The peak intensity of radiation from Star Beta is 350 nm. In what spectral band is this? UV, radio waves, visible light, or infared radiation

[ad_1]

Answer:

UV (Ultraviolet Waves)

Explanation:

As we know that wavelength range of visible light is given as 450 nm to 750 nm.

so here as we move towards higher wavelength range then the energy of electromagnetic waves will decrease as we know it is given as

E = frac{hc}{lambda}

now on increasing wavelength we will shifted to infrared waves while on decreasing the wavelength energy of electromagnetic waves will increase and this will shift towards ultraviolet waves

Since the given wavelength is less than the wavelength of visible light so here it is Ultraviolet Waves

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

A sun-sized star will spend most of its lifetime as a:

[ad_1]

First, let’s talk about temperature. As I mentioned above, the color of a star comes from its surface temperature. A star that emits mostly red light will have a surface temperature of about 3,500 Kelvin. Just for comparison, the Sun’s surface temperature is about 6,000 Kelvin and emits yellow/white light.

Red Dwarf Stars

The first kind of red stars are red dwarfs. These are actually the most common stars in the Universe. The smallest red dwarf stars can be 7.5% the mass of our Sun, and be as large as about half the mass of the Sun. Even a star with this little mass has enough temperature and pressure at its core to carry out nuclear fusion. This is where atoms of hydrogen are fused into atoms of helium; this process releases lots and lots of heat.

Red dwarfs generate much less energy than a larger star like our Sun. In fact, a red dwarf emits 1/10,000th the energy. Even the largest red dwarf only has about 10% of the Sun’s luminosity. Red dwarfs use their hydrogen fuel slowly and so they last a very long time. It’s believed that a red dwarf star could survive for 10 trillion years.

Red Giant Stars

Stars like our Sun spend most of their lives as main sequence stars with a surface temperature that’s much hotter than a red star. But at the end of their lives, when they have used up all their hydrogen fuel, these medium-sized stars will puff out much bigger than their original size – these are red giants. When our Sun becomes a red giant, it will expand out to encompass the orbit of the Earth. After a few hundred million years, it will puff its outer layers and become a white dwarf star.

They start out as regular stars, but they grow to such an enormous size that their heat is spread out across a much larger surface area. This is why they appear very bright, but still have a red color.

Red Supergiant

The biggest stars in the Universe are the red supergiants. They’re not the most massive; Betelgeuse, for example, only has about 20 times the mass of the Sun. But the largest red supergiants can expand out to be more than 1500 times the size of the Sun. Imagine a star that engulfed the orbit of Saturn! Just like the red giants, red supergiants occur when a star has used up the hydrogen fuel in its core, and then expand out during their helium-burning phase. Red supergiants will have the mass to continue fusing elements in their cores, all the way up to iron.

Stars probably only exist as red supergiants for a few hundred thousand years; a million at most. At the end of this period, the star will have used up all the fuel it can in its core; most will detonate as Type II supernovae.

We have written many articles about stars here on Universe Today. Here’s an article about a planet surviving when its star became a red giant, and here’s a deathwatch on a red giant star.

Use two isosceles triangle below to make a star

[ad_1]

The triangle ABC is similar to triangle LMP. The order here is very important. The letters correspond to one another
A corresponds to L (first letters of each sequence) 
B corresponds to M (second letters of each sequence)
C corresponds to P (third letters of each sequence)

In a similar fashion, the segments also correspond to one another. 
AB corresponds to LM (first two letters of each sequence)
AC corresponds to LP (first and last letters of each sequence)
BC corresponds to MP (last two letters of each sequence)

————————————

AB corresponds to LM. AB is 4 units long. LM is 2 units long. So AB is twice as long as LM. This ratio (of 2:1) will be applied to every paired corresponding value.

Also, the right angle is at angle M for triangle LMP. The right angle will be at angle B for triangle ABC (since B corresponds to M). The answer will have an x coordinate of 7. So the answer is either choice B or choice C.

If we move 4 units down from point B, we land on (7,-10). That isn’t listed as an answer choice. Let’s try moving 4 units up from point B. We land on (7,-2). This is an answer choice

So the final answer is choice C) (7,-2)

Answer:

Option D is correct answer.

