fall on only a few certain places on earth. Then a lunar eclipse is when the Sun, moon, and earth are perfectly aligned. With the earth being the middle the Sun casts its rays and causes a huge shadow on the moon.

Hope this helped!

How will you show that metals form basic oxides?​
Galina-37 [17]

Answer:

<h2>when metallic oxides react with water they form metallic hydroxides which are basic in nature.to show that these are basic in nature,we should conduct a litmus paper test.in this experiment,we will observe that red litmus turns blue on coming in contact with them. this shows that metallic oxides are basic in nature</h2>

The electrons that produce the picture in a
vredina [299]
Given:
u = 10⁵ m/s, the entrance velocity
v = 2.5 x 10⁶ m/s, the exit velocity
s = 1.6 cm = 0.016 m, distance traveled

Let a = the acceleration.
Then
u² + 2as = v²
(10⁵ m/s)² + 2*(a m/s²)*(0.016 m) = (2.5 x 10⁶ m/s)²
0.032a = 6.25 x 10¹² - 10¹⁰ = 6.24 x 10¹²
a = 1.95 x 10¹⁴ m/s²

Answer: 1.95 x 10¹⁴ m/s²
