Answer:

Thousands of meteorites, which are fragments of asteroids that fall to Earth, have been recovered. These primitive objects provide the best ages for the time of formation of the Solar System. There are more than 70 meteorites, of different types, whose ages have been measured using radiometric dating techniques.

Meteorites that fall to Earth represent some of the original, diverse materials that formed planets billions of years ago. By studying meteorites we can learn about early conditions and processes in the solar system's history.

Umm.. maybe my answer is not what you needed

I'm sorry ❤️

Answer:

Scientists think that meteorites can get chemicals such as isopropyl cyanide from a space cloud. So, it’s possible that a meteor that had acquired isopropyl cyanide struck Earth and brought life to the planet.

In the night sky, stars often look like a multitude of bright lights barely distinguishable from one another. But the fact is th

Mrac [35]

Answer:

The correct answer is -

differences: color, brightness, temperature, size, and mass

similarities: They are balls of gas, mostly hydrogen and helium

Explanation:

Stars look mostly the same from anywhere or any place and tough to differentiate or distinguish one from another. Star can be different on the various ground even they look similar from far away.

Stars can be of various colors from red to blue and brightness can be different as well, color depends on temperature, and brightness depends on the size of the star.

Stars are grouped by the size that ranges from dwarf to supergiant. The temperature of the stars also varies which affects the color and brightness as well.

Stars are the big balls of gases composed of mainly helium and hydrogen all are always under a nuclear reaction.

The count in a bacteria culture was 100 after 20 minutes and 2000 after 40 minutes. Assuming the count grows exponentially, What

Afina-wow [57]

Answer:

Explanation:

Let X be the number of bacteria at time t, and Xo be the initial number of bacteria

Bacteria grows exponentially, the exponential growth model is thus:

X = Xo $e^{kt}$

[e is the exponential sign]

k is the growth constant = growth rate

At t = 20 minutes, X = 100

At t = 40 minutes, X = 2000

Substituting that into the formula

(i) ... 100 = Xo $e^{k20}$

(ii) ... 2000 = Xo $e^{k40}$

Divide (ii) by (i)

$\frac{2000}{100} = \frac{Xoe^{40k} } {Xoe^{20k}}$

20 = $e^{40k-20k} = e^{20k}$

[Xo cancels Xo. Division of values raised to a power is done by subtracting their powers]

Take the natural log of both sides

㏑20 = 20k

[taking the ㏑ cancels the exponential]

k = $\frac{ln20}{20}$

We can now substitute k to solve one of the equations

substituting k in (ii): 2000 = Xo $e\frac{ln 20}{20}.^{40}$

2000 = Xo $e^{0.15*40}$

2000 = Xo $e^{6}$

Making Xo the subject of the formula

Xo = $\frac{2000}{e^{6} }$

Xo is approximately 5 cells.

THE DOUBLING TIME

The doubling time is the time it takes for the population to double, so 5 cells become 10 cells

Since Xo = 5

Given that X = Xo $e^{kt}$

When X=10,

10 = 5 $e^{0.15t}$

solving for t:

$e^{0.15t} = \frac{10}{5}$

Take ln of both sides

0.15t = ln 2

t = $\frac{ln2}{0.15}$

t =4.62 minutes

POPULATION AFTER 65 MINUTES

X = 5 $e^{0.15*65}$

X = 85770

WHEN WILL THE POPULATION REACH 12000

12000 = 5 $e^{0.15t}$

$e^{0.15t}$ =240

take ln of both sides

0.15t = ln 2400

t = 51.89 minutes (approximately 52 minutes)

Explain how scientists got the space station up in space. What problem did they

natta225 [31]

Answer:

scientists got the space station up in space in to small pieces.

Explanation:

The main problem which was faced by the scientist was that there was no powerful rocket which has the ability to lift the whole space station due to its more weight and carry it to the space against the powerful force of gravity. So for solving this problem, space station is taken into pieces into the space and then these pieces should be join to build the space station.
