Two common stars are observed by an astronomer. It turns out that the first one is twice as hot as the second. This indicates that the first emits around 16 times as much energy as the second.

<h3>Describe about astronomers?</h3>

The two main categories of astronomers are observational and theoretical. Direct observations of celestial objects are made by observational astronomers, who then evaluate the results. Theoretical astronomers, on the other hand, develop and research models of phenomena that cannot be seen. Because a system of stars or a galaxy has a life cycle that lasts millions to billions of years, astronomers must take photographs of various systems at distinct stages in order to understand how they create, develop, and die. They build models or run simulations using these data to theorize about how various astronomical objects function.

What is the instantaneous speed at 5 seconds? (remember s=d/t)
TEA [102]
5 seconds is a poor time to ask about, because the speed abruptly changes at exactly 5 seconds.

Up until that time, the speed has been 1 m/s. And then, at exactly 5 seconds, it becomes zero.
_________

It's also a poor question because speed is calculated from the distance covered, but the graph shows displacement, not distance. You can't really tell the distance covered from a displacement graph. For example, if an object happens to be moving in a circle around the place where it started, then the total distance covered keeps increasing, but its displacement is constant.

A rocket for use in deep space is to have the capability of boosting a total load (payload plus the rocket frame and engine) of
choli [55]

Answer:

<em>13.54 tons</em>

Explanation:

Let f be the amount of fuel oxidizer needed

v be the speed

The relationship between them is inverse in nature i.e

f ∝ 1/v

f = k/v

If a rocket for use in deep space is to have the capability of boosting a total load (payload plus the rocket frame and engine) of 3.25 metric tons to a speed of 10,000 m/s, then f = 3.25 when v  = 10,000

Substitute and get k

k = fv

k = 3.25 * 10,000

k = 32500

To get the amount of fuel oxidizer required to produce a speed of 2400m/s, we will find f when v = 2400m/s

Recall that f = k/v

f = 32500/2400

f = 13.54 metric tons

<em>Hence the fuel plus oxidizer that will be required is 13.54 tons</em>
