What’s a star? In complete sentences.

1 answer:

5 0

Hello!

A star is a large, spherical burning ball of gas located in outer space. They are made of hot gasses and plasma.

They are born in a nebula which is a large cluster of stardust. Many stars perform nuclear fusion, where hydrogen nuclei combine to create helium. This provides stars energy to burn and prosper for billions of years.

When a star is dying it will begin to lose its power. It will eventually explode in an enormous supernova. This has a chance of creating a black hole. Usually the remnants of the supernova will form another nebula, therefore continuing the cycle of a star.

I hope this helps!

Why can we never prove that a hypothesis is true?

erma4kov [3.2K]

A theorem can be proven (from axioms or prior theorems), using logic.

A hypothesis can be supported by evidence. The more evidence in support of the hypothesis, the more likely the hypothesis is to be correct. However, you’re always at the mercy of contrary evidence appearing in the future, to reduce the likelihood or even invalidate a hypothesis.

A (mathematical) proof suffers no such vulnerability to future evidence, as long as you hold the axioms of the theory to be true, and as long as there was no flaw in the construction of the proof.

A 5,257 kg rocket blasts off to the moon with an acceleration of 76 m/s ^2 what is the net force on the rocket

frutty [35]

Newton's subsequent law expresses that power is corresponding to what exactly is needed for an object of consistent mass to change its speed. This is equivalent to that item's mass increased by its speed increase.

We use Newtons, kilograms, and meters each second squared as our default units, albeit any proper units for mass (grams, ounces, and so forth) or speed (miles each hour out of every second, millimeters per second², and so on) could unquestionably be utilized also - the estimation is the equivalent notwithstanding.

Hence, the appropriate answer will be 399,532.

Net Force = 399532

The light waves have that particular interference from question #1 because they are emitted _____.

Elis [28]

I am attaching the rest of your question so it makes sense,
<span>
Since lasers are made from stacking light waves that add together into a larger wave due to CONSTRUCTIVE INTERFERENCE.
</span>
Then, <span>light waves have that constructive interference (from question #1) because they are emitted IN PHASE with each other.

This means that they arrive at the same point of space with the same characteristics and their effects do not cancel each other, but the opposite, their intensity increases.</span>
