Asteroids, often known as minor planets, are stony, airless leftovers of our solar system's early development about 4.6 billion years ago.
The majority of this ancient space junk may be found in the main asteroid belt, orbiting the Sun between Mars and Jupiter. Asteroids range in size from Vesta, the largest at 329 miles (530 kilometers) in diameter, to asteroids as small as 33 feet (10 meters). The cumulative mass of all asteroids is less than that of the Earth's Moon.

If you were to build a pipe organ with open-tube pipes spanning the range from 25 hz to 19 khz. The speed of sound in air is 343 m/s
Building a pipe organ with open-tube pipes spanning the range from 25 hz to 19 khz will require the length of the shortest pipe to be 0.018m
What is Length?This is defined as the measurement or extent of a substance from end to end. The formula is shown below:
L = v/f where v is speed , f is frequency
f1 = 25hz , f2 = 19khz
The length for both sides is seen below:
l1 = 343/25 = 13.72m
l2 = 343/19000 = 0.018m.

If c is a positive real number and ak=klnc, for what values of c, if any, does the infinite series ∑k=1[infinity]ak converge?
There is no value of c such that the infinite series converges.
How to analyze the converge of an infinite series
Convergence is a characteristic of infinite series, in which a sum tends to be a given number when n tends to +∞.
In this question we must prove for which values of c the infinite series may converge.
There are different criteria to prove whether a given series converges or not, one of the most used criteria is the ratio criterion, which states that:
[tex]r = \frac{a_{k+1}}{a_{k}}[/tex], where the series converges if and only if r > 1. (1)
If we know that [tex]a_{k} = k\cdot \ln c[/tex], then the rational formula is:
[tex]r = \frac{(k+1)\cdot \ln c}{k\cdot \ln c}[/tex]
[tex]r = 1 + \frac{1}{k}[/tex]
We notice that resulting expression does not depend on c and is greater than 1. Therefore, there is no value of c such that the infinite series converges. [tex]\blacksquare[/tex]
RemarkIf [tex]c[/tex] is a positive real number and [tex]a_{k} = k\cdot \ln c[/tex], for what values of [tex]c[/tex], if any, does the infinite series [tex]\sum_{k=1}^{\infty} a_{k}[/tex] converge?

There is no values of c, for the infinite series ∑k=1[infinity]ak to be converge when c is a positive real number.
What do you mean by infinite series?The infinite series is the sum of addition of a sequence in which the number of terms present are infinite.
[tex]a_1+a_2+a_3....+a_n[/tex]
Here, ([tex]a_n[/tex]) is the nth term of the sequence. For infinite series, the ratio criterion can be given as,
[tex]r=\dfrac{a_{k+1}}{a_k}[/tex]
If c is a positive real number and
[tex]a_k=k\ln c[/tex]
Put the value in above shown ratio,
[tex]r=\dfrac{(k+1)\ln c}{k\ln c}\\r=\dfrac{k\ln c}{k\ln c}+\dfrac{\ln c}{k\ln c}\\r=1+\dfrac{1}{k}[/tex]
With the value of r, we can say whether the series is converge or not. This value of r does not depends on c.

What happens when light waves strike a mirror? question 5 options: most of the light waves are refracted. most of the light waves are absorbed. most of the light waves are scattered. most of the light waves are reflected.
Answer: "Most of the light waves are reflected", might be the correct answer.
Explanation: it might be the correct answer because the light waves spread out from the source in all directions, and upon striking a mirror, are reflected at an angle determined by the angle at which the light arrives. The reflection process inverts each wave back-to-front, which is why a reverse image is observed.
Answer:
most light waves are reflected
explanation:
when light hits a mirror it bounces back at the same angle it hit this is called reflection refraction on the other hand Refraction is the bending of light

What are the seasonal changes in the weasel in florida and the weasel in wyoming
Answer:
The differences between the Florida's weasel and in Wyoming's is that I can see that in Wyoming it has a lot of snow so Wyoming's weasel fur is more thicker than Florida's weasel.
Explanation:
Overmore, in Florida's weasel the weasel's fur is much more less then Wyoming's weasel's fur. Subsequently, their fur color is very different. In Wyoming's weasel fur, it's white fur help them blend in the snow. In Florida's weasel fur, it's brown and help blend in the grass(soil).
Weasels are small animals with long tail. Their diet will change in each seasons and will causes consecutive changes in body weight also.
What is seasonal change?The changes occurs in a living body or in a material with respect to different seasons is called seasonal changes.Weasels have coats that change from light brown to white in the winter. They are also known as ermines or short-tailed weasels.
In both the spring and the fall, the hue of their bodies changes, starting at their belly and moving outward. Long-tailed weasels and other species may also turn at least partially white.
The hue shift is caused by daylight duration rather than temperature. Weasels may therefore appear dazzling white in the winter against a brown environment before snow begins to fall. This makes them easy prey for larger predators like foxes, martens, and badgers during milder winters.
These little creatures eat a lot. Winter weasels forage often and consume roughly 40% of their body weight each day. Winter weasels have coats that change from light brown to white in the winter.
These pests, which can weigh as little as two ounces, are vicious and may attack prey that is larger than themselves. Weasels have excellent senses and are highly nimble. Because of this, they are difficult to catch and remove, both for humans and for predators.
Weasels are a sign of a healthy population of rodents or other prey on a property in the winter. The pests frequently reserve a portion of their meals for later.

An empty coal car of a train of mass 8000 kg is moving at 12 m/s along rails. 24000 kg of coal is dumped into the car from a motionless bin. What is the speed of the coal car afterward?
Answer:
3 m/s
Explanation:
Initial = Final
Mass * Velocity = Mass *Velocity
8000kg * 12m/s = (8000kg+ 24000kg) * (Final Velocity)
(96000 kgm/s) / (32000kg) = (Final Velocity)
Final Velocity = 3 m/s
The speed of the coal car afterward is 3 m/s if an empty coal car of a train of mass 8000 kg is moving at 12 m/s along rails. 24000 kg of coal is dumped into the car from a motionless bin.
What is the law of conservation of momentum?The momentum of the body before the contact is always equal to the momentum of the body after the collision, according to the law of conservation of momentum.
According to the law of conservation of momentum;
Momentum before collision =Momentum after collision
We have:
Mass of the empty coal car of train M(e) = 8000 kg
Speed V(e) = 12 m/s
Mass of the coal M(c) = 24000 kg
Let's suppose the speed of the coal car afterward V(c)
M(e) ×V(e) = (M(c)+M(e))× V(c)
8000×12 = (24000+8000)×V(c)
V(c) = 3 m/s
Thus, the speed of the coal car afterward is 3 m/s if an empty coal car of a train of mass 8000 kg is moving at 12 m/s along rails. 24000 kg of coal is dumped into the car from a motionless bin.

A solid weighs weighs 20g in air,a8.2g in a liquid and 18g in water. Calculate
i. Relative density of the body
ii. Relative density of the liquid
iii. Density of the liquid
Answer:
Weight of the body in air = 20gf ( Wa)
Weight of the body in water = 18gf ( Ws)
Weight of the body in liquid =18.2gf ( Wl)
Now,
The loss of weight in the water = 20 - 18 or, 2 gf
So the relative density of the body is = Wa / ( wa - ws )
= 20 / 2
= 10
2) The weight loss in liquid = 20 - 18.2 or, 1.8 gf
So the relative density of the liquid is =( Wa - Wl ) / ( Wa - Ws )
= 1.8 / 2
= 0.9
