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.

How much time does it take light from a flash camera to reach a subject 6.0 meters across a room in scientific notation?
wariber [46]

The time it takes light from a flash camera to reach a subject 6.0 meters across a room in scientific notation is 2.0 *10^-8 s.

<u>Explanation:</u>

<u>Given</u>

t=?

d=6m

v=3*10^8 m/s

we  have,  v=d/t

here t=d/v

t=6m/3*10^8 m/s

v=2*10^-8 m/s

The time it takes light from a flash camera to reach a subject 6.0 meters across a room in scientific notation is 2.0 *10^-8 s.

Rufina [12.5K]
A) Expanding. We know this because it has a similar effect with sound. When a car goes by the pitch gets deeper and deeper. It's because you're receiving less waves. Same thing for light but instead of a pitch it's light, and the farther spread the waves - the redder, the closer and more contracted - the bluer

A rifle is aimed horizontally at a target 50.0 m away. The bullet hits the target 2.90 cm below the aim point. . . Whats the bul
Marina CMI [18]
The problem ask to calculate the bullet's flight time and the bullet's speed as it left the barrel. So base on the problem, the answer would be that the flight time is 0.076 seconds and the speed of the bullet is 657.9 m/s. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications.
