The Oort cloud is the proximate source of observed nearly parabolic, so-called 'new' comets entering the planetary region, and is also the presumed source of the long-period comet flux and the majority of Halley-type comets (HTCs).
The oort cloud is important for understanding the formation of the solar system.
What is oort cloud?It is believed to be an important source of comets that can provide valuable information about the conditions and processes that were present in the early solar system.
Here,
The Oort Cloud is important for understanding the formation of the solar system because it is believed to be a reservoir of icy bodies that formed early in the solar system's history. These icy bodies, which include comets, are thought to have played a key role in the early evolution of the solar system by delivering water and other volatile materials to the inner solar system, including the early Earth.
By studying the composition and properties of comets from the Oort Cloud, scientists can gain insights into the formation and evolution of the solar system and learn more about the conditions that were present in the early solar system.

can you predict a dark room is empty or not with the help of sound? how?
please help me ।
50 points
Answer:
Sound waves can reflect off surfaces. We hear sound reflections as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes.
Soft, rough surfaces are good at absorbing sound. This is why rooms with carpets and curtains do not usually produce lots of echoes.

what supports a white dwarf against the crush of gravity?
Answer: In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.
Explanation:
Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.
What is Degeneracy pressure?Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.
The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

A bullet is fired straight up from a gun with
a muzzle velocity of 166 m/s.
Neglecting air resistance, what will be its
displacement after 8.6 s? The acceleration of
gravity is 9.8 m/s
Answer in units of m.
Explanation:
u=166m/s, v=0(at it's highest point final velocity is zero), a=9.8m/s², t=8.6s
by the formula, S=ut+½at².
S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation
S = 1427.6+362.404
S=1790.004m

What acceleration would you expect a 100 kg individual to experience from a 1000N force?
Answer: 10 m/2^2
F=ma
Explanation:
Force = 1000N
1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)
a = 10 m/s^2

Habiba and selehadin have measured the voltage across a resistor to be 5.26V and the current flowing through in to be 0.41A they work out the resistance .
habiba says the resistance is 12.8 ohms .selehadin disagrees and says that is 13 ohm .
who is correct?.
Considering the definitipn of current, voltage, power, and Ohm's law,
CurrentThe flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.
VoltageThe conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.
Resistance
Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.
This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.
The resistance that is measured in ohms.
Ohm's law
Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.
Mathematically, Watt's law is expressed:
[tex]I=\frac{V}{R}[/tex]
So if you want to find resistance, the expression for its calculation is:
[tex]R=\frac{V}{I}[/tex]
This caseIn this case, you know:
V= 5.26 VI= 0.41 AReplacing:
[tex]R=\frac{5.26 V}{0.41 A}[/tex]
Solving:
R= 12.8 ohms
Habiba is right. The resistance is 12.8 ohms.
