Answer:
A differentiated body is a body that has been heated to the point where it is are further from the sun larger have no solid surface and have many more moons Smaller chunks of material vaporize completely as they pass through its atmosphere
Explanation:
Hope it helps..A body is said to be differentiated when it has been heated to the extent where it is bigger, farther from the sun, has no hard surface, and has a lot more moons. Smaller pieces of the materials entirely evaporate as they pass through their environment.
What is Planet?An enormous, spherical celestial object known as a planet is neither a star nor a remain. The nebular theory, which states that an interstellar cloud collapses out of a nebula to form a young protostar that orbits the sun by a protoplanetary disk, is now the best argument for planet formation. By slowly accumulating material under the influence of gravity, or accretion, planets form in this disk.
The terrestrial planets Mercury, Venus, Earth, and Mars, as well as the planetary nebulae Jupiter, Saturn, Uranus, and Neptune, total at least eight planets in the Solar System. These planets all rotate around axes that seem to be inclined relative to their corresponding polar axes.

How is blue colour made?
Answer:
In terms of the light spectrum, blue is a primary color, which means that it is one of the base colors that exist in the universe and it cannot be created by combining different colors together. The primary pigment colors are cyan, magenta, and yellow. Cyan absorbs red, yellow absorbs blue, and magenta absorbs green.

En un recipiente con mercurio (13.6 gr/cm3) se sumerge completamente un cuerpo de 900 gramos de masa. AL medir su peso aparente este marca 2.94 newton en el dinamómetro. Cual es la densidad del cuerpo (kg/m3)
Answer:
ρ = 20.4 kg / m³
Explanation:
For this exercise we use Archimedes' principle, the thrust on a submerged body is equal to the weight of the released liquid
B = ρ g V_liquid (1)
let's write the equilibrium equation
F -W + B = 0
B = W -F
let's calculate
B = 0.900 9.8 - 2.94
B = 5.88 N
From equation 1
V_{liquid} = [tex]\frac{B}{\rho_{Hg} g}[/tex]
V_{liquid} = [tex]\frac{5.88}{13.6 \ 10^3 \ 9.8}[/tex]
V_{liquid} = 4.41176 10⁻⁵ m³
in this case it is indicated that the body is completely submerged
V_body = V_liquid = V
the definition of density is
ρ = m / V
ρ = [tex]\frac{0.900 \ 10^{-3}}{ 4.41176 \ 10^{-5} }[/tex]
ρ = 2.04 10¹ kg / m³
ρ = 20.4 kg / m³

How much thermal energy is absorbed when 145 g of water at 23ºC is heated until it boils and turns into vapour?
Answer:
the thermal energy absorbed is 46,893 J
Explanation:
Given;
mass of the water, m = 145 g = 0.145 kg
initial temperature of the water, t₁ = 23 ⁰C
final temperature of the water, t₂ = 100 ⁰C
specific heat capacity of water, c = 4,200 J/kg.⁰C
The thermal energy absorbed is calculated as;
H = mcΔt
H = 0.145 x 4,200 x (100 - 23)
H = 46,893J
Therefore, the thermal energy absorbed is 46,893J

An object is placed on a surface. A student tries to apply various combinations of forces on the object. Which pair of forces will not move the object?
Answer:
See Explanation
Explanation:
The question is incomplete, as there are no diagrams or options to provide more information to the question.
The general explanation is as follows:
For the object not to move
(1): The forces acting on the object must opposite each other. i.e. if force A acts at the right (or positive direction), force B will act at the left (or negative direction).
(2) The two forces must be equal.
So, for instance:
If the pair of forces are 5N and 5N in opposite directions, the object wil not move.
However, if one of the forces is greater, the object will move towards the direction of the greater force.