Step-by-step explanation:

Independent events are those in which the occurrence of one event does not affect the occurrence of the second.

A – observing the numeric outcomes of rolling the same number cube twice consecutively. This is independent event.

B – observing the numeric outcomes of rolling two number cubes at the same time. This is independent event. As two number cubes are not dependent on each other.

C – observing the numeric outcomes of rolling three or more number cubes at the same time. This is independent event.

D – observing the numeric outcomes of rolling a number cube once, then rolling it again, ignoring the outcome if it matches the first. This is a dependent event as a single cube is rolled again and the outcomes are dependent.

Answer: The speed of the river current = 3mph

Step-by-step explanation:

Let x be the speed of the river current.  

Given: The speed of Tinh in still water = 6 mph

Let d be the distance from dock to park.

Now, speed in upstream = 6-x

Time taken in upstream = 2 hours

Distance covered upstream =d=speed*time=2(6-x)….(1)

Speed in downstream = 6+x

Time taken in downstream = 40 minutes ==frac{40}{60}hour= 2/3 hour

Distance covered downstream =d=speed*time=frac{2}{3}(6+x)…..(1)

From (1) and (2), we have

2(6-x)=frac{2}{3}(6+x)\Rightarrow (6-x)=frac{1}{3}(6+x)\Rightarrow 3(6-x)=6+x\Rightarrow 18-3x=6+x\Rightarrow x+3x=18-6\Rightarrow 4x=12\Rightarrow x=3

Hence, The speed of the river current = 3mph

Which of the following can be determined by studying the spectrum of a star? the chemicals in the atmosphere of the star the motion of the star the temperature of the atmosphere of the star all of the above

[ad_1]

Answer:

The medium determines the speed of the wave, the wavelength and frequency.

Explanation:For different media the speed of the wave will variate, because each media have different properties. The following equation makes a relation between the speed of the wave, the wavelength and the frequency:

v = lambda.nu (1)

Where v is the speed of the wave, lambda is the wavelength and nu is the frequency

Equation 1 shows that the speed of the wave is directly proportional to the product of the wavelength and the frequency. If the speed is lower the wavelength will decrease but the frequency increase, as is shown in equation 2:

lambda = frac{v}{nu}   (2)

Equation 1 can be rewritten for the case of the frequency:

nu = frac{v}{lambda}     (3)

So, according with equation 3, if the speed is higher the frequency will increase but the wavelength will decrease (inversely proportional).

March 4, 1933, was perhaps the Great Depression’s darkest hour. The stock market had plunged 85% from its high in 1929, and nearly one-fourth of the workforce was unemployed. In the cities, jobless men were lining up for soup and bread. In rural areas, farmers whose land was being foreclosed were talking openly of revolution. The crowd that gathered in front of the Capitol that day to watch Franklin D. Roosevelt’s Inauguration had all but given up on America. They were, a reporter observed, “as silent as a group of mourners around a grave.”
Roosevelt’s Inaugural Address was a pitch-perfect combination of optimism (“The only thing we have to fear is fear itself”), consolation (the nation’s problems “concern, thank God, only material things”) and resolve (“This nation asks for action, and action now”). The speech won rave reviews. Even the rock-ribbed Republican Chicago Tribune lauded its “dominant note of courageous confidence.” F.D.R. had buoyed the spirits of the American people — and nearly 500,000 of them wrote to him at the White House in the following week to tell him so.
Hours after the Inauguration, Roosevelt made history in a more behind-the-scenes way. He gathered his Cabinet in his White House office and had Justice Benjamin Cardozo swear them in as a group, the first time that had ever been done. F.D.R. joked that he was doing it so they could “receive an extra day’s pay,” but the real reason was that he wanted his team to get to work immediately.
And that team came through brilliantly. In the next 100 days — O.K., 105, but who’s counting? — his Administration shepherded 15 major bills through Congress. It was the most intense period of lawmaking ever undertaken by Congress — a “presidential barrage of ideas and programs,” historian Arthur Schlesinger Jr. observed, “unlike anything known to American history.”