Answer: The items listed in the attached file is correctly matched below.
Explanation:
51.) Temperature --> ( Kelvin). This is the correct option as the standard international unit of temperature is measured in Kelvin.
52.) Needle --> ( wedge). An example of a wedge is a needle as they are simple machine designed to make work easier.
53.) Wood --> ( non - magnetic material). This is the correct option as wood can not be attracted by a magnet.
54.) Door knob--> (wheel and axle). The door knob is a type of wheel and axle as it has a wheel portion which is the knob and an axle which is the rod in the door that turns the same axis.
55.) Ramp --> (inclined plane). A ramp is an inclined plane which has a sloping surface.
56.) Like forces --> (repels each other). In an electrostatic field, two charged objects repels each other if they have like forces.
57.) Mass --> ( kilogram). This is the correct option as the standard international unit of mass is measured in kilogram.
58.) Friction --> ( oppose motion). This is correct as friction is the force that poses resistance to a moving object.
59.) Cobalt coin -->( magnetic material). This is the correct option as cobalt coin can be attracted by a magnet.
60.) Lemon crusher --> ( Class 2 lever). This is correct as the lemon (load) is at the middle of the fulcrum ( squeezer) and the effort (hand)
61.) Sew saw -->( Class 1 lever). This is correct as in first class lever type of machine, the fulcrum is in-between the load and the effort.
62.) Wheel and axle --> ( Grooved wheel with rope around)
63.) Unlike forces --> ( attracts each other). In an electrostatic field, two charged objects attracts each other if they have unlike forces ( that is, one is positive and the other is negative).
64.) Earth pulls everything towards --> (Gravitational force). This is correct as stated by Newton's law of universal gravitation. This law states that every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
65.) Wedge --> (Device to split object apart). This is correct as wedge is a type of simple machine which is used to split objects apart.
Answer:
The items with their corresponding match is presented as follows;
51. Temperature ↔ Kelvin
52. Needle ↔ Wedge
53. Wood ↔ Non-magnetic material

Harish runs on a straight path with the velocity of 16 m/s . How long distance will he cover in 2 minutes ?
Answer:
Harish went 1.92 Km in 2 minutes.
Explanation:
Harish is running at 16 m/s (Meters per second) and we need to find how far he goes in 2 minutes.
We can use this formula to calulate the distance:
m/s x time
We know that Harish is going 16m/s so let's plug that in:
16 (m/s) x time
We also should know that 2 minutes is 120 seconds - Let's plug that in too:
16 (m/s) x 120 (Seconds)
Now we calculate:
16 x 120 = 1920
Harish went 1,920 meters in 2 minutes.
Even though we have a correct answer, we can still make it easier to read by converting meters into kilometers.
1 Kilometer (Km) is equal to 1,000 meters.
All we need to do now is divide 1,920 by 1,000 and that will gove us our simplified answer of:
1.92 Km
Answer:
1.92 km
Explanation:
I will explain you:
2×60=120
we have to take 16×120=1920km bro

A boom is to be dropped from moving helicopter on the ground. Explain how can it hut the target ?
Answer:
A bomb that is dropped from a moving helicopter doesn't fall directly downward rather it follows the parabolic path as it were thrown horizontally from a height with certain initial velocity.

d. changing refractive index of gases in the atmosphere
Explanation:
light from a star passes through the atmosphere to reach our eyes. however, the layers of gases in the atmosphere are in constant motion, so the light gets bent and appears to be flickering.

Write a scientific explanation about weather or not a single cell constitutes a system. (CER)
Answer:
Weather such as raining has water molecules/droplets thats been evaporated from the ocean and other areas that's wet, the water will connect and soon the mass of the water will become heavy causing rainfall. Snow in another case has been caused to freeze from low climates creating a snow flake to fall from the sky. Hail is another case however the water that becomes ice is far more larger.
The variety of activities that take place daily in our atmosphere makes up for the weather.
What is the weather like?The weather varies across the globe and changes over a few minutes, hours, days, and weeks. The troposphere, the region of Earth's atmosphere closest to the surface, is where most weather occurs.
Changes in air pressure determine the weather that occurs in a given place. The weight of the enormous quantities of air molecules that make up the atmosphere is what causes air pressure.
Usually, clear, blue skies are seen when air pressure is high. The high pressure prevents clouds from developing by causing air to flow down and fan out as it gets close to the ground.
Low air pressure causes air to move together before converging upward, where it rises, cools, and forms clouds.
